Firefox: форум сообщества

Hoping to restore Firefox with tabs that existed yesterday evening in two separate windows but were inadvertently lost due to mishitting “Restore prior sessions” and then compounding it by thinking recent tabs were being retrieved but were replaced with older unneeded tabs instead. Submitted again to correct retrieval from incorrect (today) to yesterday 11/8/26 (correct)

Hoping to restore Firefox with tabs that existed yesterday evening in two separate windows but were inadvertently lost due to mishitting “Restore prior sessions” and then compounding it by thinking recent tabs were being retrieved but were replaced with older unneeded tabs instead.

My bookmarks and passwords have again been deleted. I can restore the bookmarks but not the passwords. Why is this happening over and over again? Really getting tired of this happening.

On a relatively new laptop (bought because my old one cant upgrade to Win11) I frequently lose my Firefox passwords and bookmarks. I reinstate them from saved files, but it is inconvenient and shouldn't happen (at least one a week). I am beginning to wonder if periodic clean up (in the background) by Iolo's system mechanic may be causing it. Has this been flagged up by anyone?

the address on all of my bookmarks has been changed to the 1 same bookmark location I last used.?????? How do I get back all of my bookmarks back with the correct location without retyping each one individually????

Firefox suddenly became an entirely different browser without me doing anything. It wasn't loading any web pages so I restarted it and it was completely different, and not for the better. All my bookmarks are gone. What the hell did you do?

My bookmarks and settings are so messed up. I am frustrated as I am working on a project, and the browser no longer has the functionality it had before. I am considering switching to another browser in the next couple of days unless it is repaired.

This is the 2nd time in a month that I got up to go online and Firefox was gone, disappeared. Had to re-download and start over from scratch, no saved bookmarks or pictures, all gone. What is going on, and how to restore my original Firefox with all my info? Is it possible now that I have downloaded yet again Firefox 11? I supposedly imported fro google account, yet everything is gone? What should i do? Thx

Hi Mozilla Support,

I made a boo boo, was half asleep trying to shut down and wanted to quickly save a set of browser tabs to come back to later, so "attempted" to create a folder to save within a nested structure in my bookmarks library (using Ctrl+Shift+O editor). I right clicked and intended to hit 'f' for new folder in the structure, hit 'd' instead (delete). This was on an upper level folder structure of thousands (10's of thousands....?) of bookmarks.

Realised my half asleep mistake and doubled down! Hit Ctrl+Z to undo changes.

Well, I guess FF was struggling to process all of the changes, then got confused with the undo, and broke without performing either... F**K. But ok, I will just restore from a backup, I have those setup.

So I went to 'Import/Backup -> Restore, and picked the latest date. Okayed the warning and waited. It failed, gracelessly, by deleting all my bookmarks, then errored. "Unable to process the backup file." Now I can't restore any of the restore files in the list. The latest one looks broken with almost no data, but all of the earlier ones are there, they exist in the folder structure under AppData, say they have 30,000+ bookmarks, and are all around the 20MB size.

None of these restore.

My only hard HTML backup is from early in the year, March, and that is very old in my activity levels.

Also, why are all of the json files failing?

I've since restarted my PC, slept and come back to the problem awake. Still same problems.

I have gone as far as using the 'Refresh' technique in the uninstall options, and despite everything else coming back from scratch, I still cannot restore my json backup files. They all give the same warning, delete any bookmarks I have added and then error with, "Unable to process the backup file."

Is this something that has happened before? I get I screwed something up, but what could be preventing this from restoring? Are all of the json files now poisoned somehow?

Do I have to do a full uninstall and reinstall and try again? And if that fails, what are my options?

I have backups for a reason, this very reason in fact, so that when I error, I don't delete my life...

Would love some guidance on this, if there is a way to check .json integrity, or anything else pertinent I might have missed, I would appreciate a poke in the right direction.
