  • (2020-08-02) Anand Arokianathan: Amazing yet simple product just what i wanted i use it to condese all of the blogs to just the heading and picture and some content side by side such that i can go through the entire page in one go rather than scrolling it half of the time until i reach the end. The only issue i ave is there is no shortcut to disable and enable the custom style.
  • (2020-07-29) Gabriel Alejandro Zorrilla: Not working!
  • (2020-04-13) Кирилл Воробьёв: Полностью игнорирует сайты Яндекса. И что это за прогиб? Не то что рекламу, стиль текста заменить на удобоваримый нельзя - окно редактора просто не появляется. В остальном работает хорошо.
  • (2020-04-06) Govind Tiwari: Not working please check
  • (2020-03-26) Richard Simard: The extension requires jQuery dependency that it assumes is on the page. Should not require a script library to accomplish its goals. Many modern websites do not need jQuery due to the vast improvements made to vanilla JS. Please consider refactoring the extension to remove library dependencies.
  • (2020-03-12) Hussein AL-Mosawi: I downloaded it and was happy to try it but when clicking on it nothing happens! Because it doesn't work without jQuery
  • (2020-03-08) Milan Kragujevic: Does not work, shows a jQuery error in the console when trying to open the dialog.
  • (2020-02-04) Heck Fy: good extension, but i think that it loads too lately, and because of that it FOUCs on some sites
  • (2020-01-07) Sławek S.: Kompletnie nieintuicyjne, nieprzydatne bo zwyczajnie nie działa. No może działa, tylko nie mam pojęcia jak tego używać, bo zgodnie z instrukcją nie robi nic.
  • (2019-12-13) João Paulo: Muito bom e útil pra remover propagandas ADS. Very good and usefull to remove ADS
  • (2019-10-23) Lighty Ponce: Great extension tbh, wish it had autocomplete though
  • (2019-09-05) Miguel Sánchez Martín: It requires that the website uses jQuery but does not specify that requirement in the extension description
  • (2019-08-08) Nicolai Weitkemper: Funktionierte auf StackOverflow und YouTube, aber Reddit lässt sich nicht laden, solange die Erweiterung aktiviert ist.
  • (2019-07-20) Cesar Vidril: Throw a lot of error when button is pressed: Uncaught ReferenceError: jQuery is not defined.
  • (2019-06-17) David O'Donovan: It no longer works with google docs.
  • (2019-05-26) George Beckingham: Press the button, nothing happens. Is Google disabling extensions left and right?
  • (2019-05-19) mutiny lisa: Its code is relatively nice, the issue is, It doesnt work... I press the button on every website ive tried, waited up to 10 minutes, the UI never appears... Im very saddened now :(
  • (2019-05-08) Luky Wang: It's very cool, but version 2.2 not working on chrome 74.0.3729.131, it says "jQuery not found"
  • (2019-04-11) Damir Males: Rien ne se passe au clic sur l'icône
  • (2019-04-01) Doesn't work with optimised styles (many elements assigned to one atribute).
  • (2019-03-15) Mikhail Krug: Перестало работать в новом хроме
  • (2019-02-28) Cory Roberts: Not a very good plugin - when you resize the page to work on custom CSS on a resized Window, it resizes the editing box so small you can't read anything.
  • (2019-02-12) ElementalX7: Doesn't work. When I click on {CSS} icon on toolbar, nothing happend. The same in options. can't add website, change settings etc. The same on clear Chrome Dev.

  • (2020-09-16, v:2.2) Unslaved _: Differentiate domains and ports
    Currently the port is ignored. So the same css is applied to example.com as well as example.com:8080. It would be a great improvement if the port is considered too.
  • (2020-08-02, v:2.2) Ano Nym: Doesn't work on sites with framesets.
    When I click on the CSS button, nothing happens.
  • (2020-08-01, v:2.2) Robby Bennett: Hide website until the custom user CSS has loaded
    This would make the extension look a lot better. Basically, it could use Javascript to make the whole page be hidden or transparent, then it would wait until the page is loaded, then user CSS will be injected, then make the page visible again. Please add this as an option.
  • (2020-07-03, v:2.2) Ivan Tarazevich: CSS для всего браузера
    Добрый день! Данным расширением можно сделать свой css который будет всегда подгружаться браузер при просмотре любой страницы? В общем нужно чтобы мой css всегда сидел в бразуре. Или предусмотреть в вашем расширении переключатель который будет включать так сказать "сквозной" режим работы css введенного пользвоателем.
  • (2020-06-09, v:2.2) FleepyALT: Live file updates
    Hello, I'd like to suggest an option where you can input a local file on your filesystem to a custom css file, and as you save it in your editor, it will update live on the page you are editing
  • (2020-03-23, v:2.2) em: Images won't load
    Hi, I am using User CSS to create a custom theme for a website. However, whenever I visit the website, none of the images I use will load unless I open the CSS editor. I am using them in this manner: background-image: url("https://i.postimg.cc/Z5B2yQ0R/tancssfolder.png"); Please advise? Love the extension btw!
  • (2020-02-13, v:2.2) Michael: Keyboard shortcuts
    I'd like to be able to turn on/off the extension's css effects with my keyboard. Is this possible?
  • (2019-12-17, v:2.2) Элина Айрапетян: не работает
    не нажимается и не открыват панель
  • (2019-12-03, v:2.2) Dimiter Simov: It does not work
    I was not able to start it on Chrome Version 78.0.3904.108.
  • (2019-10-26, v:2.2) Marwan Abdessalem: Make site's styles unique by domain as well as the port number
    Styles that are set for the site http://localhost:3000/ should be accessible by http://localhost:8000/ or http://localhost/
  • (2019-06-20, v:2.2) Noel Németh: Less CSS support
    It would be good if it would support Less CSS
  • (2019-05-16, v:2.2) Arthur Mougin: jquery error
    hi, clicking on the app icon show a warning saying that jquery dont exist. That might be the reason why the app doesnt work
  • (2019-05-11, v:2.2) Muhamad Basyir Bin Mat Nawi: How to export configuration data?

  • (2019-02-22, v:2.2) Mihai Stanescu: Automatically activate the extension
    Hi, Is it possible to automatically activate the extension? I have to click the thing all the time
  • (2018-11-28, v:2.2) jQuery is not defined error
    I'd suggest adding a fallback to '$' if jQuery wan't found. And perhaps for future versions add a jQuery dependency for the plugin, so it can work on any website, regardless of what technologies they are built on Thanks!
  • (2018-11-11, v:2.2) Vlad Svoka: CSS inside iframes are not affected
    So I have a site, it has iframe of itself <iframe src="/api/v2/page"></iframe> Styles are not applied inside of it. Problem is generic. I want to customize how iframes with specific srcs are displayed
  • (2018-07-01, v:2.2) Matteo Chiari: Not working as of 1/7/2018
    CSS Editor does not open on any page
  • (2018-01-29, v:2.2) Lance E Sloan: simpler active toggle?
    One change I'd like to see is that a click on the extension's toolbar icon should toggle the "on/off" state. A different combination (like control-click or shift-click) could open the editor panel instead.
  • (2018-01-16, v:2.2) Cody Nichols: iframe
    On my university's LMS, they use iframes for a lot of things. If I look at the source i can change css properties of the elements inside of these iFrames. But i can't seem to get the User CSS to be able to select the objects inside of them. Is there anyway around this?
