Question Warning avoid updating firefox, new update uses new profile system loses your stored profile

[danger007]

I just ran firefox which did one update, says profile is being changed, I saved like it said, then 20 minutes later restarted says updating again and this time all of my data (passwords, history, bookmarks) are gone.

DO NOT USE FIREFOX at this time.

So far no such issues with my Firefox.

What version? I'm on version 67.0 (64-bit) and it's fine for me. When/if it asked you to "refresh" Firefox during the update, did you choose yes? If so, that's likely the problem. I almost selected yes also. Confusing wording.

See if this helps:
