Today my pinned apps, tab groups and history ALL disappeared, and my settings were changed to "Clear history when Firefox closes." How can this happen!?

I've had several pinned apps, tab groups etc that always reappeared when I closed and opened Firefox. I always had history stored without a problem.

Today I opened Firefox, and my pinned apps, tab groups, and history were all gone, and the option to Clear history when Firefox closed was checked. I did NOT do that. How could that happen? I definitely need to avoid this happening again!!

Please help! Thanks!

If you didn't do that yourself and nobody else has used the computer then an extension may have made that change.

I see in your list that you have some Norton extensions (toolbars) installed that could cause it, but others may do this as well.
