I'm on a MacBook. I checked under Firefox, Preferences, Privacy and Security, Certificates, View certificates. Nelligan is the one I need. I'll attach some screen shots. Had nothing but headaches with Firefox 64.0.2. Crashes have decreased, but still a few times every day. Just about ready to move to another browser.

I can access my account fine on Safari

I can't find anything about this specific certificate block, so I don't know how you ended up with this "ville.montreal.qc.ca" block.


Try to rename the cert9.db (cert9.db.old) file and remove the previously used cert8.db file in the Firefox profile folder with Firefox closed to remove intermediate certificates and exceptions that Firefox has stored. Note that current Firefox releases use a cert9.db SQLite database file.

If that has helped to solve the problem then you can remove the renamed cert9.db.old file. Otherwise you can undo the rename and restore cert9.db.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Thanks for the effort. I only succeeded in losing my bookmarks. I finally got them back. I have about four profiles now. I'll just use Safari for the library. Firefox is a nightmare.
