This is more configurable, you can set theme color text in when web is ligth or dark, but the last update is a little bit old and slower than Adaptive Tab Bar Colour

Download VivaldiFox from Mozilla add-ons

Uncomment @importurl('components/vivaldifox.css'); in userchrome.css

Comment @import url('components/adaptative_tab_bar_color.css'); in userchrome.css

Configure Vivaldifox as the images you can find in this repository folder in Minimal-VivaldiFox-Theme/VivaldiFox config screenshots/

This is less configurable, you can NOT set theme color text in when web is ligth or dark ()It take firefox default color black/white). But it was updated in 10 de jul. de 2023 (at the moment to write this), can update theme color when you scroll down the website and is a little bit faster than VivaldiFox.

2. Install the extra files it asks you to install. And run the program.
3. At the bottom left corner press Add Rule -> Add Process Rule, type firefox -> add.
4. On the left panel select and open firefox section. Change Mica to Acrilyc for better blur effect.
5. Dont forget to uncomment @importurl('components/mica_support.css'); from userChrome.css

Test it in Win11 Test it in Manjaro KDE(maybe need ForceBlur in kwin scripts) [Firefox 117 broke transparencies in linux (tabbar border is not transparent). Fix WIP]
