Крутое расширение!

Best browser extension I've ever used! Beautiful! Works great! A lot of choices but easy. Can be time consuming depending on amount of customization's you want to make. I love customizing and detail this extension almost has it all. I do wish an element could be added for an image/wallpaper to the background and a microphone icon/voice search in Firefox search bar so that I could used Firefox Default Homepage again. Thanks

Amazing addon

Easy use, good plugin.

I just love it

Simple addon. It's very intuitive and easy to use.
For those who complain about the impossibility to save your customonization (for another device or anything else) , it's because of security. It's quite complicated for new users to deal with that.
BUT THERE IS AN ALTERNATIVE : just save or bookmark the URL when you set your colors (it changes after ANY modification you make). After that, you just need to revisit your saved URL to reinstall your custom colors.

Excellent add-on. People with color perception issues can fine tune FF to their needs.
