Assign a bookmark to a container

Warning: This workaround needs an add-on that is not actively monitored for security by Mozilla. Make sure you trust it before installing.

  1. Install Open URL in Container addon.
  2. Open bookmark manager by clicking on Main menu > Bookmarks > Manage bookmarks
  3. Create a new bookmark by clicking on Organize > Add bookmark...
  4. Enter a name for the new bookmark (e.g. Containerize a Bookmark)
  5. Enter the following code snippet in URL:
javascript:(function(c,u){c&&(c=c.trim())&&(u=prompt('URL?',location))&&(u=u.trim())&&prompt('Contained URL to copy and bookmark:','ext+container:name='+encodeURIComponent(c)+'&url='+encodeURIComponent(u))})(prompt('Container name?','Personal'))
  1. Add the bookmark in a place where you can click on it like the Bookmarks toolbar (Ctrl + B). Note that you can't launch a bookmarklet by searching for it in the address bar.
  2. Go to the site you want to run in a specific container.
  3. Click the bookmarklet you created, pick the container name and copy the link.
  4. Create or edit some existing bookmark to set it to this link.
