Hi, there.

After performing the most recent Firefox update, I was greeted with the "create a new profile prompt", rather than having it open my old one. When going to "about:profiles", ALL FILES in the Root Directory of my old, default profile have the same date as the update, or after. Not a single file is older than that and all my history and bookmarks are gone. The option "Restore Previous Session" was not shown after the update.

PLEASE HELP!!

Thank you.

PS: This happened on a Macbook Pro. All other profiles are the same as they were before the update, having kept all history and bookmarks.

Bookmarks and History not functioning.

This is the message I get when I try to access my Bookmarks: "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 already tried to find out from Microsoft if their latest reinstallation of Office Professional could have caused the problem. They say they have nothing to do with Firefox. How can I get my Bookmarks and History back?

I just updated to the latest Firefox. All my history, bookmarks, extensions are now gone. I do not seem to be able to get them back. My old version of Firefox is not available. When I ask to update from a prior browser, the drop down selection does not give me my prior version of Firefox. Help!

I can't bring back a session even though I did all of the steps to bring it back.

I think that this recent update removed all of my tabs and tab windows, it has done this before and I don't understand why, I have the old update session file still (The 11/11/2025 One) and I tried to use that one to bring the tabs back by putting the file in the sessionstore-backup folder with no other file in it, but they didn't come back. I am genuinely confused as to why it doesn't work, I have renamed and deleted sessionstore.jsonzl4 files but it still comes up as a new session.

I recently bough a new computer and transferred all my data, passwords and bookmarks to it. Each time I opened my mozilla browser I was encouraged to create a profile , but each time I just continued without creating a profile. Finally today I was not given an option to proceed without creating a profile so I did. But now all my passwords and bookmarks have disappeared. When I try to find them I am advised to load my previous profile but this is not an option the only profile I have is the one I just created with the missing data. Can you please tell me where the appropiate files are stored and how can I recover them. Thanks
