Firefox Community Forum

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?

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!

Sam

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?

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?

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.

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

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 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 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. :-)

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 could not remember my pw today when trying to get bookmarks back on this computer, so reset, thinking I would otherwise be locked out --now I'm not seeing an option to sync bookmarks. I'd love to get back these bookmarks--a treasure trove of resources gathered over 9 years. Any help greatly appreciated!

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking
