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.

"how to revive return all 124 tabs of prior sessions ? in Firefox...older version ? please help. & How to avoid if close by mistake 1 window with all ....vs 1-2 tabs only ? " HOW revive replace lost all tabs 4 days ago ? '

I am currently running Firefox on Windows 11 (24 H2) and today, like I have usually done a lot over the past years I opened Firefox, did some browsing, then I quit the app. When I later opened Firefox (version 130.0.1 (64-bit)) no a single of my open windows got restored.

I have been relying on Previous session being restored. Today however, it did not work, and the option to use "hanburger menu" -> History -> Recently Closed Windows" do not show my windows I had open.

How can I find my old sessions? Can I restore them somehow from backed up data?

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. :-)

For example, say, you have 3 opened tabs in a Firefox (FF) windows. Normally, when you close FF and then re-open FF, it restores 3 previous opened tabs.

But, if you have another FF windows opened at the same time, when you close the FF windows with the 3 opened tabs and re-open back a new FF windows, FF won't restore the 3 opened tabs.

Same thing happens when you have another Private FF windows at the same time, when you close the non-Private FF with the 3 opened tabs, and then you re-open FF, it loses the 3 opened tabs.

That's why you can see 'countless' question about lost opened session, because of the issue above along with crash etc.

Is this a bug or a known feature?

I've never had this problem before, even though I've been using Firefox for 4 years. As soon as I try to connect to an account via Google, or go to Docs/Drive/Classroom, I'm always taken to a “Clear cache and delete cookies” page. So I followed the instructions on the page, deleted all my data and saved cookies from Firefox and even tried to reinstall Firefox completely, but nothing changed, I'm always redirected to this page.

Someone can help me please? I can provide more informations if needed.

Dear Firefox,

I have just reinstalled my operating system after some issues. After reinstalling my browser, I logged into my browser after changing the password, but now no data is being synced. The open tabs, bookmarks and saved passwords were the most important, but none of that has synced back. After waiting for a little bit I decided to press the synchronize now button, but that also didn't do anything. Is there perhaps something wrong with the syncing right now? Or is there another way to get that data back? I didn't save it as I normally don't have to.

Thank you for your reply!

Kind regards, Lili

When I sync my Firefox account, my old data, themes, and add-ons come back. There are add-ons, themes, passwords, and usernames from 3-4 years ago that I no longer use. How can I reset my sync data and sync again? In short, there is an 'overwrite' situation; the old data remains while the new data is synced over it.

The Firefox Sync system is really neat for keeping our booksmarks synced across devices, but what I would also love to see is the option to sync all settings as well, including the changes made in the "about:config" settings.

Across my years of browsing I changed quite a lot of small little things and having to track all of those down every time I set up a new device or reinstall windows can get a bit tedious, so I was wondering if those settings can also be included in the Sync settings somehow - or if such a feature might be planned for the future?

Dear sir

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.

Hello, I've got a bit of an issue with Sync. So, my current sync profile is outdated by ages, and I'd like to delete it completely and update it with all of the information on my desktop browser. But, when I try to enable sync on my desktop it overwrites my desktop profile with all of the outdated information saved on Sync. I can't seem to find anywhere to delete the saved Sync data so that I can upload a new copy.

I hope someone can help, thank you!

Hello,

I reinstalled Windows and Firefox at the same time, and as usual, I tried to sync my Firefox account. However, I can log in, but I get automatically logged out. I've tried several times, but I can't stay logged in to sync. Do you have any ideas? I'm using Windows 11 (10.0.26100) and Firefox 131.0.3 (64-bit).

Thank you very much!

Hello, FireFox community!

I use FireFox on desktop at home, at work and on mobile.

Recently I made an account at home.

When I log in to my account at work and sync which bookmarks (and settings) will last?

Which is the primary device?

Will my work bookmarks be replaced by these from home PC or will be supplemented?

I will appreciate your help!

Best wishes!

Hello,

Referring to your article [https://mzl.la/3TS8WcA] (Import settings and data into Thunderbird for Android) . The first step is : Export Thunderbird Desktop settings

   Click ≡ > Tools > Export for Mobile. 

However, I am running version 128.3.3esr (64 bits) "Nebula" and the menu "Export for Mobile" isn't available under "Tools" as mentioned in the article.

Please advise

I had a number of tabs open when my phone rang. After the call I checked the browser, and most of the tabs were gone. Usually there is an option to "restore previous session" in History, but it is not there now. I would like to go back to that previous session. Is there a way to do that?

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.

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.
