my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

I needed to have Windows 10 wiped and reinstalled from my laptop, and the guy who did it cloned my files to save everything. I saw instructions on another post on how to find the bookmarks file under Profile, but it didn't do anything after confirming that it would wipe out all current bookmarks. What am I doing wrong?

I store passwords on firefox account and use sync to share passwords across devices. I did not delete any passwords on any device. recently, I saw that only google account passwords are missing and rest passwords are intact in saved passwords. my google passwords have been stored since a long time. all my old and recent stored passwords are shown in firefox but only my google account passwords are gone on all the devices. I tried login-backup.json but there is no change in passwords shown. need help.

Firefox was one of the system updates I installed today on my Linux Mint 19.3. I updated it and discovered all history and bookmarks are gone. I have no Old Firefox Data folder. I tried about:profiles but the only other profile is the default Linux one. I tried to Restore from Import and Backup in Manage Bookmarks for several different dates, but only get "Unable to process the backup file" error. I also tried to choose several .json files from the STG-backups-FF-8x folders in Linux Downloads directory, but it doesn't seem to do anything. I've tried using Timeshift to restore from previous system dates, but it would only create Firefox folders with the same outcomes as above. I don't really care about history, but I have a lot of bookmarks that would be very difficult to recreate.

Thanks, in advance, for any help getting my bookmarks back!

I recently got all new devices and traded in my previous ones and when trying to login to Firefox Sync, I can sign in successfully but then I’m required to provide the 6-digit code that is sent to my email. I am unable to login to my email because the password in stored in my Firefox Sync saved passwords.

Attempted to reset my email password (Gmail) but I need to enter the last password that I used, which I have no idea since I’ve always used Firefox Sync and all I get from Google is “we are unable to verify this account belongs to you”. So not much traction on gaining access to my email account.

In my mind, I assumed that by utilizing Firefox Sync as a form of a password manager, I wouldn’t be in this situation as long as I knew my Firefox Sync password. I have since learned otherwise. I can sign-in on accounts.firefox.com but of course making any change requires that I put in the code that was sent via email.

I attempted to download Lockwise and again prompted to enter the code sent via email.

So at this point, I’m just wondering if I’m out of luck and although I know my password to my Firefox account that I’ll be unable to regain access to it or my email because I can’t access the 6-digit code being sent to that email.

Any additional support or suggestions are appreciated but I feel like I’m unfortunately at the end of the line here on what else could be done.

This new 'update' has just caused me to lose all my tabs and bookmarks. The new version is c**p and it is awful. I went to the page to install the previous version I liked and worked perfectly and when I installed I now have none of my tabs and bookmarks. My pc is nearly unusable and I am now out of business until I can get them back if I can. It will be months to try to get back to where I was and will never get all of what I had. Is there any way to fix this? I need help immediately.

I've had a smooth ride with firefox sync for a few years now and I have admired how quick and safe it has been. I was a long time xmarks user. However today it went off the rails. I booted a virtual machine for the first time in years and while on that vm I used firefox. That copy of firefox had never had sync enabled and the bookmarks were very old. I uncautiously turned sync on, thinking that it'd favor the current bookmarks over years old bookmarks. Nope. Now I find all of my active instances of firefox (all windows flavors) have bookmarks from 2016. Two things.

1. 1 What's the best way to restore my current bookmarks? I have backups from last night and maybe even more recent. I know how to restore bookmarks...but I'm concerned that sync will just repeat the same error and adjust to the 2016 set.
2. 2 How did this happen? I have gotten to trust sync so much that I just enabled on the old firefox without taking any precautions. That was probably a mistake plain and simple - sync is complex and that sort of gap in dates could be unanticipated. But still it seems odd that sync would favor an ancient set over the current set.

Firefox is a great browser and sync is part of that greatness. Thank you mozilla.

