A switch for Firefox's native sidebar (bookmarks, history, etc). It's a slim vertical button on left of main content. Compatible with vertical tabs.
Replace the legacy addon All in One Sidebar. You can open sidebar by clicking edge of screen.
- Left click: toggle sidebar page (bookmark)
- Right click: toggle sidebar launcher / toggle vertical tabs width
- Middle click: toggle vertical tabs
This is a Firefox userChrome JS script.
Tested on Firefox 140.
This repo only contains the specific function, doesn't contain the code to enable userchrome scripts.
