Firefox Community Forum

Stupid mistakes were made - I reinstallted windows and when I opened firefox I realized, that I did not know my password and also was not sure about the mailadress. I finally found an account with my mailadress but reset the password - it said that all data in the account will be deleted if I do that.

I got the old files recovered, but everytime I copy paste the old key4, login and cert file... nothing changes withing the browser. If I copy the whole old profile folder and exchange it with the new one and then I open firefox it just says "profile could not be found" and then firefox closes.

Is there any chance of recovering my old saved passwords or did I screw up entirely ?

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?

I have used firefox as my brouser on my PC for years with all my bookmarks and passwords. Now without my old computer, how do I restore all my account passwords and bookmarks as it was before.? I am using windows 11 on a Dell desktop PC. Please help. I am not a computer genius. Is there a phone number to call for live help.

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 ?

I suddenly got a message on my screen that my bookmarks and history were not available because another program and Firefox were trying to use the same application. I followed directions on how to determine the exact problem and cannot get anywhere with that. I then tried editing my profiles and ended up losing all but the main one, and there are very few bookmarks included with it. Would there be any way I can retrieve at least part of the files I have lost, especially my bookmarks? I thank anyone who can help me in advance.

My bookmarks are not working. Every time I try to click the star, nothing happens. I try to add bookmarks using ctrl d and nothing happens. This happened probably after an update from firefox (there is so many that I have to do constantly). I even tried restoring previous bookmarks, however it tells me unable to process the backup files. Ive even done "refresh firefox" "troubleshoot mode" and "clear startup cache" in the about:support area. Ive also reset my pc multiple times.

I would hate to have to use a different browser. PLEASE HELP FIX THIS

Dear Firefox Support Team,

My Mozilla Account was Accidentally Deleted Today and I'm Looking to Recover my Data (History / Passwords / etc.). Is There any Way to Do so?

Thanks in Advance

• Old laptop can no longer access the internet; corrupt Windows 10. Bought a new HP laptop. Have Sync turned on on both laptops but am not getting any favorites, passwords that I desperately need. What are my options given the old laptop can't connect.

I have lost all my 'Bookmarks' and have researched how to resolve, without any results. I still have Win10 but have signed up for another year or support. as you know, losing years of BM's is hard to replace. Any help would be 'GREATLY' appreciated. Thanks, Tony... [email removed]@yahoo.com

Hey guys, My friend got on my pc and shut it off without me looking and somehow when i opened it back up all my tabs(couple hundred) distributed between 3 windows were lost. I've tried all the usual recovery options by doing previous or session restore, its not popping up in recently closed windows as well, where i usually recover my sessions from if it does go wrong. Is there any other way where this data may be stored, to recover a session from 31st Dec 2025.

Would greatly appreciate any help :D

I am incredibly frustrated by the continuing problem of all my Bookmarks disappearing with the usual "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." This issue has been going on since NOVEMBER!!! I usually manage to get my Bookmarks back by closing all txt files that I need to keep open, store them in a new folder on my laptop, and then restart my laptop. This time, it didn't work.

Can anyone steer me to a permanent solution to this problem?

Thanks, in advance, for any help offered.

My SSD boot drive crashed -- Rebuilt system (brand new SSD boot drive) and reloaded all of my data from a separate backup, however Firefox profile is gone. I have copies of the old profiles including the places files, etc. Following Mozilla's instructions I reloaded the old profiles. Firefox starts right up but *without* my bookmarks, etc. Unfortunately there was no "old Firefox data" folder saved and I could not retrieve the bookmark specific backup. Thoughts? Thanks!

CCleaner wiped out my bookmarks and their functionality. I have repaired, then uninstalled CCleaner. I have refreshed, uninstalled then reinstalled Firefox. I have logged in and out of Firefox. I have made an HTML file of bookmarks from another device in order to try to import them. Firefox bookmarks will not proceed to an upload stage. I went into setting to add the HTML of bookmarks and it said "this is not a bookmarks file." Well, Firefox made that HTML bookmarks file so I have no idea how that could be. Nothing I have tried has worked.

Desktop Computer. Still on Windows 10.

Not sure of category. This began when I launched the computer today. I opened Firefox and got the message "The bookmarks and history system will not be functional because ....."

When I started to shut down the computer (first mentioned step here) I saw there's a Window update. I selected Update and Restart. That went okay, but still don't have my Firefox bookmarks.

So I clicked on Learn more. I found the Firefox > Profiles folder. There are two folders, one from today - qkuxm6ws.default-release - 15...... 0196 with 94 items, and 7ghfiw 15.default, from Jan 5, 2021, with 3 items. I assume I should use the one with today's date.

BUT .... from this point, the information on this website was full of information - NOT step-by-step information telling me what to do with which files in this folder.

Also, I have McAfee as well as Windows Defender. I opened Windows Defender Firewall. State is On. Notification state: Notify me when Windows Defender Firewall blocks a new app. I've gotten no such messages.

Under allowed apps and features:

 "Firefox ... private not checked; public checked.."  
 "Firefox (C:\Program Files\Mozilla Firefox" - private is checked, public not checked.  

Can't make changes.

Under Overview window: Not checked is "Inbound connections that do not match a rule are blocked."

• • • • In the "Monitoring\Firewall folder" - Firefox (with path) is listed twice. Both entries have Private, Allow, NO Override -
      • Differences - the first has UDP; the second has TCP. Nothing under "Group."

My last bookmarks backup was Jan 2025. 😕 😟

I don't know where else to look or what to do. Please help. Kami

cleaning up my computer, I accidentally deleted firefox. I had a list of favourite links, and I lost them. Is there any way of recovering my list of favourites?
