with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

I recently bought an new HP Win 11 PC to replace my current Win 10 machine. Running latest FF 144.0.2 on both. How do I transfer my complete FF profile (bookmarks, bookmark bar, login data, EVERYTHING) to the new PC? Want the new install to be an exact functional copy.

THANKS!

For some reason all of my bookmarks are gone. I have tried all the suggested fixes and it's still not working. Don't know where they went but I would sure like to have them back. Plus, now when I try to bookmark a page its not accepting it. :(

Yesterday I got a prompt saying there was an update available for download. Today when restarting my laptop and opening Firefox ALL of my bookmarks are missing!!! My bookmark toolbar is also empty. Where did all of this important stuff go? Please help me restore this my information asap. I am freaking out!

Dear Support,

today i recognize that my bookmarks are gone and i cant find any backup data or something else. First of all i restart morzilla. Then i restart my windows 11. still gone so i load a windows backup from yesterday. nothing change so i reinstall Morzilla but its still gone.

Is there anything else i can do ?

When I allowed your latest update to happen ALL MY BOOKMARKS WENT AWAY! Can you restore them for me? I am 95 years old and don't do this stuff well. Otherwise, tell me how and I will try.

Hallo mein firefox hatte pobleme weshalb ich es neu installiren musste seidem werden mir nicht mehr die passworter und lesezeichen angezeigt ich wollte fragen ob sie mir dabei helfen können.

Problem w/ Clippings again today. Prior: https://bugzilla.mozilla.org/show_bug.cgi?id=2045930

Windows 10 - Pro Lenovo T490 ( Lenovo LTD installed firmware update 6/19 & 17/26 (respectively - 1st time I've EVER seen this): 1.0.0.28 & 1.0.0.85

An icon is missing from my desktop which I normally use to open FF. I have noticed issues when NOT using this icon previously - like there is a different version or ID attached - I need to get this back. Data Loss (Clippings) / Again !! - I'm not sure who is at fault. When I display Settings - I notice a HUGE difference in that there is NO General tab (attached) as there was when I reported this (similar to me) issue last 2 weeks ago (see original problem report link).

When I use Recovery: I have a file displayed: Location C:\Users\pc\Desktop\Old Firefox Data\wu6w9pz8.default-release\sessionstore-backups Last modified 6/8/2026, 8:07 PM (3rd time in this doesn't show - right after copying the filename !~)

I believe I need to use this as my production / live version & need instructions on how to recover / restore this. I have NOT YET used Windows Recovery (but I will look at it) - Microsoft Visual C++ was installed - 2 restore points as of this morning. (I may be wrong).

I did the required up date a few days ago, and completely lost my Bookmarks....both on my toolbar and the "other Bookmarks"....

I have always used Firefox as my default, but now am at a loss, and am having to use Chrome. I have Windows 11 installed, so I am totally confused and shocked that this has happened to me.

Firefox updated and all bookmarks and history has disappeared. Is there a way to get them back?

Thanks, Scott

Running Windows 10 but with extra year of security updates. Several web sites were running very slow or not loading at all. So I tried doing system restore - only went back 3 days but afterward said it had some problems, and link to Firefox did not work. So I did system recovery back to time from which I had just done restore. But I had no link to Firefox so had to download it new. But now I have none of my previous tabs, links, saved passwords,,etc. I'm hoping my previous Firefox is still on my PC and there is a way I can run it.

I have been a Firefox user for many, many years. I started getting the Subject message: "The bookmarks and history system will not be functional" error message this evening. I started to "Fix" this error based on the Mozilla Support page. Actually, I first tried restarting my computer and that didn't correct the problem. I then noticed I could "sign off" Firefox which I thought I'd do and sign back in. I didn't notice until after the fact that my Firefox account was tied to a very old email address I once used that is no longer active "commish3@bellsouth.net". When I tried signing back into Firefox using that old email account, it said a security code would be sent to that old email address. Problem is I no longer have access to that email account.

1) Is there a way I can sign back in and have a security code sent to my current email address: tad3.dickinson@gmail.com ?

2) Can you assist with restoring my bookmarks. Again, years of building these bookmarks that I'm very dependent on.

Thanks, Tad Dickinson

I turned on my computer as usual , then the message about Firefox not being able to turn on because a file was engaged elsewhere (?) then without me pushing any keys my computer cut out and then restated after awhile. when it came back on I tried to follow instructions to restore my Bookmarks to no success. My next step was to change to another email address and received the 6 digget code which brought me to this current page. HELP Please.

HOW MANY TIMES can Firefox lose my bookmarks......again and again and again. Restoring from a profile is stupid because all new bookmarks are still gone. This product used to be good...now it is so unreliable that I am switching to Edge which never loses my bookmarks. NO.....I DID NOT DO THIS!! YES, YOUR PROGRAM DID AGAIN. NO I ADDED OR DELETED NOTHING. IT IS IN FACT YOU!! Every time an update in installed I face this. I no longer have a single shred of confidence in this product. Every month or so...BAM....bookmarks gone again. RIDICULOUS. And you want donations for this?
