Like the options, but I had to uninstall it due to making Firefox 'hang-up' and slowing down pages. Took forever to figure out it was this particular app. now I have no issues. Fix that and I'd love to use it again.

Love this in theory, but in practice, it's incredibly slow, and bogs down my browser impossibly. I do hope this improves, as I'd love to keep using it!

this is completely the best webpage customizer! or is it the only one?! I don't know but I looked for others and never found one! seems like there are tons of dark themes out there but if you want to use your own color ideas then you best get this addon! and it's so easy to use a puling infant could do it! developer thanks for giving we users a choice besides black for an overall webpage theme! every end-using addon DLer has ideas to improve on addons because ideas are like %&#*(*%s, everyone has them and I'm no different. my idea is add a function so the user can import/use his own .jpeg image choice for the background because I sure want to use one of the Hubble Deep Field images as my background! otherwise, touche! a perfect addon and a must have! Thanks for making my web experience much better.

Отличное расширение! Стиль изменяется за несколько кликов, страницы сохраняются со всеми правками - именно то, что искал!

What the heck is the developer thinking?
No one will try an add-on this way.
Poor description is a general problem with newly published add-ons!
After revision: ...now it looks much better!
