On 10/5/2024 I suddenly had no access to my saved passwords for websites, all my bookmarks were gone and no autofill works anymore. I have searched and searched for anything relating to these missing saves in password manager, I've used EaseUS, I've tried system restore. It's like my my saves were completely wiped! When I did a system restore, Firefox uninstalled itself completely when it shouldn't have. Now it's like I never had Firefox on this pc and there's no history or anything dated before today 10/6/2024. I've tried import from other browsers and there's nothing there. I'm a bit upset here, is my history, saved passwords, bookmarks and, autofill just gone and irretrievable?

I use Firefox on Ubuntu Linux, and it works fine.

For unrelated reasons I have created a new Linux Mint 22 boot partition, and I would like to use the same Firefox profile on both Linux OS-s, without having to move or copy the existing profile I use on Ubuntu. (The profile is placed on a third independent data partition!) I cannot find any information on how to do it. All information I find involves moving the profile, but then Firefox on Ubuntu would not be able to continue to use it.

I look forward to hear from you. Thank you. :-)

Yesterday, something went wrong in my Windows 11 desktop (I have a virus program installed). One of the casualties involved corrupting Firefox (it would not open). I reinstalled Firefox without removing the old version. Now I have a new installation but all my bookmarks and other data are missing. There is a folder on my desktop labelled as "Old Firefox data". It is possible to restore Firefox to a previous time (a day ago)? Thank you.

I’ve been using Firefox on my Mac without any issues, but I recently had to erase and reset my Mac. After reinstalling Firefox and attempting to sign in to my account, I am unable to sync my data.

When I click “Sign in” and enter my password, I successfully log in. However, it immediately returns to the message “Please sign in to reconnect,” and I am unable to proceed with syncing.

This is the first time I’ve encountered this issue.

On a positive note, I can still see my organized bookmarks on Firefox for iPhone, which were synced from my Mac before the reset.

I often use the Sync function to bring open tabs over from my smartphone to my desktop computer. I have noticed over the past month or so, this functionality has become increasingly unreliable and sometimes does not function at all. At the moment I have no synced tabs showing on my desktop. I have signed out and back in to Mozilla on both my smartphone and desktop multiple times, checked the sync settings, and nothing seems to resolve this. There have been a couple Firefox updates on both the desktop and mobile side, none of which have changed this behavior.

Has anyone else been experiencing this? What other trouble shooting steps can I perform? Any help is much appreciated.

I opened firefox profile manager using 'firefox -p' and tried to delete one profile...firefox deleted all profiles except 'default' and 'default-release'...even with them firefox renamed them with some number suffix and created new folders with the same name ('default' and 'default-release')...I have checked /home/ubuntu18/.mozilla/firefox folder...all profiles/folders gone...UPDATE: As I was typing this there was power loss, firefox deleted old 'default' and 'default-release' too...How to get all profiles back?

Hi,

My laptop had broken and I had to reinstall Windows. All of my files had been lost on the C drive, including Firefox bookmarks. Sadly there weren't any backup json files anywhere else. Is there a way to recover those bookmarks somehow?

Thank you, János

I'm taking nightly incremental backups of /home for example to my home storage server and, I guess, due to the databases Firefox uses for various storage, those can't be backed up by just copying them, if Firefox is running and has the database open.

What are the best practices, then, for ensuring all profile data, including these databases, is in a state where it can be backed up, while Firefox is running, in a way it can be restored to a fully functioning profile?

For example, with MySQL databases, you can dump the log before running the backup each night, which basically exports the SQL statements needed so you can skip backing up the actual binary database file (like ibdata1).  Does SQLite need something similar?  and is this the only special consideration that is needed, or are there other specialized types of data within our profile directories that can't be backed up by simply copying the data while Firefox is running?

Thanks

All of my desktop bookmarks are on mobile, but after resetting my password they won't sync back to my desktop. I can't even access them from my desktop, despite browsing data still being clearly accessible. I have 10 years of bookmarks on my mobile device that for whatever reason now will not transfer to my desktop firefox no matter what I try. Since there's no way to manually export to xml on mobile I have no way of accessing these and I am at risk of losing 10 years of bookmarks, many of which are vital to the work I do.

I am trying to get rid of old bookmarks.

I logged out of all my devices except my main PC, deleted many folders of unwanted bookmarks.

changed my password

on my other devices that were not connected to sync, I deleted all bookmarks completely.

I only wanted what was on my main PC that I worked so hard on.

now tonight on my PC all the old bookmarks are back again.

this page doesn't make any sense, there is no option to "Delete data from this device" when I sign out.

