Modern Theme All4You توسط

This theme makes your Firefox enjoyable and is used around the globe!

The fresh, modern and timeless design stays in the background so you can focus on your work. This makes it the better version of boring Dark Mode.

No more eyestrain and no headache anymore, but be aware of bright designed websites, they will drive you nuts.

If you are used to classic shell design or simply dislike orange you can switch to the Modern Theme Green.
