Firefox Community Forum

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.

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

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.

Today randomly i noticed that my bookmark bar is waaay shorter out of the blue, i didn't change or adjust anything, all i do is the updates from mozilla that's all, it was all music it really saddens me because atm it's lost forever, i hope somebody can help me (i don't know since when it disappered i literally just noticed it right now ...)

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

There was an update today on my PC laptop, I think from FireFox. After the restart, my bookmarks have all disappeared. The instructions to restore them are useless. I go through Menu/Bookmarks/Manage Bookmarks/Import and Backup/Restore/Choose File. THERE ARE NO FILES TO CHOOSE FROM. According to the instructions, there should be some dated entries. Nada.

I tried the Troubleshooting blahblah and that was equally useless.

I'm panicking that I've lost years of carefully organized bookmarks.

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. :-)

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.

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.

Transferring bookmarks & backups for passwords is easy and I'm not worried about that. But the about:config settings that I have customized and accreted over years so that nothing beeps, spins, auto-plays, loops, or throbs a tab, are not so straightforward. I'd like to review what files I can save how to make sure I do not lose these, which are the most important things to me about my Firefox installs--keeping the web safe for quiet, nondistracting searches and reading.

Windows 10 Enterprise, managed by my organization, but with just enough admin privileges to customize my Firefox.

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, 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?

This will be a long question and in 2 parts, so I'll apologize up front.

1. I am running FireFox on my 11-year old MacBook and love it (MacOS Mojave version 10.14.6). However, my printer just crapped out, and my new HP 9120e requires MacOS Big Sur (11.x.x) or later. If I update to that OS, will I still be able to use FireFox? If so, where do I find it (see Question 2, below)?

2. Since my old MacBook is clearly reaching the end of it's life and my Excel and Word apps are also ancient, I am trying to transfer all my stuff onto a "New" MacBook that is running MacOS Monterey version 12.0.1. However, the "New" computer (I will not say "improved") has been a reliability nightmare and I just had it in for service. They wiped my disk clean to install the Monterey OS. So, other than Safari, I have no browser (or anything else for that matter). When I go to the App Store to download FireFox, and don't see it anywhere. Help!

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).

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.
