Tab Shortcuts од PierreBou91

Tab Shortcuts

Shows the tab shortcut number in each tab title, like ⌘1, ⌘2, etc.

What it does

• Prefixes each tab title with its shortcut number.
• Matches Firefox's shortcut order and skips collapsed tab groups.
• Updates automatically when tabs move, open, or close.

Limitations

• Firefox maps 1 through 8 to the first eight tabs, and 9 to the last
  tab. If there are more than 9 tabs, the middle tabs won't show a number.
• Internal pages (about:*, moz-extension:*, etc.) cannot be modified, so no
  shortcut number is shown there.
• On non-macOS platforms the prefix uses # instead of ⌘.
• Only tested on MacOs for the moment.

Permissions

• tabs: read the tab order and listen for tab changes.
• tabGroups: detect collapsed tab groups so they don't count.
• <all_urls>: inject the content script to update tab titles on web pages.

Most of this extension was developped by GPT-5.2 Codex using Cursor. Except for a few tweaks and this readme, I only reviewed the code.
