Firefox extension for managing tabs and bookmarks in sidebar.

addons.mozilla.org (v4.10.2): Release page | Addon page | Install (reviewed by Mozilla)
github.com (v5.0.0rc5): Release page | Install

Sidebery is a highly configurable sidebar with panels of different types. Some of the key features:

• Vertical tabs panels with tree or flat layout
• Bookmarks panels
• History panel
• Search in panels
• Customizable context menu
• Customizable styles
• Snapshots (saved windows/panels/tabs)
• ...and more

Firefox doesn't allow addons to hide native tabs, so you have two options:

• You know CSS and can maintain it after Firefox updates: Use userChrome.css hack
• Otherwise: Use floorp (github)
  • Install Sidebery
  • In Floorp settings set:
    • Design >> Tab Bar Style >> Horizontal Tab Bar
    • Design >> Tab Bar >> Hide tabs on Horizontal Tab Bar
    • [To hide the sidebar header] Design >> Tab Bar Style >> Collapse Tree Style Tab
    • [To auto-hide sidebar] Use "Lepton UI" and check its settings

Prerequisites: latest LTS Node.js version

1. Install dependencies: npm install

After creating the Add-on archive, you can then use the version in Firefox as follows:

1. Open Firefox
2. Go to about:debugging
3. Go to "This Firefox"
4. At "Temporary Extensions" click on "Load Temporary Add-on..."
5. Select the .zip file in the dist directory.
6. Close the settings tab
7. Your Firefox now always runs with the development version
8. For updating: Repeat all steps.

Install dependencies: npm install
Build and watch for changes: npm run dev
Run browser with Add-on: npm run dev.run -- <firefox-executable>

You can donate to this project, which will motivate me to answer questions, fix reported bugs, implement requested features and generally will speed up development process. Thank you.
