  • (2021-12-15) Michael Bolanos: Awesome addin!!!
  • (2021-06-05) Antony Booth: A great extension. Enabling Javascript and having a built in jquery library, makes tweaking sites easy. I use it to add classes to elements, remove panels from pages, resize sections like a canvas with css, debounce searches on inputs, add my own buttons to pages for ease of use and scrape data by querying the dom and use the mutationobserver to watch for changes and act on them. This extension is like a macro tool that allows me to customize some sites I use to enter or retrieve information from more efficiently, while cleaning up junk like splash notices, subscription blockers, cookie notices, notification requests etc and use the page real estate for the content I care about, like a full size map instead of one surrounded by adverts, banners, menus or buttons I never use.
  • (2020-07-28) Rafael Mizar Zita: I was looking to inject custom css and js in certain pages to battle against the new distractions (games tab, marketplace) that facebook (and other sites) comes up with. I was looking at Greasemonkey and found it too complicated for my needs. This one really fit the bill
  • (2020-02-10) Anthony Edge: Does exactly what I need. Handy for eliminating overwhelming/distracting advertising or inefficient layouts of regularly visited sites like news outlets.
  • (2019-05-29) Max Hetfeld: The update finally arrived.
  • (2019-02-13) Used to be good, now the JS part doesn't work anymore.
  • (2018-12-17) Ivan Bovin: Text field with Javascript is hidden. Has it done temporarily? .js-wrap { display: none; }
  • (2018-12-12) T C: Bad experience from the very beginning now it is even worse, it just does not work, all my styles have disappeared.
  • (2018-11-02) Hardy K.: It was my best addon, but since some time it is not possible to edit the JS. There is only a CSS field. I have no choice to remove it :(
  • (2018-10-29) Matt: The Javascript part broke, so half of the entire extension is essentially broken, rendering the entire thing useless.
  • (2018-09-05) Edoretan: Дякую за розширення! Крута штука. Якщо хтось не може вставляти яяваскрипт - https://chrome.google.com/webstore/detail/styler-classic/hbhkfnpodhdcaophahpkiflechaoddoi
  • (2018-04-06) S.A Mousavi (SAM): There is no priority over web site styles and your entered style skipped by chrome. You can see in the developer tools.
  • (2018-02-24) Mark Cameron-Smith: Doesn't work
  • (2017-10-15) Nicholas Brosius: Does not run scripts on page load like it once did. The toolbar icon must be clicked and a "RUN SCRIPT" button must also be clicked manually. Yes, even setting a script to run with window.onload or $(document).ready fails to run on page load. A minimum of two clicks are required to inject JS.
  • (2017-09-18) Andrei Surdu: Great extension, I like it so much. A real time saver. A companion that helps me change the style and UX of websites that are not so user friendly. !!! One request. Please implement a notification so we know that we already added some style or JS to a website. I think it will be enough to just change the icon color from black to green, for example. !!! Best regards.
  • (2017-09-01) Bartosz Dotryw: One feature I miss here: easy option to add external libs, just like in extension poakhlngfciodnhlhhgnaaelnpjljija
  • (2017-08-22) Antonino Samperi: I don't understand what Emoji have in common with CSS and Javascript. I want the old version of this plugin. This one doesn't execute scripts after page load.
  • (2017-08-07) Nicholas: Whole plugin changed, breaking everything. Creator is providing links to ANOTHER copy of the original plugin. Of course the other one doesn't load any styles from this one! He should have made the new plugin separately and left this one alone. I can't imagine how the creator thought it was a good idea to suddenly swap out the entire plugin on us. This is a fantastic example of "pulling the rug out from under people." It seems the creator thought he could also just shove another one under us. He is untrustworthy and should have his extensions pulled from the store.
  • (2017-08-05) Matthew Denton: New update broke my styles. Also the new marketing and outlook is childish. Emoji? Really? Because people who tinker with CSS and JS really love putting emojis on websites....
  • (2017-08-04) Ivailo Bardarov: Great extension!
  • (2017-08-02) Zack Schumann: It was cool, now it is effectively broken
  • (2017-08-01) Joel Jeske: New version is awful because it does not work. My styles are no longer applied. Why change it? It was working great before... Create a separate new extension, if you felt like using emoji's everywhere like a twelve year-old. Hate it.
