Firefox Community Forum

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

I have no idea what happened, but i was changing settings on my PC and suddenly i was logged out and all my browser data, bookmarks, passwords etc were gone. I dont know if i clicked the wrong button or what but everything is gone. I still have my data on my phone, and can access my passwords and such but I dont know how to get the browser data from my phone onto my PC

Please, I have many important passwords and bookmarks that I need to be able to recover.

I had a lot of tabs open in Firefox, and they always stayed there even after restarting my PC. But suddenly, all of my tabs disappeared, and I can’t recover them using “Recently Closed Tabs.” Can I get them back?

Upon restarting my laptop earlier today, I realized that ALL my Firefox bookmarks have disappeared into thin air. Gone (or, rather, "empty") is my bookmarks toolbar, and my bookmark menu, and everything else. What to do? Thank you.

Thank you to JBR, who posted an answer to your question "All bookmarks disappeared. I found my json backup files. How can I import this file into Mz, now that it has created a new, dysfunctional 'profile' ??"

Unfortunately, the reply does NOT help. I have been through all the posted replies to missing bookmarks, and NONE help.

On my own, I found the bookmark backup files, and noticed that ONLY the newly imposed profile has any of those files. So I have access to those .json files, but my question remains: HOW to get that file back into Mz????? None of the posted replies, including your own, even pose this question. In short, after the newest Mz update, the 'restore' or 'import' bookmarks function(s) DO NOT WORK AT ALL!!!

I am sorry, but this problem appears to have been caused by Mz and its latest update; it's for Mz to fix, ASAP !!!

Perhaps I should mention, I'm far from computer- or OS-illiteracy, and am getting ever more fed up with software 'developers' who keep adding more bells and whistles which degrade functionality. I'm a long-standing touch-typist and am significantly faster than any OS's directory trees. Forget AI, I've no need of it.

With sincere best wishes, despite my current frustrations,

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

I was trying to Sort by Name, but hit Delete, because the right-click menu presentation shifted. No worries, Ctrl Z should undo on PC. Nope. Now I'm learning the only restore is through JSTOR/backup. I don't want to restore a previous state of operation. I want to un-Delete a folder. Is that a feature somewhere, somehow?

And secondly, can I force confirmation for all future folder deletions?

I use Firefox under Fedora (I'm two OS versions behind, must upgrade soon). I open very many tabs each day then work through them, theoretically every day, in practice they accumulate and I deal with them when I can. I rely on the tabs loading correctly on restart, but today they didn't, instead the set of tabs that were opened a few days ago loaded, and I lost everything I had done since then. Is there a way to retrieve the tabs that were opened just before this happened, ie around 15-20 hours ago? Ideally, again, I would merge them with the current ones, but reopening the old ones would take much much longer than reopening the new ones. Thank you for any advice.

The power went out in my area last night and When I turned my computer on this morning and opened Firefox, all my bookmarks are gone! It says the bookmark file is empty? I had many bookmarks that I use daily. How do I retrieve all my bookmarks I had in my Firefox account? Can someone help? Thank you.
