Great extension I've used for a long time across a lot of different sites. Here recently there are some issues with Arc Browser, though. It's still applying my custom styles/scripts but for some reason when I click the extension it won't show me any of the scripts I have saved nor will the extension tab that opens up and shows you all your rules.
Doing what it should do, injecting custom JS/CSS without hiccup.
Doesnt work very well, buggy
very good, i had personal preferences for my team dev so this was very useful
Works fine.
Nice. But have to manually sync with cloud. Need option to autosync.
никаких проблем не было за меня использования надеюсь не загнется
Setting css is not working. Not sure if this plugin works at all. Custom CSS by Denis does work as expected
It doesn't rlly work for me, it doesn't affect the websites at all, pls update css
Indispensable pour automatiser et supprimer les désagréments cybernétiques du quotidien. Je ne peux plus m'en passer !
