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.

FF 129.0.1 Edge 127.0.2651.105 OS Windows 11 Pro v 24H2 Build(26100.1457)

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

Hello,

Couple of days ago I could not start up Mozilla Firefox due to a corrupted file. Naturally, I was immediately worried about my bookmarks, extensions, browse history...

In the end I re-installed Mozilla Firefox -without removing my old folders on C-drive and in AppData- and was able to recover my old bookmarks and extensions just fine.

However, for my old browse history I am not so sure. I have not found a way to restore those.

Could someone help?

Thank you in advance!

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

I just noticed after an update today that the Mobile menu entry (with bookmarks from my mobile Firefox instances) no longer appears in the browser's Bookmarks menu. I can access them from the bookmark manager, but this change seems extraordinarily stupid and arbitrary and is a definite step backwards.

I'm using 128.0.3 (64-bit) for Windows, on Windows 10.

1. I open Firefox normal window. It has some pinned tabs. 2. I open an additional private window 3. I close the normal Firefox window. Only the private window remains 4. I close also the private window 5. I restart Firefox normal window. The pinned tabs have disappeared.

Thank you. Adrian

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.

Cannot access local address 192.168.1.1 which is the address of the GUI interface to my ISP Gateway settings menu. I need it to be able to make changes to the Gateway settings.

I use to get displayed "Advanced" that allowed me to continue forward to get to an "insecure site", only recently that has not been happening (so I am stuck).

Any suggestions, advice, and/or workarounds are appreciated.

Thanks ~Bill

Whenever I type youtube.com into the search bar and hit enter, it says it crashed and i can't get in. Here are all my crash id's by the way

let's keep it as brief as possible.. i have no idea what the hell the degraders of cloudflare are doing, for the past YEARS all sites that required cloudflare worked just fine, and now i lost access to multiple sites on firefox because of the cursed "are you human: captcha loop" i'm looking for extensions, i'm seeking github codes that i don't even know how to execute. the loop keeps demanding me to change the browser to a chromium.. isn't this supposed to be treated as a targeted cyber crime? from google against mozilla? how do i fix the captcha endless loop?

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

It's hard to describe what I mean without an example. I type "tart" into the search bar, and instead of the recently visited Wikipedia page on tarts, the autofill suggestions are full of pages in my history with "start" or "starter" in the title, or even in the URL but not the title. Is there any way to change it so the suggestions only contain the exact words I've typed?

When scrolling down I choose to read an article in a new window. When I open the new window, on the right side, a pop up window appears titled “Join the Conversation” or “More from Daily Express” blocking some of the article’s words. How can I stop this pop up window from appearing? Thanks.

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks
