FF-Better-Tabs

Small userChrome.css file to make the tab close button work better in Firefox

This is a very minimal file with only a few rules, so it should be compatible with all Firefox versions that use Proton UI (>= 89.0) and is unlikely to get broken by updates.

Tweaks

• The tab close button is hidden by default
• It shows up when you hover over a tab
• You can enable always showing the close button on active tabs
• The left side separator has been removed
• The extra padding on the left on unmaximized windows is gone
• No extra space between pinned and normal tabs

Screenshots

If you want to always have a close button visible on the active tab, you can uncomment the last rule:
