Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Firefox on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Firefox on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

Regards

Steve

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?

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

After a routine system restart due to display driver crash my Mozilla Firefox ceased to work, displaying a broken link. After some messing around I decided to reinstall the application, but when I did it was an entirely new instance with none of my local saved data (bookmarks, passwords, history etc). I've been able to restore my bookmarks, but not my passwords. I've found the relevant key4.db and logins.json files pertaining to the older intall, but I have no idea how (if possible) to install them, and I assume there would only be a compiled csv if I created it.

Help!

the firefox App has been unintentionally uninstalled when an additional widget has been drag and dropped to "uninstall" on the smartphone. Is there a possibility to restore previous session or the active tabs or is all this data also uninstalled/ lost? I have not been logged in with my firefox account.

Hi, I have a laptop i use for work and a PC at home, both use Firefox.

At home I am signed into a FF account, but on my work laptop i've never signed into FF before. I had lots of work-related bookmarks.

I recenlty signed into FF on my work laptop, in order to make sharing tabs to my home PC easier. Now all the local bookmarks I had in FF from before I signed in have been replaced with my bookmarks from my home PC.

How do I recover the bookmarks from before I signed in? Going forward, is there a way to organise different bookmarks on 2 different devices while signed into the same FF account?

Hi I have lost all my browsing history and nothing I browse is saved. Also all my bookmarks have disappeared and I can't save anything even clicking on the star doesn't do anything I have quite a bit of stuff bookmarked, can you help? The browsing history and my bookmarks seemed to disappear at the same time.

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 have lost all of my bookmarks, bookmark tool bar after Firefox's last update. I have spent the last day trying to recover what has been lost but I am having no luck in getting everything back in place. I have tirelessly gone over all your possible remedies and get no results. I can't even send a message to Mozilla through their help messaging system. My only recourse appears to start using another web browser. If I can't talk to someone who can help guide me through a mess I did not cause, then I am forced to find another company that is responsive to my problems. Call me at [edited] or write me at [edited] if you want to keep me as a user of your service. Regards Mark Hannah

I just upgraded from an older computer OS to Windows 11. I imported my bookmarks but really hate the new look of the bookmarks bar in Win11. The icons are all generic and have no color. I've attached a screen shot illustrating.

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.

Trying to sync/share open tabs on my old phone to my new phone. Tried selecting Share>Share all tabs>Google Pixel 9 Pro XL

Each time I've tried that, it says Unable to send

Hoping for some help.

Edit: A few hours later, and it magically works perfectly, feel free to close this. Annoyed at loss of data and it randomly fixing itself, but whatever. Sorry to anyone looking at this trying to find a solution as i did.

As in title, for context for a while I've been having minor issue with sync between these two devices, with the syncing being unreliable, often taking trying multiple times, closing and reopening mobile app, and opening a new tab to try and prompt a successful sync, as often the sync would "happen" but the tabs open on the mobile device would be outdated ones.

Today, sync failed to work at all, on both parts (Dekstop app, and android app), i couldn't see tabs from the other device on either device. Trying to resolve this issue, i relogged on both devices, set up and signed out of sync multiple times, disabled and enabled sync again, deleted mobile app cache and tried again, and even reinstalled mobile app and logged in again (which to my surprise, also wiped all my tabs, history, settings, which is quite an annoyance, but I'll leave as a loss). To note, both firefox PC and Android have autoupdate on, dekstop is up to date, though i think i noticed firefox app updating yesterday.

I have read through other firefox sync articles, but none of them provided a working solution. For information, i have noticed something that may be a hint or nothing , please see image attached (nr1). Another thing I've noticed is firefox view not showing it recognizes a connection, image attached (nr2). I am also providing an image of my connected services page, showing the desktop sign on and mobile sign in (whose last connected date does not update), image attached (nr3). Another curiosity is the refresh button in that page, when clicked, perpetually showing as "in progress", but not resolving or updating when i log in mobile app, to see that change only refreshing the page worked.

I really hope for some help with solving this issue. Firefox sync despite its unreliability has been a very convenient tool for me. Naturally if any extra info is needed, i am ready to provide it.

I can't find how to transfer existing files to sd card. My phones internal storage is almost gone. There is no space for even the smallest app. I have mounted and formatted the sd card and it does appear on my phone. I just can't access any sd card options. Thank you for help.

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

Regards
