  • (2021-08-20) Wojciech Górski: Doesn't work properly unfortunately
  • (2021-08-18) Smayan Sahu: for those who are having problems with it not working ------> https://github.com/upman/gchat-themes/tree/2 <--- the fixes are on github
  • (2021-08-18) Bryan Saunders: Used to use this all the time, but it has been broken since June '21 with no sign of any updates. Had to un-install.
  • (2021-08-17) Domenico Cotugno: It's unfortunate, but this extension no longer works. For those looking for an alternative, the NightEye extension (https://chrome.google.com/webstore/detail/night-eye-dark-mode-on-an/alncdjedloppbablonallfbkeiknmkdi?hl=en) works well to keep my Google Chat in Dark Mode, both in the Web App version as well as on chat.google.com.
  • (2021-08-12) Erik Neff: I'd give this extension a 4 or 5 star rating if it was updated, but as it stands now, it's unusable due to the room names being illegible until you click them, and the body of conversations not being dark. I'm sure it's because Google made a bunch of changes to the Chat UI a few months ago and the developer hasn't updated it since. Hopefully he or she comes back and makes the requisite changes or finds someone else who can...
  • (2021-08-12) Schrena: Dark Mode is incomplete. It still leaves a large chuck of the page with a bright white background. It's tedious, nearing impossible, to set your own dark mode because the sections aren't clearly labeled. So you can't tell which section on the page belong to which label within the extension.
  • (2021-08-12) Shawn Hayes: Doesn't work, and appears to have been abandoned by the developer. The dark mode it applies for chat is horribly broken, and the main chat field is still bright white
  • (2021-08-11) Mario Flores: Dark theme mode doesn't work in chat panel, background still white. Theme colors should be customizables
  • (2021-08-11) loucrem: cant change background for chat like it shows
  • (2021-08-05) Tony Zielinski: Used to work, as many have pointed out, but doesn't anymore. If/when they update this extension to fix it, I would give it 5 stars.
  • (2021-07-29) Adam Mortimer: Did not update the correct fields. As this is, it does not work.
  • (2021-07-22) David Valencia: Doesn't even work half the time
  • (2021-07-20) kwiyuus: It was only dark on the side and the color was too dark that I wasn't able to see what the names of the chats were.
  • (2021-07-16) Tilde: It doesn't work correctly anymore. Many colors don't properly update - namely, the background of the chat itself. Hopefully it'll get fixed, because as far as I've found it's the only one.
  • (2021-07-15) Kupok Natsu: Two weeks is adequate time to respond to an issue and implement a fix. Update, Release source, or remove.
  • (2021-07-13) James Nickerson: Close! I'm glad this extension exists, and I look forward to using it once it's been updated to work with the current version.
  • (2021-07-06) Gaven Finch: It used be be okay, but recently it's not working at all.
  • (2021-07-05) Joey Anderson: Doesn't work anymore. When/if it does work again there needs to be more presets. Takes at least 30 mins to get a cohesive theme going manually. Dark mode was nice though. Not sure why google doesn't have built in theme options but since they don't I hope this extension gets working again. Much respect to the devs here for making the extension in the first place but I can't leave a good review right now.
  • (2021-07-04) Erik Neff: Piling on with the others - I like the idea for the plugin, and it was great until Google Chat made some updates a month ago or so, and now all the styling looks quite bad. Hopefully the developer will see this and make the requisite updates, and I'll revise my review.
  • (2021-06-29) Brian Kraus: Need to pop in another low review, not because this is an inherently bad extension, but because it looks like Google changed things and the extension hasn't updated to account for them. Confirming that as of 29 Jun 2021, it looks like the underlying CSS has changed again, and the extension is horribly broken. Agree w/ others that Dark Mode doesn't work. But if you go in and custom change the colors on the elements, you'll really see the problem. Effectively, you change "chat area background color", but what really changes is "sidebar area"; that isn't 100% correct, but that is the overall issue. So I suspect Google changed its classes and ID's in the background and the extension just needs to get updated. A real bummer, because everything was working just fine up to about 1-2 weeks ago, at least for me.
