Assigning containers to bookmarks

Sometimes you have sites you want to open across different containers (e.g. Outlook) and it's a pain to do "Container on bookmark dropdown menu" every time.

If you have the Firefox plugin "Open external links in a container" installed you can assign bookmarks to containers by putting the following in the URL field for a bookmark:

ext+container:name=Personal&url=https://outlook.office.com/mail/inbox

Where container:name is the name of your container and url is the URL you wish to open.

With this approach you can have multiple bookmarks for the same site with each opening in a different container.

Don't close window when last tab closed

  • Accept the warning message
  • Search for "browser.tabs.closeWindowWithLastTab"
  • Double-click to set it to "false"

troubleshooting

Troubleshoot mode

Troubleshoot Mode runs Firefox with some features and customizations disabled (see below for details). If you're having a problem in Firefox that does not occur in Troubleshoot Mode, the cause of the problem is one of the disabled items.

Refresh Firefox

If you're having problems with Firefox, refreshing may help by restoring the browser to its default state while saving your essential information, like bookmarks and passwords.

Firefox will save these items:

  • Bookmarks
  • Browsing and download history
  • Passwords
  • Cookies
  • Web form auto-fill information
  • Personal dictionary

These items and settings will be removed:
