Firefox not opening after Windows 10 Security Update

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 download some documents and save them on my hard drive. When I open them, it opens Firefox instead of opening Acrobat reader. I need to be able to work offline with them in Adobe - I do not want the HTML version. This has only started happening recently. If this can't be solved I will have to try another browser. I am a reasonably savvy user but I am not a technical expert. Thanks for any help going - I am desperate. They all seem to have saved themselves as HTML documents. Any ideas?

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?

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

When my Google calendar loads in Firefox the reminder entries don't display by default. All other calendar entries such as appointments, birthdays, etc. display just fine. To make the reminders display, I have to click on the calendar main menu (the three lines) and check the box next to reminders. Then the reminders display fine. However, the next time I start Firefox the reminders once again don't display. Once I have the reminders set I save the settings, but that doesn't help. I don't have this issue with Edge or Chrome. Has anyone else run into this, and if so, have they been able to fix it? Richard

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.

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!

Firefox Will Not Open Despite Trying Several Solutions (Windows 10)

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 to curate and compile sheets of announcements for a local humanitarian service provider forum. I do this by sifting through my Office 365 emails, and double clicking those that contain announcements so they open a window, then sorting the windows on a second screen, then read them, summarize them, file the pertinent information with links for my summaries, and when I get a page of them, send them out. I usually start with about 15 announcements on my other screen, and it takes me some time to get them all sorted and cascaded in order for the curation.

Some of them link to PDFs which Office 365 doesn't always preview and I click download, and this used to open them in the main browser window in a new tab, where I could read them and then save them. Recently, this behavior changed and they now open right in the window the email is in, with no bars of any kind or tabs to get out of them again. I hit the stack of pancakes button, and it had a tab marked Exit, so I thought that would exit me from the view.

Instead, counterintuitively, it exited me completely from FireFox, closing all of my carefully cascaded windows of announcements, and my main browser window with Office 365 in it and everything else.

Thanks a bunch. 1) What was so wrong with the previous setup that you needed to change it? 2) How for the love of whatever the author of this new "feature" was smoking, do I get it to revert to the email or is opening these attachments by "download" no longer possible without punting the whole thing to exit? 3) Does this mean I need to permanently disallow Firefox as the browser for all my PDFs or is there some way of doing something non-fatal to my work on a per-boot basis?
