  • (2019-12-12) Derghi Arrinde: Hmm, it seems to include its own jquery file? Seems to rely on jquery a lot, even in the css/js injection part of the script. Uninstalled. Devs, please let me know if I am wrong.

  • (2019-08-06) Möckli Söckli: There is a website with a chat where the own chat bubble has a background color of some kind of light yelow-brownish and white font. Very ugly and not good to read. I used this plugin to change this. Well it works. It does exactly what it should. So i have to say I love this extension.
  • (2019-08-01) Dima: Добрый день! Есть ли возможность заинжектить CSS после прогрузки страницы? Т.к. сайт на котором я хочу поменять CSS прогружается блоками и нужные мне блоки загружаются через некоторое время и стили которые я внедряю не применяются. Возможно я делаю что то не так)

  • (2019-12-03, v:1.2.6) Leighton Duffin: jQuery class selector not running
    Having a problem where my jQuery class selector doesn't run. If I run the following line in the Chrome's console it executes as expected: $(".article_header").css("display", "none"); But if I included this in User JavaScript and CSS it never runs. I can select html elements but doesn't seem to select classes. Am I doing something wrong?

  • (2019-08-22, v:1.2.6) Geoff Davids: jQuery library not being included
    I have tried using jQuery with JS augmentation to websites, but nothing works and in the console I just get the error message "jQuery not defined" or "$ not defined" depending on which way I try to load it. I have tried removing and re-adding the library, and changing it from the local loading to loading from Google's CDN, but to no avail. Am I doing something wrong? Apart from this your extension is fantastic and a joy to use, and I'd love to get to the bottom of this!
  • (2019-08-13, v:1.2.6) Nick M: It doesn't open with the first click
    Very good work. Congratulations. I have a problem. When I right-click to open the application, it starts, it appears to open but immediately the content disappears. If I'm lucky, it can open the second, third, etc time. Otherwise I have to repeat the clicks too many (10 or 15 or 20) times. Because this "User JavaScript and CSS" is as good as you designed it, it's a shame not to fix it. Can you tell me what to do? My computer is running Win7 and Chrome is up to date. Thank you very much, I look forward to your news.