I installed the last update, my bookmarks kept being here but all my add-on, website shortcuts and firefox settings got removed. I checked the profiles to see if it was just another profile that was created but after checking each profile that was available they were all with the defaults settings without shortcuts and without add-on. I cannot recall all the add-on and websites saved so it is very important for me to recover them. What can I do?

last night was a firefox update??? today, all of my bookmarks and toolbar is gone. i've followed the RESTORE option and get an error stating that the function cannot process the backup file. WTF Firefox ... I have over 1300 bookmarks and use most of them regularly. help me fix this!!! ::crying::

Hello! Since the most recent firefox update, my settings and extensions have been inaccessible to me due to my firefox account profile being "old." It has been working perfectly until this update, where if I try to change my profile to my old one, it forces me to create a new one which does not include my saved addons, settings, or bookmarks sometimes. I really need access to some of these things, so it would be great if someone can help me to recover it. I tried to troubleshoot by finding my extensions local folder from my old profile, and I copied it to a new profile, but it didn't work. I am also wondering, if I do copy the extensions successfully, how can I also copy the settings preferences? Any solution is appreciated, thank you!

I have three devices, a desk top, a laptop and an iPad. The desktop is running a very outdated version of Firefox which means it is not compatable just to update it. The forum tried to help me with this a while back, but it was deemed not to be possible, and the best way would have been to do a fresh new install, but there was noway to save log-ins/passwords bookmarks. My devices all have the Firefox sync and that is so far working well. My question is, if I dragged my PC's Firefox into the present by performing a fresh new install, would my synced items install ok....after invoking the Sync feature on the new install. Logic tells me this should be so, as it worked ok with the new iPad, but I know from experience that logic doesn't always come into play. (Windows7) Many thanks

I decided to clean up my password file and get rid of hundreds of logins that were no longer active.

I exported the passwords to logins.csv and Removed all passwords from Lockwise. Then I imported the CSV file into a spreadsheet and edited the file, and exported a new copy of logins.csv.

Since FF Lockwise would not allow import from csv files, I imported the csv file into Chrome, then I opened FF and Imported passwords from Chrome. This was successful, with a total of 592 passwords imported.

But every time I close FF the next time I open it, all passwords are gone. The logins.json file and the logins-backup.json file are in the profiles folder C:\Users\Jerry\AppData\Roaming\Mozilla\Firefox\Profiles\04bmixuw.default.

I turned off SYNC but this didn't help; I turned SYNC back ON but it didn't help either.

This is now driving me crazy. Can anyone explain how to stop this insanity?

FYI I tried to upload images but the Upload Image feature never worked. Little circle kept spinning.

I am on Mac OS 10.13.6 and I cannot open Firefox and it says Profile Missing, and will not open. I don't care about any bookmarks or anything I just want to use Firefox as an alternative browser to Safari.

My PC (running Windows 10) crashed and when I restarted I'd lost all of my bookmarks plus I was prompted to create a new user profile. I'm running Firefox 89.0.1 I've tried following the information to find and restore my bookmarks but when I try this all Firefox prompts me is to import from another browser platform (which I don't use). Any ideas?

Hello to all,

I'm a "beginner" on Mozilla sorry if my question seems stupid, moreover, English is not my mother tongue. Mozilla is my main browser since 12 years.

I had a 2011 mac (personal) on which I had a bunch of bookmarks and passwords saved since 2011. I had Sync enabled back then and have a Firefox Sync key (8 series of 4 numbers/letters). On another Mac (for work), much more recent, I also use Mozilla and I created an account (with my email address, the same one I probably used in 2011) as soon as I installed Mozilla.

I have the impression that in the meantime the way "Sync" works has changed (before with a key, now with a login/password).

My problem is the following : my personal Mac broke (impossible to turn it back on) and I would like to be able to recover my bookmarks by posting them on the new Mac (pro), but... I can't find anywhere where I could enter my Firefox Sync key. I can "log out of my account" or "connect another device" but nothing else. When I log out of my account, I can log back in but only an account with an email (the only thing it asks me is an email).

Would you have an idea how I can get my bookmarks back? I had a hundred of them, very well organized, for professional purposes and I really need them. How can I keep my account (with my email) and add my bookmarks saved on my Key Sync ? (if needed, I can migrate all my actual account (profesional) on Google Chrome and start again on Firefox with my Key Sync but, I can't find how..)

Thank you very much for your help and advice

The last Firefox updates have suddenly created havoc. None, absolutely none of the websites that I frequently visit will have my login information saved even though when I view logins in the settings mode, they are all listed there with the correct passwords. I am not technical and would sincerely appreciate a tutorial of some kind as to how to correct this egregious oversite on behalf of the Mozilla team.
