Bookmarks and History, GONE!
As of yesterday, Oct. 14, 2025, everything in my Firefox Bookmarks and History is gone. This is the message displayed: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I have tried to recover them by different suggested means, but it would appear there is NOTHING to recover. Everything in Bookmarks says EMPTY, and I can no longer save any new Bookmarks, it just not allowed. How and why did this happen, and what am I supposed to do? I had hundreds of things Bookmarked, many of them were important to how I run my business, and now are seemingly all gone. This is very upsetting and would appreciate Mozilla getting this straighten out. I need and explanation and resolution.

Thanks for the response, but there is no other profile. There is nothing left of my Bookmarks, anywhere.
