I love it very much but I have a problem it works on chrome perfectly and also on android Kiwi Browser and but now it doesn't work on android Kiwi Browser I hope you to solve this problem please
Einfach das wie ich mir solch ein Tool immer vorgestellt hatte!
10/10
Great extension, this was an absolute life safer for me. We have a code review tool that paints the background of newly added files with bright green and makes it impossible to read the code to review it without having your eyes bleed. I used this to override the CSS and get rid of that green.
Love
Спасибо, перепробовал много подобных, этот работает четко. Использовал для изменения копирования цитат из Библии (стандартно просто добавляется ссылка на сайт, а я сделал преобразование текста в одну строку и добавлением адреса из Библии.
Love the extension and will gladly change this to a 5* review but leaving 1* for now to draw attention to a critical bug whereby disabled and/or old versions of scripts are being run. Issue started occurring about 24-48 hours ago.
Só estou tentando adicionar uma lib de CSS prefixer para deixar a extensão completa. Ainda não consegui, mas é a melhor extensão que existe.
It's great, but there's an issue of it running scripts that aren't enabled rn. I have around 15 scripts, and one of them is running while not being enabled.
Great plugin! Tried many similar ones, but this one has the cleanest interface and works best. One thing I really miss is the option to run scripts on demand! For exampler by opening a plugin dropdown and clicking "Run" button beside the script name. Do you have something like that in plan for the future version?
