Hello, Hi I recently updated (last night) and i didnt check all the boxes i clicked skip but NOW i can not recover any of the stuff from the night before is there a way u could help me ?!

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. :-)

Thanks to a Microsoft update my PC had to have Windows reinstalled causing me to lose all my apps. I have reinstalled Firefox on the PC but of course, all my bookmarks and passwords are missing. I had set up syncing between my PC and my Android mobile devices (phone and tablet). Can I restore or sync from the mobile device back to the PC? I have searched and found nothing. Even when signed into Firefox on the phone, it does not bring up "Sync" when I go to settings. I truly appreciate your help.

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.

Desktop FF version: v131.0 Mobile FF version (Android): v130.0.1

My profile seems to be corrupted. Starting Firefox with that profile completely crashes the computer, but when I reinstalled Firefox and it started with another profile it was fine. Switching back to my profile immediately crashed the computer. Is there a way to extract the history/bookmarks/passwords/etc. from my profile folder without starting Firefox? Thanks in advance!

This if Firefox 131.0 on MacOS 10.15.7 (Catalina).

We deploy Firefox via a software called Pulseway and last night it reinstalled Firefox over the current installation for one of our users. When he logged in this morning, all his data was missing from the browser as it appears to be a fresh installation. I'm unable to find his previous profile in the AppData folders (checked by going to about:profiles and opened each profile). There is no backup for this info, and he did not have a Sync account set up. Is there anywhere else I could possible recover this data for the user? Thanks in advance.

Hello,

I have Firefox browser and ATT internet and email. I was unable to load email today until I spoke with live ATT tech support. He instructed me in clearing cache and cookies, had me open a private window, then asked me to open another window. He did get my ATT email restored, but when I had 2 windows open I accidentally closed my main window which had many pinned tabs and other tabs I wished to get to. Yes, too many tabs! So I have a new browser which does not have the configuration I want which is the one I had when I first called ATT. So I made a mistake and closed the wrong browser, I knew it as it happened but it was too late, I guess speaking with and listening to the tech messed up my concentration. I have made this mistake before and closed the wrong browser but fumbling around somehow I managed to recover the browser I wanted, I don't remember how exactly. I think it has been a couple of years since I screwed up this way. The History section of my Firefox menu does not offer a selection called 'restore previous session' that the instruction page shows, the only options at the top are Recently closed tabs, Recently closed windows, Search history. Then a bar followed by Clear Recent history, then today's history in the new browser. So I only get history from today's new browser. I am old and not tech savvy there is a lot of terminology I do not understand, I need a kindergartner's step by step instruction on this I am afraid, in clear English. I am afraid to do things like refresh or reinstall without knowing what I am doing. I appreciate your help. I use desktop Firefox for email, reading items of interest, social media, ordering merch. I do not do gaming, I have no website. It is late and I am going to bed soon. You can email me at jaelizlang@att.net. Thanks so much, Jane Langston, Clarkston GA

How could i restore the bookmarks that i mistakenly deleted? Going back to the sync from 2 weeks ago, I don't have any of my bookmarks at all, I don't have them locally saved, the deletion happened before I reinstalled the operating system

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

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'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

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 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?

I am going round in circles. The last Firefox update reset my Firefox on my laptop to default settings including losing my master password. I started to reset all my old settings but when I got to the part where I setup the sync with my phone version of Firefox, Mozilla asked me to log in. My password was not recognised so I hit "Forgot password" having set up a new password using one of my 10 digit authentication codes, I was then asked to log in with my new password, I did this & when trying to do the sync, I am being asked for a six digit authentication code! I have no idea where to find this code. Please help.

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!

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 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.

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 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.
