I'm seeing an upper case white "P" and lower case white "f" inside a red box/square, in the left margin beside a bookmark. What does it mean? The specific website I bookmarked is Telus Mobility, My Telus. All other bookmarks look normal, with their own unique icons. "Possible fake"? Don't know how to screenshot it, so please don't ask.

Does that icon appear in the same space where you normally see the website favicon ? Do you recognize this icon from another bookmark or history visit ?


This could be a problem with favicons.sqlite in the Firefox profile folder.

If you use Sync, best is to disconnect Sync temporarily during troubleshooting.

This could be a problem with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

  • use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page

If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder with Firefox closed. Firefox will rebuild places.sqlite and restore the bookmarks from the most recent JSON backup in the bookmarkbackups folder.

  • keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
  • you lose the history when a new places.sqlite is created

You may have to restore an older bookmarks backup in the bookmarkbackups folder via the Bookmarks Manager (Library).
