I have both Win7 and Win10 on separate drives. I have been migrating from 7 to 10. From all appearances Firefox on both OS's are sync'd. I have asked for my passwords to be sync'd, yet they have not migrated to Win 10. Bookmarks have so I know something is working. Any advice? Thanks Chris

Yesterday, I noticed after I closed and re-opened Firefox, my browsing session was completely gone - all my tabs and windows, my entire browsing history, website sign-in status, all completely gone. I've been troubleshooting since then.

I've noticed that the 'sessionstore-backups' folder in my profile folder is missing. When I open Firefox, this folder is created and Firefox writes some data to it, but Firefox seems to delete the folder as soon as I quit Firefox. Firefox should not be doing this. My Firefox is configured to open previous windows and tabs, and is NOT configured to wipe any browsing data of any kind when it closes.

As a sanity check, I spun up a Windows Sandbox (briefly, it's a clean, isolated Windows environment) and installed Firefox there. I also enabled the option 'Open previous windows and tabs'. Firefox behaves normally - it re-opens the tabs/windows I had open when I quit Firefox. Great, that's what I expect. The trouble starts as soon as I sign in to sync. After signing in to sync, and letting the initial sync process complete, I open a couple of windows and tabs, then quit Firefox. Firefox begins nuking my browsing session again - the 'sessionstore-backups' folder is erased, and next time I start Firefox, all my windows and tabs are missing, and my browsing history is missing.

So, at this point, I'm assuming something in my synced data has become corrupt. I haven't installed any new extensions lately. I haven't changed any of Firefox's settings that would cause this to happen. The only thing I have done differently lately was enable Firefox Sync in LibreWolf and sign in to sync there. It seems like this session-nuking trouble started after I signed in to sync in LibreWolf. I assumed, since LibreWolf is a fork of Firefox, and because there were no warnings or indications the feature was incomplete/unstable/experimental/etc., that it would just work, that it wouldn't cause any issues. But it seems like it has caused issues. I checked LibreWolf's issues tracker for anything related to 'sync', but I didn't see anything noteworthy.

I've been using Firefox and Sync for numerous years without issue. This session-nuking thing started yesterday.

I use Firefox in a few places, and based on what I saw happen in my Windows Sandbox, this session-nuking issue is going to happen in every Firefox I'm signed in to as soon as it has a chance to sync. Obviously, I do not want this to happen.

What can I do to determine what the issue is? What can I do to check if something in my synced data has become corrupted? What can I do to reverse it? I'm not opposed to completely wiping/resetting my synced data, but I'd rather not if I don't have to. The only thing I would lose sleep over is my bookmarks, but I know I can export them. Are there any debug logs I can enable/look at? Anything I should look for in Event Viewer?

Thanks.

Hello, this is josh, I have a dedicated website for my business and I use Firefox Brower. The problem i'm facing right now is the website isn't loading properly in the Firefox. Website isn't showing image and proper site. However, when i try to open the site in the other browser, it looks fine. what should I do, you please guide me.

Hiya good citizens of the internet 👋

Please help me recover my bookmarks 🥺

I've gone through every single support article on this topic and tried everything suggested and still no luck. This is my hail mary.

How I got here I needed to do a full wipe and reinstal of my macOS; this was conducted with the help of the Genuis bar. Upon reinstalling Firefox, I signed into my account and my bookmarks are all gone, records of them empty.

I should also note that nothing else ported over. No passwords, no browser extensions. Nada. The passowrds and extensions aren't a big deal. I use a 3rd-party password manager and can easily re-download the handful of extensions/widgets. But I heavily relied on bookmarks for both frequently visited sites and ones rarely-used which I knew were important for future reference. And I cannot remember 80% of them...

What else I've tried other than what's suggested in help article:

• Because I did not check to confirm which Firefox profile I've been signed into for ages and ages before doing the reset, I thought maybe I had just signed into the wrong one. I proceeded to try every other email address I have, including two from my old workplace. None of the other 5 emails had profiles created. I know this because it prompted the sign up userflow; create a password, etc.
• But I also know for a fact that the bookmarks were saved as part of a profile because I used the profile sync feature to auto-port all my bookmarks when I first got this Macbook a year and a bit ago.
• The folders where bookmark backup info is stored locally are empty... Clearly, it wasn't stored in my icloud documents (that's on me for not double-checking)
• I checked my other device (mobile phone) to see if I had firefox downloaded and was signed into the same account as the original, with the bookmarks still visible. Of course I didn't. I only use Safari on my phone 😭

""Grasping at straws: the only other things I can think of""

• Is there some way of linking my MAC address with my IP address and using those to triangulate the correct profile?
• Because my computer got wiped and nothing is saved locally, my only hope is that my bookmarks are floating around the ether. If so, I just need to figure out how to find them.