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

Firefox Extension "Tab Session Manager" will not open saved session tabs as a GROUP

From session to session, Tab Session Manager (TSM) displays any tab I have left open when I shut down Firefox. The TSM display of tabs appears in a vertical column (left side of screen) provided by the Firefox extension, Tree Style Tabs. At any time, I have a total of perhaps 600 tabs distributed among four separate windows in TSM, with each window linked to the task bar at screen bottom, letting me choose which window to display, full-screen,

Running Windows 7 64bit SP1, I have had no problems until now displaying any of the four windows, one at a time, in the left column of my screen. Yet, now, I lost one of the windows when starting a Firefox session, and only three windows appear. Trying to recover all of the windows, since I have no menu option other than to restore the entire four window backup, I have clicked on TSM's top menu to restore all four windows. TSM does respond to my single, left-click, but restores only one window of the original four. A right-click of the TSM menu at top right of my screen makes no reference to "restore all windows in selected backup" or "restore all windows in latest saved session".

Essentially, TSM has maintained a perfect record of all TSM backups ever made, each showing date and time, but since TSM now will not restore all windows, my operations in Firefox are crippled. In past incidents when windows have been missing, I have successfully restored all windows of any backup (each backup a set of multiple windows) chosen.

My "brute force" recourse is to restore the entire Windows 7 volume from a very recent image made in the imaging application Macrium Reflect, since all the TSM windows are so valuable to my work. But that does not resolve the TSM failure to restore all of the saved tab collections.

Meantime, I have located the repository of TSM image collections, and have been able to make test backups of large numbers of tabs, and restore them properly and completely. The major problem that remains is restoring all of the tabs from multiple windows contained in the same backup, as I could before. I have tried to reach a TSM community discussion on a GitHub link, but am uncertain where to proceed next.

Somehow I lost all my Firefox bookmarks and passwords when computer was rebooted with a Windows 10 restore point. I am having difficulty installing an old firefox profile into the new Firefox browser. The Firefox Trouble Shooting suggestions are very confusing and hard to follow with lack of step by step detail. Help!

I do a lot of research, and may have 300 - 400 tabs open. 2. I needed to do a clean install of Win 11, so I saved my open tabs as bookmark, I checked and they were all there. I also saved the folder from AppData Roaming - Firefox\Firefox\Profiles\ivdajzll.default-release\sessionstore-backups. Only when I open a tab with about:sessionrestore, the below Restore Session button is grayed out.

I then exported my book marks as an HTML file. I installed FF, opened up bookmarks manager, and chose to import from html, pointed to my saved file and selected open, nothing happens. When I look at the side panel in bookmarks manager, my book marks have not been added.

2. I also tried the second option by opening Settings / General / Import Data and Select the Bookmarks from HTML file option. I point to my saved html file, it spins for a few seconds, says success and I click on the Done button, still my bookmarks have not been added.

I've just transferred from one Windows 10 install to another, and wanted to transfer my Firefox profiles along with me. Initially when I transferred over my main profile, the addons worked at first but broke after a short while (specifically there were still as many addon buttons in my toolbar as before, but they were all blank and did nothing), and wouldn't restore after shutting down and reopening Firefox. At first I tried disabling and reenabling each extension, and that worked, but after shutting down and reopning Firefox, they were all broken again. I looked for fixes and tried the solutions in this ask: https://support.mozilla.org/en-US/questions/1260445; first, I tried jscher2000's solution of "deleting" extensions.json by renaming it, but it only fixed a couple addons (BitWarden and uBlock Origin, mainly). Then I tried cor-el's solution of deleting combatibility.ini, and that still only had BitWarden, uBlock Origin, and maybe one or two others working - it also seemed to slightly further the problem, as the toolbar was now set to default without even the blank addon buttons, and the extensions overflow button now just opened about:addons.

But, then I deleted the profile and copied it over again, but this time I preemptively went into extensions.json and changed all the paths to the new correct path (I also did so for the one path address in pkcs11.txt just in case, because it was the only other thing that came up in a search in the profile folder that had that hard-baked full path that might need updating; I don't know what pkcs11.txt does but I just wanted to be sure), and then (not sure if this part matters quite as much) did Create a New Profile and selected that existing copied-over folder as the folder for that profile to use. Lo and behold, all my addons worked! And they've continued to work as normal and not break through several times of closing and reopening both that specific profile and Firefox overall, and even with a couple shut downs and restarts of Windows.

However..... I tried doing that exact procedure (copying over profile folder, editing the paths in extensions.json and pkcs11.txt to be the new correct ones, Create a New Profile and selecting that folder) for my secondary profile, and yet still most addons end up nonfunctional with a defaulted toolbar and extension overflow button opening about:addons just like in the main profile after I did the compatibility.ini fix (even though I didn't even touch it on this profile). After several tries of doing that with differences in naming of the new profile, or also trying to delete compatibility.ini, still I got the same result. Then I tried doing the "disable and then reenable each extension" thing again like I tried first on my primary profile, and it brought the extensions back and in their correct order in the toolbar, but when I exited Firefox and reopened it, they were back to the multitude of blank buttons (which, at least, was a change from before). I have no idea what's different, as far as I'm aware I'm doing the exact same thing that worked on the first profile yet it's still ending up broken.

I've also now tried copying over a third profile in the same manner, and it works perfectly just like the first/primary profile did. But the second profile still just will not work.
