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 recently updated Firefox on my computer. After that, I can't find my old Bookmarks.

Also I find that I am UNABLE to add any new Bookmark. When I click on the 'Star' in the browser toolbar, there is nothing. Before I used to Get the Add Bookmark tab and a place to SAVE, now there is nothing.

Even after I type in the URL in the address bar, and open up the required page, I am unable to Add it to my Bookmarks.

Please Help!

A while ago, my browser refused to start. Apparently it got corrupted during an update and i had to de- and re-install. That worked but i lost all bookmarks and saved passwords. Now i lost access to my email account because I cannot for the life of me remember my password. Google recovery keeps sending the recovery code to the same emailadres that i dont have access to. Other recovery stept arent working.

Is there a way for me to find the old saved passwords from before the re-install? Please, i need access because so many accounts on other websites use that email address. Please help me i dont know what to do.

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.

Long time user of sync and now totally pissed because I have to discontinue it because I can no longer trust it. It was so useful.

Syncing between mac and windows desktops. On mac suddenly have duplicate folders appear on the bookmark toolbar. Delete the duplicate entries. Later discover that duplicates and original folders have been deleted. Problem compounds when switching to windows to find sync has very helpfully has deleted these folders there too. There was no way to disable syncing to prevent this. So that means when you do something stupid on one instance, you have no way to prevent that mistake from spreading to other computers. Nice one.

No sync-log found on mac to investigate why the folders where duplicated. so no way to file a bug.

All I can do now is disable sync on all computers. Be nice if there was some kind of roll back.

Thanks to a Microsoft update my PC had to have Windows reinstalled causing me to lose all my apps. I have reinstalled Firefox on the PC but of course, all my bookmarks and passwords are missing. I had set up syncing between my PC and my Android mobile devices (phone and tablet). Can I restore or sync from the mobile device back to the PC? I have searched and found nothing. Even when signed into Firefox on the phone, it does not bring up "Sync" when I go to settings. I truly appreciate your help.

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.

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).

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?

Good day,

Firefox Synchronization restores my old data as soon as I sign in, even though I do not push synchronization.

I have absolutely no power to decide what gets restored. I do not see any possibility to update the data stored on my Firefox profile online.

But the oddest behavior is that I opened a new account from another PC in order to save my actual Firefox data. I then synchronized my data from the first PC with the new account, and this time, instead of overwriting my local data from my new account, it is the data from the new account that got overwritten from my local profile containing the old data.

To sum up things, it seems that:

- I cannot choose what gets saved or restored neither on my PC locally nor on my Firefox profile online.

- When I synchronize Firefox, my data gets randomly overwritten either on my PC locally or on my profile online, without giving me the choice to either backup or restore these data.

Is there any way to avoid this ? And how do I choose if synchronization overwrite my local profile from my online one or the other way round ?

I sync between both my phone and my pc, my phone is constantly up to date on my tab syncing however my pc is constantly lagging behind by a couple of weeks.

Steps taken: exited and reopened firefox clicked Sync Now button on the pc in both the sidebar and in the sync settings logged out of and back into my firefox account on my pc

Every time I try to sign in into my FF account in the browser it fails to connect to sync.

I get to the sign-in stage, it already knows my email so I'm prompted to put in my password then it sends me an email with code which I put in then I am prompted to put in my 2FA. I get signed in on a separate Mozilla accounts page but when I click on the Account icon in the top right in my browser and sync starts it immediately fails and says "Account Disconnected". I noticed that this started happening after I updated my email/updated Firefox to 131.0 (64-bit) Windows. Not sure if any of it is related.

I have tried various things like:

1. Logging in and out (multiple times) 2. Refreshing Firefox 3. Checking that I am not always using Privacy Mode (I was not) 4. Changing Profiles, changing default profiles 5. Reinstalling Firefox

Nothing solves the problem. I am now unable to see any of my bookmarks or anything from my profile because sync never works. I want to add that this is NOT a problem on Android. The issue happens only on my desktop FF installation.

I have been a firefox user for 5 years now and i gave my laptop to repair and it was fixed with an ssd (HP NVMe SSD) to better performance and more speed and efficiency but in the process he rebooted and restarted the pc and now all my data is not there , i have some very important webpages and bookmarks in my firefox browser, i had signed in synced and done everything so that i get the data if something like this happens , however and only 3 or 4 bookmarks were imported and all the search history is gone and new even though i signed in with all my accounts and synced and tried to get the data , i remember that i did everything properly to sync and store the account data,search history,bookmarks and password s and now i am not able to get it and i tried doing it with all accounts i had logged in firefox.how do i get my search history,bookmarks,saved passwords back please tell?

My system was hacked and I had to factory restore it. I didn't write down my login/passwords because I was informed that as long as I had my sign in for FireFox I could restore them on my system.

Alas, I cannot figure out how to do this. I do not have a passkey, a profile or anything other than the email address for my system.

Can you help me? I put all of my important documents in Dropbox and now I can;t access that either.

Anything you can do is appreciated.

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