  • (2021-06-29) Roy Bowling: Come on. This has got to be the simplest thing in the world. "Dark Mode", means dark fonts and backgrounds EVERYWHERE. When I have a conversation or a room open and the background is blazingly white, that is the exact opposite dark mode. Either fix this or do us all a favor and remove yourself from the web store. Nobody needs this frustration right now.
  • (2021-06-28) Kelli S: Downloaded this last week and it worked like a charm. However, today my Google Chat is back to white background. I removed the addon then downloaded it again. Turned it to default, then back to Dark mode, still nothing. Help! My eyes!!
  • (2021-06-25) Taariq Firfirey: nearly there, the setup of custom themes is to complex for the lay person, its difficult to figure out what all the different items means without trial and error. so simplify the options and have what you currently have as advanced setup. also room and room names text in the list of rooms are same colour as background. think a recent update in chats broke the setup
  • (2021-06-23) Eric Condrey: The extension automatically goes to dark mode which is nice because then I don't have to use the web broswer extension I use and don't necessarily want on all sites all the time JUST to have it dark on my chats. It unfortunately does not provide other chat themes at the moment though, hoping that gets fixed. It also hides the text when you go to settings within the chat (I have to to do a CTRL+A situation over the entire page to get the text to show up). Will bump up rating when more themes become available again.
  • (2021-06-14) Clayton Burnett: rooms text doesnt show up with dark theme enabled. will bump right back up once fixed.
  • (2021-06-14) Bruno Tuescher: Hello there, it is a cool addon :-) But it would be great to have the following improvements implemented: - Dark mode for chatrooms makes the chatroom name unreadable (black font and black background) - Name is not readable if you select a face 2 face chat
  • (2021-06-13) Justin Tew: Adds a dark theme like it says but font colors are unreadable
  • (2021-06-09) Elizabeth Rud: No longer working. No slack mode and all modes are broke.
  • (2021-06-07) Xander Komarov: 1. Dark theme is applied by default, no theme selection and no custom theme settings (they're just gone from menu). 2. In Dark theme there is room names and some other text fields that have same color as the background, so meaned texts are not readable anymore. To conclude, the extension is completely broken, don't use it until fix will come.
  • (2021-06-04) Cristian Olmedo: Funciona a medias, los themes que se puede customizar funcionan mal y trae solo un theme dark muy malo
  • (2021-06-04) Maxim Stoylov: After the Chat update, ROOMS names are not visible as the text appears to be Black.
  • (2021-06-02) Quinn Lincoln: It was working great until today when I can't see the names of the groups at all.
  • (2021-06-01) DANIEL AUGUSTO VAZQUEZ NIEVES: Funciona bien siempre y cuando no cambies el tamaño de la ventana, al maximizar google chat se hace un desastre con los colores y hay que reiniciarlo para que vuelva a cargar el esquema de colores correcto.
  • (2021-06-01) Melle Koning: For some reason the settings are not available anymore, that is, the google chat theme icon for the extension is not visible anymore and the dark theme colours are hiding texts, so there is no way to change the theme settings anymore?
  • (2021-06-01) Olivier Durand: Where is the Slack theme ?
  • (2021-05-31) Chris Kienstra: The theme was updated today. :-) Perfect for my tired eyes.
  • (2021-05-31) Lohith S: Can we get an Out Of the Box Material Theme like MS Code ? Setting the custom theme rgba somehow doesn't work with Chat, Rooms. The Names of the Rooms are in Black, so when you set a dark theme, there is nothing to set the color of the names and almost all the Pop Ups are washed out in white.
  • (2021-05-31) Anderson Nascimento: after last update it stopped working
  • (2021-05-31) Igor Valente: Hi there, Liking this extension very much. Just have a problem when it's in Dark Mode. I can't read the names of the rooms as the letters are dark as well. Could you please check that? Thanks in advance
  • (2021-05-30) Brady McEwen: Doesn't do anything, no drop down, yes I watched the video.
