I had experienced the dreaded "XPCom error" and had to do a clean reinstall of Firefox (I know, I should've followed the rule of saving anything important in 3 separate locations.) I had re-logged in and noticed I didn't have any of my bookmarks or anything. Am I out of completely out of luck in this case of trying to get anything back?

After installing Mozilla on my mobile phone and syncing with my laptop all my bookmarks and history are GONE from my laptop. When attempting to restore them, following your suggested instructions, no dates appear when clicking the restore function. Deleted Mozilla from my mobile phone, still no good. Do I need to recreate all my bookmarks again?! How? When attempting to bookmark a new site it does NOT bookmark! No new history is showing either! Very disappointing, should I just return to windows again after years and years with Mozilla? Andrew S

I had sync turned on before I reinstalled my OS, and now I have lost everything. Is there anyway to recover the stuff that should be there? Yes or no. If yes please provide steps, and not the self help articles here as they are worthless.

The Firefox for Android application data grew excessively, exceeding 1GB. Clearing the cache did not help, nor did deleting site data from within the app (while keeping cookies). I was forced to use the "Clear data" option from the Android system settings. This completely wiped all settings and extensions. Despite having Sync enabled, logging back in did not restore all extensions, settings, open tabs, shortcuts, or organized saved sites.

Firefox has exceeded all previous mess-ups by upgrading itself today (apparently sometime when my battery went flat and was then left recharging), and this happened despite my account being set for 'upgrades to be only installed manually'. Now every bookmark, all passwords and all the settings of my Home Page have been erased. I have no 'restore point' to resort to as supposedly all this info is synced to the cloud. But I can find no method to retrieve any of these files let alone one to restore them. This is a nightmare. Please help.

Firefox keeps stopping on my Android; in fact, it won't even load. I have tried clearing the cache and clearing the storage, but that has not solved the problem. If I uninstall and reinstall Firefox, is there a way I can save my bookmarks? I don't think I am currently signed into (or registered for) Firefox Sync. I am hoping it might be possible to do that from my laptop. The bottom line is I really don't want to lose my bookmarks if at all possible. Thank you for any help/ guidance

for context: my laptop was working/running completely fine last night, as of about midnight (east coast). booted it up around noon today to see that it was super slow and kinda laggy (this is a windows problem, not a firefox one, don't try and fix that, i know it sucks), and that if i restarted/shut down, it would automatically update (not what i wanted). when i did finally begrudgingly restart my laptop, it auto-updated as windows does, and i expected to open up firefox and go on with my day.

unfortunately, it prompted me to make a new user. and when i signed into my firefox account, it treated the browser that i have used for at least 8 months like i had freshly downloaded it. all of my history on here is gone. all of my bookmarks are gone. when i connected my phone to try and sync from what i had left before i updated, all my sync information went down the drain and is completely gone as well. i really don't understand what went wrong here, and i'm honestly devastated that all of my work and my history has to be painstakingly rebuilt.

if anyone has any idea of what happened here, it'd make me feel a little better and try to avoid it in the future.

My language changed and I couldn't figure out a thing

So like an idiot I decided to reinstall hoping it would auto sync back

Now all my info is gone help plz.

Hello,

My personal toolbar and all my bookmarks were saved to my account at [email removed]@u-bordeaux.fr, and today at 11 a.m. I lost everything. I can't seem to recover these bookmarks; I think there was a synchronization issue. Can you help me recover what was lost? Best regards, Jonathan

Dear Firefox Support Team, I am reaching out for assistance with recovering my bookmarks, which are very important to me. Recently, my laptop broke down, so I created a backup of my files and system. After purchasing a new laptop, I installed Firefox and attempted to restore my data, particularly my bookmarks and passwords. Unfortunately, during the process, I had to reset my Firefox account password because I had forgotten the original one. At the time, I did not fully realize that this would result in the loss of my synced data. I later learned that this action may have removed access to my previous settings. I checked my backup files, including the Application Support folder, but I was unable to find the necessary data to restore my bookmarks. I am certain that synchronization was enabled on my previous device, but after logging into my account on the new laptop, none of my bookmarks were restored. This situation is quite urgent for me, and I would greatly appreciate any help you can provide. Is there any possibility that my bookmarks could still be recovered? For example, do you have any server-side backups or other recovery options available? Thank you very much for your time and assistance. I look forward to your response. Stepan

Firefox keeps just not work after I restart my Mac on the latest OS.

Now I have reloaded firefox and all of my bookmarks are missing and the account is unscynced?

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

I switched from Windows to Linux. I have signed in and tried retrieving bookmarks, browsing history and passwords, AFTER already having formatted my computer and deleted Windows. I signed in to the same account, had syncing on, but i can't seem to get any of the stuff back. I didn't have any additional backup files with those. Is there anyway i could somehow restore it all? The bookmarks are most important to me out of those. I'd be extremely grateful for any help

My computer crashed and after restarting I have lost my account data including profiles, history, bookmarks, extensions, open tabs, etc.

I have tried the basic methods suggested online like looking for hidden profiles, finding a folder for old Firefox data on the desktop, restoring from apparent backups that are meant to be there, etc. The account should have been logged in all this time and had sync on, which is not working... but should there be some sort of sync history I can restore from? Or a local backup from somewhat recently?

Thank you

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

You jerks deleted passwords and bookmarks I needed for work just because I reset my password to login. Why in gods name would you think that's a good idea? Why would I ever use your sync function if you're gonna delete my data the moment you get the chance?

My firefox recently crashed (f5ea38ba-f4f8-4224-8ab8-982e19cc72f7) is the crash code if that helps it happened just now, i dont have any additional profiles and no folder such as "old firefox" is there any way i can recover all the information and my old settings or passwords or anything? I tried to log into my firefox account to sync up data but there was no update on the information

Hello,

I am contacting you because I have a colleague who lost all her bookmarks when migrating her Mac computer. She was syncing with her Professional account. When she migrated and used her account to recover her bookmarks, no data came back. Her laptop was wiped and then reinstalled, so it is not possible to recover any data from it.

Would it be possible for you to find his bookmarks?

Thank you for your help.

Best regards,

Frederic Migaud

My pc just did the latest update, the one with the new Logo. It wiped out all my bookmarks and passwords. I can reset the passwords, but I have hundreds of hours of research which was all bookmarked. I have changed laptops four times and each time I did, I would just sign into my Mozilla account and it was all downloaded into my new one.

Did anyone else experience this and were you successful in retrieving this data? Do you have any tips? This was important information on a health condition and I don't know if I can find all of this again.

Please, please help. I tried doing what I found in your forums but nothing helped. Could it be that the information was wiped out by your servers and it's permanently gone? I really need help. Thank you.
