Quickly open your Gmail inbox from the Firefox toolbar.

✅ Supports multiple Google accounts: Right-click the button to switch between Gmail accounts like /u/0, /u/1, etc.
✅ No tracking, no background usage
✅ Faster than bookmarks and more convenient than pinned tabs

Whether you manage work and personal Gmail or just want instant access to your inbox, this add-on saves time every day.

Works great with Firefox Containers and Google Account Switching.