  • (2021-05-27) Gian Oliveira: after last update it stopped working
  • (2021-05-27) Jordan - Agência Slim: It seems not being regularly updated anymore, it doesnt apply dark theme at all.
  • (2021-05-26) Maurits Bruinsma: Nice theme, but not working anymore as of recent update of google chats
  • (2021-05-25) Tom DOUX: Does not work with the new update of google chat. Any update scheduled ?
  • (2021-05-20) Eric Rosenquist: Worked well until Google updated Chat to use different URLs. Don't bother installing it unless you see that there's been an update after May 2021.
  • (2021-05-09) Jack Shannon: This worked well on one account but not well on the other. The problem is with the list of sites that the extension can read and change the data on. On the working account, the URL is "chat.google.com" while on the other, as soon as I enter the URL, it changes to "mail.google.com/chat" If you could change the list of sites that the extension needs access to to include the second variation on the URL, I would change my rating to 5 stars, as well as have a more thorough enjoyment of the extension. *EDIT: There is a new Google Chat update that has a hover color over your active chat. If you could add a setting to change the color of that, as well as issue mentioned originally, I would be very pleased with this extension. *EDIT: Extension no longer works, as Google has fully transitioned to the new "mail.google.com/chat" URL. Until this is fixed, the extension will not function and my rating will remain at one star.
  • (2021-05-08) Freak3672: Stopped working after recent domain update. I've started using DARK READER, it is also working same. If anyone wants to use you can install the extension from the link below. https://chrome.google.com/webstore/detail/dark-reader/eimadpbcbfnmbkopoojfekhnkhdbieeh?hl=es
  • (2021-05-05) Antonio Gimenez: Desde la reciente actualización en "google chat" ninguna extensión para esta plataforma funciona (incluyendo esta). Hasta la semana pasada, funcionaba perfecto para mis pretensiones.
  • (2021-05-04) Jalen Tang: IT'S EPIC I LOVE THE BACKGROUD
  • (2021-05-03) Eddie Hendez: I CANT SEE MY TEXT WHEN IM TYPING UGH

  • (2021-08-25, v:0.0.2) Richa Jain: How do I change the color of the Room Name?
    In Dark Mode the default color of all Room Names is black because of which it is unreadable unless selected.
  • (2021-08-23, v:0.0.2) Sophie E.: Fix it! We need you
    Hi! White Google Chat is sooo boring, we need you!
  • (2021-08-22, v:0.0.2) Ron Zoscak: There seems to be a newer version at https://github.com/upman/gchat-copy/releases/tag/0.0.11
    There seems to be a newer version at https://github.com/upman/gchat-copy/releases/tag/0.0.11 Has anyone tried it? It requires you to use developer mode and to install from a downloaded file, which I don't feel comfortable doing.
  • (2021-08-11, v:0.0.2) loucrem: please fix google chat themes

  • (2021-08-02, v:0.0.2) Gray Taylor: dark mode not working
    please read thru the comments to find out how long it has been broken. please fix the dark mode on this extension.
  • (2021-07-08, v:0.0.2) Nick Claywell: Chat background coloring is broken
    As others have reported, the actual background of the chat portion of the window is stuck at white and cannot be changed to any other color. This started recently - probably after a recent Chrome update?
  • (2021-07-08, v:0.0.2) Pulkit Vashistha: Can't change chat background color
    The chat background color remains blazingly white and there is no option to customize it. Am I doing something wrong or is this a prob for all?
  • (2021-07-06, v:0.0.2) Alex Temus: partially fundtional dark mode
    The dark mode is only working on a few banners on google chats when I updated to the newest version of chats. Please address
  • (2021-07-06, v:0.0.2) Elizabeth Rud: gchat theme status
    Will you be fixing GChat Themes? Please let me know. I will hang in there if you are working on it, otherwise I would rather know if it's never getting fixed.
  • (2021-07-02, v:0.0.2) Kevin Krantz: Dark Mode Broke
    All was well until earlier this week, when the color stopped working in background of an actual chat. Additionally, when in dark mode, I can't read the names of rooms in dark mode -- the text blends with the background color.