  • (2017-08-01) Костя: Нафиг это обновление. теперь нифига не работает
  • (2017-07-31) Paul Fournier-Carey: No longer working for me - why break something, now chrome reports this as "injected" and therefore every property has to be marked as !important, which means nothing works... totally wiped out all my hard work and now have to start over
  • (2017-07-31) After update, CSS styler stopped working - something from css code is applied but something not. Removing and changing to something better.
  • (2017-07-31) Alex Ndefo: OK - everything ok, now ;-) Thanks... [[after update "to emojis" it is useless. All setting deleted.]]
  • (2017-07-31) Francisco Campillo Asensio: No se que pintan los emojis en esta extensión. Parece como si la extensión haya sido vendida a otra empresa y este empezando a destrozar el plugin con estupideces y (próximamente...) adware.
  • (2017-07-31) Aravind Goud: With the update there are some changes. Rebranding, need to add mandatory !important, etc. Can live with it. However the JS is now not auto executing. If I click run script, it works fine. However it is not auto execution which is exactly why I used this plugin in the first place. Please get it back or let me know what I should be doing.

  • (2023-04-11, v:6.1.1) April Fastek: Weird glitch with Google Docs
    Hey, so I've been having issues inserting a hyperlink in Google Docs, and today I disabled Styler during my troubleshooting process... and suddenly the problem with hyperlinks was solved. I'm on the most recent version of Google Chrome, on a fully updated Windows PC. This might be the weirdest bug I've ever seen, and I thought I'd let you know, in case it's not just me. I use your extension *constantly*, so I'll also take this opportunity to say thank you.
  • (2021-12-20, v:6.1.1) Kuria Ndungu: Styler for Firefox no longer available
    Hello. Styler is the fastest i've seen so far. It however is no longer for Firefox. can we get it back please?
  • (2021-07-14, v:6.1.1) Charly Empire: js inject gets reset upon refresh
    Running into this issue for some weeks now: When I copy/paste a new js script into Styler js box, it gets overwritten with the previous box content upon page reload. FYI: If I press the Run button directly after the copy/paste, it uses the new version of the js script. I am still below the 8000 char limit.
  • (2020-06-17, v:5.0.3) Josh Thomas: Bug Not Saving New Additions
    I have made several attempts to save my new CSS for a site and after page change or refresh STYLER reverts to the last saved data and loses all my new CSS :-(
  • (2018-08-03, v:3.18.0730) Santhoshkumar Anbalagan: Question?
    what purpose need to use this styler
  • (2018-07-31, v:3.18.0730) Alex Ndefo: Missing javascript field
    Missing javascript field
  • (2018-07-30, v:3.18.0730) Javascript
    No longer have the option to inject javascript, only css. Is this intended ?
  • (2018-06-25, v:3.18.0623) Louis Hong: Website with custom port doesn't run JS automatically
    i.e yourwebsite.com:8080 causes JavaScript to not run automatically.
  • (2018-05-14, v:3.18.0502) Tyson B: A list of pages that have edits
    I would like to be able to see a list of the pages I have edits on. Be able to click into and see the edits we have for those pages.
  • (2017-11-08, v:2.10) Phillip Bauer: URLs
    Can I somehow specify the URL that my custom styles are applied to?
  • (2017-11-07, v:2.10) Phillip Bauer: rewriting prototype
    I'm trying to rewrite the XMLHttpRequest.prototype to insert a hook but while my snippet works in the console, it does not do anything when injected with panda, although the code is being executed. Is that due to any known limitation of panda?
  • (2017-08-06, v:2.10) Prathamesh Gharat: It used to work perfectly before! Past tense!
    CSS is being injected in a weird way now, it creates multiple copies on each edit, this has a side effect, when you remove all of the CSS, the last style tag is applied. And seriously? Emojis? *sigh*
  • (2017-08-05, v:2.10) Rasmus Schultz: no longer works
    CSS is no longer applied on page load :-(
  • (2017-08-03, v:2.10) Nikhil Ratate: New update is awful
    When write my css in styler, its injecting code in dev-tools everytime code change, and injected style is not editable which was before. when I paste my css in styler it's taking it, but when i remove it, its not deleting it, I need to refresh page every time. plz roll back to previous version
