I have just upgraded my pc, new motherboard, cpu, ram and m.2 drive, of which I made a clone of my previous windows installation, on first opening it had the previous session, where i had opened another tab while it had the restore session tab open, this usually isn't a problem.

However it lost the session to restore, I have tried a complete copy from %APPDATA%/Roaming/Mozilla over to the new system, but to no avail, the session can still be restored on the other setup currently, which I had copied over manually to try resolve.

I even tried to copy the files 1 by one to test from sessionstore-backups and renaming to sessionstore.jsonlz4, however upon opening firefox, it rewrites the 9.5MB file with a 2KB file and I have no session to restore.

Is there a way I can resolve this as I don't remember all the tabs, I do need to go through them, but several I had open to return to.

Any help would be appreciated so I can get these back and go through them, would be easier than trying to copy all the URL's one by one to check them

Hi all,

I'm getting a page asking for validate reCaptcha on every Google search.

Using Chrome or Edge on same computer(Win10) and same time I don't receive the page validation.

On my network I have the same behavior on others Win10 computers. All my computers have Kaspersky installed.

What I have to do? Some different setting?

Waiting for a help and best regards,

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

Hello,

With the previous version of Mozilla Firefox, I was able to preview my work by passing privacy.file_unique_origin to false.

Now with the new update (95.0), it doesn't work anymore.

Can you please provide a solution to this issue?

Thanks in advance

I downloaded a Windows 10 update last night. It was Security Intelligence Update for Microsoft Defender Antivirus - KB2267202 (Version 1.361.793.0). Now, I cannot open Firefox. When I click on Firefox for around half a second I see an error box that says "Open Firefox in troubleshooting mode?" and nothing else, with no option to click yes, then the box closes. The same thing happens when I try to run firefox.exe -p to change profiles. I also cannot open Tor Browser, and I am wondering if there is a connection. I have tried uninstalling Firefox using the uninstall tool and reinstalling but I have the same issue. I uninstalled the windows update and opened Firefox. This time, it had the "Open Firefox in troubleshooting mode?" box but I could actually click on the yes option, and Firefox opened. However, when I clicked on the option to get a fresh install and remove the extensions, Firefox closed and I am back to the same place of it not being able to open again.

I have loved being a Mozilla-stuff user intermittently since teaching on Netscape 1.1, and now am making Firefox 98.02 my default browser. I like both Safari and Firefox, and sometimes use them simultaneously for two accounts on the same service (not right now). My physically pristine 2015 Mac cannot install OS's past the 10.12 I have, so Safari is failing. But I am exasperated at runarounds when trying to set up this Firefox account. I used the emailed verification code and seemed to get in, but got the red-box message "This account... administrator... error." I cannot tell whether the site is letting me use it normally, but I think not. I just spent an hour in help forums. Geesh, tech complexity has mushroomed since my LAN work in the 90s, and you volunteers get to cope with inarticulate queries like mine!

Hello, Last few days Firefox keeps automatically downloading strange files like mLZrOMIV.htm icFSREgF.htm

They are 0 bytes, empty when I open in notepad and if I right click in download section and select copy download link I just get about:blank

I checked PC for viruses using Eset Online tool and Windows defender. No problems.

Has anyone run into something like this?

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

Certain site show what looks to be Chinese writing in the menu and description. Videos for those site will not play. This just happen today. Is there something going on with firefox? what would be the best fix?

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

I have this box that shows up over the top of any video application on my firefox browser since my most recent update. It doesn't appear on other browsers. How can I remove it?

The root problem is that when I try to open a movie in a web browser, I get the message "Oops. Your web browser is no longer supported. " see attached.

1370719 had a response that made no sense to me.

Is there anyway to fix this issue?

When I open Facebook with Firefox all of the images in the FB session are blank, and they will not open in the usual manner. Also only about 1/4 of the FB session is displayed.

When I use Edge I have no problems at all, so I have to assume that it is FF and not my computer that is at fault.
Please advise.

Is there any to make Firefox automatically restart a new session (loading the start page) after a crash, without any prompts?

Context: This is for a disabled person who cannot use input devices: I start her computer every morning before going to work and load a long Youtube playlist of videos, so she doesn't have to do anything. But if Firefox crashes 5 minutes after I left, she cannot restart anything herself and has to wait until I come back.

Any ideas?

Hello,

Starting Firefox 97, opening a file involves downloading it the same way as if I choose to save it. It results in both Download folder and downloads list in the browser being polluted with a million of files I only wanted to open once with a specific app (pdfs, xls, m3u etc.).

Previously Firefox was using a hidden internal folder for saving such files and deleting them later, so Open In App really meant "open, do not save locally". Now any option just means "Save the file to the Download folder and let it be there forever".

How can I fix this unsuccessful UX decision apart from downgrading to an older version?

Thank you.

P.S. "If you dislike new features in the latest version of Firefox, your first reaction might be to go back to the previous version. Rather than downgrading, try getting used to the new features..." is probably the worst suggestion you can possibly give to someone with their workflow broken by a sudden update they can't decline with a feature they never asked for.
