Briliant, really useful extension. Thanks for making this available. I have a need to modify text on certain websites because grey and other low contrast text gives me eyestrain so I need to change the text colour to black, this extension lets me do this on a per site basis which is tremendously useful to me. Just one query, though. Certain websites seem impervious to CSS injection with this extension. Ebay.co.uk is one such, nothing I try seems to have any effect on that site. I fixed Ebay with a bit of javascript instead but I am curious as to why some sites cannot be modified by injected CSS.
Теперь я пишу себе "расширения" внутри этого расширения под каждый сайт, это, чёрт побери, великолепно!
Really love this extension. Just wish the data is synced with my account. Also, wish it supports scss as well.
Love It
Tried maybe 10 other plugins, this one just works! I spent maybe 30 minutes installing and then removing 5-8 others to no avail. Not sure what was going on but this plugin just worked and was intuitive. Thanks much for it.
Legjobb adblock :D
Отличный плагин. Именно такой и искал!
Love it! I use it all the time. One of those things that makes browsing frequently browsed sites better.
Super quick ans easy to set up. Used to use tampermonkey until I saw this. This is so much neater
Супер расширение) То что искал для внедрения своих jq скриптов на свои страницы :3
