I-Firefox Community Forum

So Firefox was failing me as it wouldn't play YouTube videos, so I tried rolling it back, which failed. So I reinstalled it and it's not saved any of my data, despite making an Old FF data folder. When I sign in with my account, nothing. I have it installed on my phone and when I try to sync it, it asks me to click on synchronise and save data, which isn't even on the menu!!!!!! How could you get such a basic thing wrong? Is that it now? I have to start right from the beginning and gradually go through every password and bookmark???

Please tell me there's a solution because this is really annoying.

Hi! So I have both a (admittedly pretty old) laptop and a desktop, and thus every so often manually move my backups to and fro. I have cookies and cache that I cannot afford to lose because there'd be no 'backup' for them, it isn't stored anywhere else, so if it's gone, it's gone. Just today I was doing the same old, going to /Roaming and /Local, zipping them, moving them over on a usb. But today I see that alot of my roaming files have a '.corrupt' and is listed as a 'corrupted file'. My firefox is still working, I'm even using it right now, but I'm nervous that could change and I might lose access to the cookies and cache. It'd also suck to lose my passwords and bookmarks as well. Any advice so that I don't get a nasty surprise later?

I just downloaded Firefox for Mac OS on my Macbook Air. Doesn't look like the bookmarks, their folders, the most recent passwords have synced from the Mobile version of the software to the desktop here on my Mac.

Hi,

I have had to reset windows, after reset I also upgraded to Windows 11. I have to reinstall all programs including Firefox but understood all my data would be available and most of it is. I have reinstalled Firefox but did not have immediate access to my old Bookmarks and Passwords etc. I have found the Windows.old file but that only contains Microsoft files, nothing from Mozilla. I use File History as a backup but only for my personal data files.Can anyone tell me if there is a way to get the Firefox Profiles back please?

How do I export my address book (and not my whole profile). I used to be able to send it to a CSV or LDIF file but those options appear to have all disappeared. I do not want to export my profile - it is way too big.

I am running TB 128.10.2esr (64-bit) under win 10 on a Dell laptop. Thanks

Logged out all my personal accounts from my computer while I had it serviced but I couldn't get my bookmarks and passwords back after logging out in Firefox. Tried some troubleshooting steps including logging out from all device but now even my phone, which previously had the bookmarks and passwords saved, are missing it

When I opened Firefox today, ALL of my bookmarks were gone. There was a message saying that they couldn't be accessed, and that sometimes securiity software incompatibility is the culprit. I'm also now unable to create any new bookmarks. I have no idea what may have updated, and don't know whether to blame you, Windows/MS, Xfinity, or the McAfee prompt which keeps trying to get me to finish installing something I never intended to install in the first place, but can't get rid of. How do I get browser bookmarks back?????

Is there any program to recover the profile? Using Firefox and LibreWolf, I find that when I reinstall the program, the saved profile from a previous version isn't recognized by Firefox or LibreWolf. There's no way to recover the entire profile without problems; it can only be achieved by copying a few files from the old profile to the new one.

For a long time, it has been impossible for both browsers to transfer/copy a previous profile to the new installation, for example, from version 137 to version 139.

Desde hace mucho en ambos navegadores es imposible trasladar/copiar un perfil anterior a la nueva instalación, por ejemplo de la versión 137 a la versión 139

I had to quit Firefox this morning because of a problem with my proxy and when it reopened it had updated to Firefox 139. In the process, I lost my entire browsing history and all open tabs from my previous session. Although in settings I have "Open previous windows and tabs" selected always, when Firefox restarted the browsing history was empty and "Restore previous session" was not an option under history, nor were "Recently closed tabs" or "Recently closed windows." I cannot locate any backup files in the Firefox library on my computer (MacBook Air running Ventura 13.7.5). I really need to be able to restore the previous session, please let me know if this is possible.

Sometimes, when I first boot up & open Firefox, I am given the option of problem fixing, but extension button are removed. What is the benefit of this process?

I always start my Firefox and restore from last opened state. I have used tab groups for a while and had a few of them saved&closed while I used some just a few days ago. Now all my groups are gone. Which is kind of annoying, since I used one Tab Group for my thesis and it had about 150 tabs or so with references and sources that I used.

Is there any way to restore tab groups? Are they stored externally somewhere in the instal directory?

Thanks in advance.

After entering my windows log in many, many times in "Export logins" Firefox says wrong password. I am logged into outlook and microsoft account settings as well...how can this be the wrong password???
