Tab Cap enforces a hard limit on the number of tabs you can have open at once. When you try to open a tab past your limit, it's immediately closed and a notification reminds you to close one first — no silent behaviour, no guessing why a tab didn't open.
Features: - Set any limit from 1 to 200 tabs - Pinned tabs are excluded from the count — they're tools, not clutter - Per-window mode: enforce the limit on each window independently instead of globally - Live toolbar badge shows your current tab count at all times, turning red when you hit the limit - Tracks how many tabs you've blocked today - Adapts automatically to your Firefox theme — light, dark, or any custom theme - Keyboard shortcut: Alt+Shift+T (rebindable in Add-ons Manager)
Tab Cap is useful if you find yourself with dozens of tabs open and want a firm boundary to work within. The limit is yours to set and change at any time from the toolbar popup.
