Temporary Containers Firefox Add-on

Detailed information about the Add-on can be found on AMO. There's also this long-form article and the project wiki.

Development

Requirements

• Clone the repository
• npm install
• npm install -g web-ext

Run in Firefox

• web-ext run -s src
  • starts the default system Firefox, loads the Add-on and watches for changes
  • append -p profilename to start Firefox with a different profile

or

• Open about:debugging and Load Temporary Add-on which is located in the src directory

Check about:debugging and click Debug under Temporary Container to see the console.

Run the tests

• Once: npm test - this also shows a coverage summary and generates a detailed report in the coverage directory
• Watcher: npm run test-watch

Release

AMO and GitHub

• Bump manifest version
• npm run build
• Upload zip web-ext-artifact to AMO
• Download published AMO xpi
• Create and publish GitHub release with AMO xpi
• Add new version with link to the GitHub xpi to updates.json
• Commit and push

Pre-Release on GitHub

• Set API key/secret env vars
• Bump manifest version as beta
• Commit
• npm run build-sign (Adds update_url to manifest and reverts with git checkout -- manifest.json)
• Create and publish GitHub pre-release with generated xpi web-ext-artifact
• Add new version with link to GitHub xpi to updates.json
• Commit and push

Libraries

The included SemanticUI and its dependency jQuery are awesome and are used for the preferences & popup UI, though not for the background and content script.

Limitations

• Disabled in "Private Windows" since Firefox doesn't support it
• Android Support is not possible since Firefox doesn't support it
• Mouse Clicks:
  • In combination with Multi-Account Containers: Opening the same link multiple times in quick succession will probably not work as expected when the site is set to "Always open in $Container".
  • Doesn't work on addons.mozilla.org (Firefox prevents content scripts there). If you assign addons.mozilla.org to "Always open in" with Multi-Account Containers you will see unexpected behavior since Add-ons, including Multi-Account Containers, are not allowed to block requests to addons.mozilla.org.
• In Automatic Mode:
  • "No Container" Tab (Alt+N) and Window (Shift+Alt+C) must open about:blank due to Firefox API limitations and thus the address bar can't get focus when opening a new "No Container" tab.
