Firefox Community Forum

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.

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.

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 sorry that my letter has caused you trouble but I have to ask you for help to solve the problem I was facing. I forget to save my account Password when I uninstalled the Firefox browser and I didn’t log in to my account at the time.But I’m in hurry and need it too.Can you help me get it back?Thank yo very much! And the website is pog.org

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.

Firefox is installed on my desktop and on my cell. How can I get my cell to show all bookmarks that I have on my desktop? I already synced a few times but no change!

Recently I had un/reinstalled my firefox via snap and apt from linux. I'm signed into my account yet locally I'm not getting data to sync across devices. Any idea?

Hello Mozilla. I am logged on to my Firefox account on a new computer. Although I have logged in, I haven't experienced Firefox automatically syncing my bookmarks and extensions as I did two computers ago to this last computer. I have tried syncing numerous time (pressing the sync button in my account) to no avail. What do I need to do to get this working? Thank you for your time and attention.

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

Historically, I remember when you open the `sync` sidebar and right click on the tab grouping (i.e. Firefox on iPad), it opened a context menu where you had the option to `open all synced tabs`. This seems to be missing from the latest version of Firefox (138), but wanted to check in to see if I'm missing something or if I should downgrade my version of Firefox to get that functionality again.
