Hello,

I accidentally disliked a thought-provoking story which involved the couple who died in the Lisbon funicular crash (as of Saturday 6th September 2025), which I think was addressed by The Independent.

Is it possible to reverse the dislike? The story does not seem to appear again, at least from what I have seen. Although the dislike was accidental, I felt that having the story disliked would indicate I would not be interested in thought-provoking stories about those who have died, even though these stories should be important to show.

Today I installed a clean WIN10 version on my PC, expecting to just log into firefox afterwards and have all the data back within minutes, but I forgot my Firefox password... As I'm currently in another country I also couldn't just log in on any of my other devices to recover the password, so I decided to reset it via the E-Mail... well aparantly changing your password deletes the sync data?? I'm guessing there is no way to recover the data? So I got a relative of mine to start my backup notebook which has not been synched for a few months but some data should've still been there, at least I had thought so... password database there was empty... and instead of synching the firefox landing page from my notebook where all my pinned pages were, it copied the page from the new device and wiped that as well... Any way to revert the sync changes on the notebook?

I am using duck duck go. I was backing up stored settings and accidentally re-installed google. I cannot get duck back in mozilla settings--It says duck is my default, but moz opens to google. oops and help Thank you, Elsie [edited email]

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!

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.

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!

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,

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

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.

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 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

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

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'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.

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.

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.

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!