Any and all help/suggestions are massively appreciated!!

Thanks in advance,

Lauren

So, my old computer recently broke, but I luckily recovered all my files. I was re-downloading Firefox onto this computer, but my bookmarks and add-ons and stuff won't sync. When I searched for the solution to this, I saw someone having a similar-ish problem (https://support.mozilla.org/en-US/questions/1403774#answer-1563248), but they just said they had to wait awhile for it to sync. Now, I have a couple questions that I can't seem to get the answer to:

1. How long does it take to sync my data? How long did that person have to wait?

2. What if it never syncs and that person just got lucky? Is there some sort of alternate way to fix this faster?

I'd really appreciate help on this topic, but I'm not the best with computers. If anyone has had this problem, and figured it out, please let me know! I had a lot of bookmarks and a good amount of add-ons, I really would like to not lose those.

I have two notebooks with Firefox (NB1 and NB2). NB2 rebooted and Firefox restarted losing all open tabs; now I would like to bring the tabs from NB1 to NB2; both have synchronisation enabled, but when I go to ‘Settings, synchronisation’ on NB2 it says ‘Synchronising in progress’ and nothing happens. I've also tried going to NB1 and sending a tab to NB2; I select NB2 and nothing happens.

When you check the image, you can see two "HOME" entries. This is an issue I discovered after uninstalling and reinstalling the Firefox browser and using Sync.

HOME is my PC, and this image was screenshot on my laptop.

Additionally, the Sync for these HOME entries is not functioning properly. I tested this by opening several sites, and while Sync works well from my smartphone to my PC, it doesn't sync properly from my PC to my laptop.

Does anyone know how to solve this problem? I tried rebooting my PC, but it didn't work out.

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!

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

I have a question regarding syncing. Is there a way to remotely remove all synced information from Firefox on a particular PC without actually accessing it? For example, if I sync my home PC Firefox with my laptop or my work PC. Then, one day, for some reason I no longer have access to my work PC, and all of my sensitive information is there. Or if I lose my laptop, or if it is stolen... Is it possible to remove all sensitive information from a remote synced PC? Alternatively, is there a way to remove all synced information every time I close the browser? This way I can remove a particular PC in my Firefox account and once the browser is restarted at the remote location, the data will no longer be pulled and synced. Can this be done? Thanks in advance!

I have had several computers and a phone synced with Firefox. Recently, my mac book had to be wiped and OS reinstalled. Since then I have been unable to sync to my Firefox account on that laptop. I enter my standard email and the same password as on my desktop, but get an error stating, "Incorrect Password".

Following suggestion from an older thread with the same problem, I installed a nightly build on my desktop and tried to log in with that, unsuccessfully. Same problem. I used my same email and same password, but the nightly build version of Firefox reported the error, "Incorrect Password".

While thinking about this, I checked my newish phone and found it was not synced either. Using my email and password, I was unable to get it to sync. However, I was able to sync the phone using the QR code. So my phone is now synced to my Firefox account.

I really want to get the laptop to sync to my Firefox account and am mystified as to how to track down what the problem might be.

I recently had to factory reset my computer and had to download and sync my firefox account all over again. It's been a week and firefox is still syncing, none of my bookmarks, add-ons, history or top sites on the new tab are showing up. Thankfully, it appears that most of my passwords have been synced.

I've read some other threads for tips and can confirm that I don't have this account logged in to other devices and I don't have a vpn or proxy running. I am able to obtain the sync logs but I have no idea how to read it.

How can I make the bookmarks, add-ons, history and top sites sync faster?

I was signed in with FF and synced all data. I needed to re-install Windows, after installing FF on fresh windows and logging into FF account - nothing is synced. What have i've done wrongly?

my older asus laptop had a critical failure and I needed to get a new computer and to my understanding when you have had a Firefox account for as long as I have you should be able to sync your whole account to a new device to my dismay that is not the case and I have years of bookmarks and history on my account urgent fix would be appreciated.

My Firefox account and associated passwords were left open on another notebook. I have now changed my Firefox sync login password from a different PC and signed out of other devices. Can a user on the previous PC sign in with a password that is saved in Firefox?
