Firefox Support Forum

My Firefox account is synchronized across my personal devices and my work laptop. This has been working fine for a while, until today I got an error on my work laptop that "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile". I suppose this is because it's using version 102.12.0esr, whereas my PC uses version 114.0.

My workplace won't let me just install the normal version of Firefox.

So in my search for a solution, my first hope is that someone can provide some magic solution, maybe?

If there is no such thing, I'd like to know if there's an esr version right around the corner that will fix this?

In the event that I'm all outta luck, what I'd like to be able to do is try to disconnect my profile on the laptop from synchronization, and then force it to open, hopefully it will work and then I won't have synchronization anymore but at least I'll have my profile as it currently is. Can someone tell me how to do this, if it's possible?

What I absolutely want to avoid at all costs is to manually rebuild my profile. Restoring all my settings, including those hidden in about:config, and all my extensions' settings by hand is going to be a nightmare.

Any help is appreciated. Thanks.

I am extremely angry that I decided to move from Chrome to Firefox for a safer browser just for Firefox to lose all my login information I accumulated after some years of use. I am not sure when or how this occurred but I never received any notification that nothing was syncing or I had been logged out. I want all my login information restored. On top of that, I've always had issues with Twitch.tv and any video site crashing. My only concern is my logins being restored.

Hello,

I would like to set different themes for 2 computers signed into my Firefox Sync account, because I would like Firefox to fit in with each system's theme. Would it be possible to do this? If so, how can I set it up?

Thank you, JetFox

Good morning!

Since v112.0.2 my Firefox logged itself out of Sync and will not allow me log back in. When I click the "Sync and Save Data" in the pulldown menu, the page spinner just spins and spins. The login page never loads.

Oddly, I couldn't even login to my Mozilla account here to post this. I had to use "Ungoogled" Chromium to load the page. I've never had any Sync issues with FF, that I can remember. This just "appeared" with v112.0.2 and continues with v113.0.

I did try to access the Sync login page while in Safe (Troubleshooting) Mode... no difference, though; same spinning spinner.

I'm running Slackware Linux on a desktop computer. No other changes have been made on this system other than upgrading from FF v112.0.1. to v112.0.2. This is when the Sync issue started.

Any ideas? Any assitance would be very much appreciated. I could just go to Chromium full-time, but I would not want to do that. I've been a Mozilla browser user for 23 years. The Chromium is only on my system as a backup browser, along with SeaMonkey. Yeah... I have a Seamonkey. :)

Anyway, thanks in advance for any help/ideas to allow me to troubleshoot/resolve this.

Regards,

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.

Hi! My windows suddenly encountered problems and I had to reinstall it, but after reinstalling win and Firefox and logging into my account, none of my data loaded to the new Firefox. Please help, for me, loosing that much of bookmarks and passwords, is just like a matter of death and life.

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome. t

Dear all,

I add to reinstall windows, and every software including firefox.

Previously I checked that my datas were proprely sync.

I just finished the firefox installation, but the sync does not find any of my previous datas... T.T

Any idea please ?

Kind regards,

Thomas

Hi,

I just installed Firefox on my Mac and log in on the account. On new windows device it was always downloading all the addons and importing settings etc.

On Mac I just logged in and nothing happend. Like no any import was made. No any add-on was installed automatically.

Do I have to install everything manually?

Previously FF used only on Windows

I may be misunderstanding the nature of syncing here but my question is this:- I have 3 devices that at various times in the past have been synced but no longer are. Now I want to sync them all again but I want the information that is on my PC, I'll call this the primary device, to by synced to the other two. In other words, I don't want to loose any of the tabs, passwords or bookmarks on this primary computer and I what them transferred to the other two. So, how do I set my PC as primary device? Thanks Chris

p.s. I know this is a different forum but anybody know if there is any chance Thunderbird will be sync-able any time soon?

I use Firefox daily, and I use Sync to save my profile.

Today I had to reinstall Windows for some reason, therefore I had to reinstall Firefox entirely. The profile files were lost in the process, and when I connected with Sync, Firefox installed all the extensions I had before, but it didn't fetch the bookmarks. Like many people, I have hundreds of links in my bookmarks, and I'd like to get them back. Profile files are not here, and Sync couldn't find them? Is there a place where I can see all previous Sync saves so that I can get an old backup (even if it's a backup from days or weeks ago)?

My issue is a bit difficult to explain. When I downloaded Firefox on a new computer, I signed in using my gmail account email and password. I created many passwords and bookmarks. I wanted to sync my phone and laptop to this account but I already had an account on my laptop. My new computer all of a sudden notified my that my log in was disconnected. I signed back in to my account and now it is only showing my bookmarks and passwords that were on my laptop and not my new computer. I only want the things I have added to my new computer and not what was on the laptop. How to I retrieve the bookmarks and passwords that I had set up prior to Firefox disconnecting me?

Fresh install of Kodachi Linux 8.27, added Firefox straight away. New version is supposed to Sync automatically I guess, but it doesn't. I'm logged in to my Firefox account, I got all my bookmarks and synced tabs, but no extensions. This worked fine changing OS's in the past, including moving to Kodachi, Ubuntu, Kali, or Debian, or different versions of Windows. Suddenly Firefox should Sync itself, and it doesn't. How do I get all my extensions back? I had an easy 50 or 60 extensions, and there is no possible way I'm going to reinstall 50 different addons, assuming I could possibly remember what they all were...

Any help (WITHOUT reinstalling every single one)?

Eric

Hello Team,

On the Firefox browser I am unable to find the option where in I can log in to my account so that I can sync my passwords from the old machine.

Kindly advise.

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!
