I'm trying to use Firefox as my default browser, but it keeps importing bookmarks. They look like duplicates but there is no way to stop. Should I delete and reinstall? I don't need to import bookmarks

Chosen solution

When do these bookmarks show up? When you start Firefox? During the day?

Are you using sync? If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.


Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