  • (2021-06-30, v:0.0.2) Gray Taylor: dark mode broken?
    only the left side takes on a darker color - the default dark mode theme is not working at all. help!
  • (2021-06-30, v:0.0.2) Sunny Leo: Dark mode is not working anymore....maybe google changed the code?
    Something is not right ... I believe it started a day or two ago... Dark mode was working completely fine until recently and now, it only applies to a portion of the UI. Sad. Now, my eyes started hurting. Kindly look into this issue at your earliest. Thank you.
  • (2021-06-29, v:0.0.2) Roy Bowling: Dark Mode background not applying to background of individual conversations
    As the title says. Dark Mode (or any other custom background color) somehow only applies to the background of the app. Anytime I open a direct message or a room the background of the thread is blazingly white. Come on. Why even publish this extension if it doesn't work?
  • (2021-06-22, v:0.0.2) Charles Painter: Chat Convo Customization
    Couple of suggestions. Swap my messages to they're on the right, similar to the way Google Messages in Android is, also, add ability to change the message background color so it's different from the people we're chatting with. If these are already possible in the web browser extension, please let me know how to change them.
  • (2021-06-03, v:0.0.2) John Cassella: Color stuff is still really broken
    Firstly I want to second/third/etc. the vote to hopefully fix the font color for the room list in dark mode its completely useless and annoying. Also if possible add a setting to change the highlight color of the background when you have selected a room or user.. the bright grey doesn't work in dark mode very well either.. There are a lot of color settings that don't seem to do anything or are mis-labeled at this point please maybe try looking into which ones still work or do anything at all vs the ones which seem to be non-functional. Third I noticed this morning that after setting dark mode / custom settings , if you resize the width of the app window the background color settings for the whole UI except the conversation thread section go back to white background and they can never be changed back without re-launching the app.. This extension is LIFE to so many people please please please fix it up to make it as awesome as it can be thank you!
  • (2021-06-01, v:0.0.2) Yee Ling Yap: FONT COLOR
    The theme is great but could you please fix the small bug on the font color of the chat room names? Please change it to white color so that the names are readable. Thanks.
  • (2021-05-31, v:0.0.2) Samo2165: Chatroom font colors on google chat app
    The extensions works great with the google chat app now, but the fonts for the chat room names are black so it makes it impossible to read the names of the rooms. Please change the font color to white.
  • (2021-05-31, v:0.0.2) Pascale Oberacker: Small problem
    Hi there, thanks a lot for the update, but there seems to be still one small issue. In the regular browser version of Google Chat, everything works perfectly now, but the App version seems to be using a different name for the chatroom font colors, so those always stay black, which makes them pretty much unreadable in dark mode. Could you have a look at that, please? Thank you!

    Google has added a highlight 'bubble' on the selected chat in the left list which doesn't seem to be affected by any of the theme overrides in this plugin. Making it difficult to see the item when using a dark theme (light text on light background).
  • (2021-04-06, v:0.0.1) nicoful: No longer works
    Hi. Your extension no longer work :( Reason: Google changed the URL from "chat.google.com" to "mail.google.com/chat/". Could you update your extension? Thank you very much!
  • (2021-03-03, v:0.0.1) Brian Tomazic: Added mail.google.com domain
    This extension only works against the chat.google.com domain, but for me the chat.google.com domain forwards to mail.google.com.
  • (2021-03-01, v:0.0.1) Matt Blackledge: No Longer working
    As the title says - the extension worked perfectly until just a few days ago when it suddenly stopped working. In the drop-down menu it says "Can't read or change site's data", and the text is grayed out. As is "Options" just underneath. I think this might be an issue with Google recently changing the URL from chat.google.com/* to mail.google.com/*/#chat, which causes the extension to not trigger.

    I think this is where I changed the color settings and such when I clicked on the Google Chat extensions icon. When I do that now, the Google Chat Themes is greyed out and I can't seem to go to where I could customize the theme.
