⭐ FF Ultima Catppuccin-Mocha Edition by Draff (@ItsLogic) (promo)

Warning

This update is ONLY for Firefox Version 131

It's happening! Firefox developers have officially introduced Vertical Tabs!

You may or may not have noticed, but many custom themes that target tabs have broken recently. This is because - as of Firefox version 131, Firefox has made their own vertical tabs implementation. Firefox's implementation is missing a lot, the spacing is extreme.. auto-hiding tabs isn't a thing, etc, etc, but most importantly.. This forces a bit of a reset onto the FF Ultima theme.

As the developers continue to make progress, the theme will only improve, while restoring many of the lost features. With all of that said...

Time to delete the old theme
Re-install FF Ultima here
Use the new user.js file
