well I set it to download windows updates but it did not do the update - makes me mad - dang thing - now I work a nine hour day presently so wanted it to do its thing then as I use it at night till about 8 or so then real early at like 3am - so it says failed to install version 1709 so I am going to try again tonight now the thing is I have a couple of different opinions on how to uninstall the non working firefox before downloading and installing it again - and a couple of them mention that I should have a installation folder in the Programs file or the Programs (x86) in the Mozilla firefox folder and I have an uninstall folder but no installation folder - so not sure how to proceed

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved.

So I have looked for solutions on the Edge browser and tried renaming the profile, restarting and trying to launch and no browser - safe mode will not launch either and if I open task manager I find it running as a process - once I right clicked that and ran a troubleshooter about compatibility but it did not fix the issue

What did you rename? Your Firefox profile?

Regarding Safe Mode, do you mean Windows' Safe Mode (disables numerous startup programs/services) or Firefox's Safe Mode (disables extensions, hardware acceleration, and various customizations/features)?

I wouldn't bother with the compatibility troubleshooter....

Possibly you're encountering this issue:

A Recent Issue for 64-bit Windows Users with 64-bit Firefox

Before Firefox 56.0.1, users of 64-bit Windows generally were using the traditional 32-bit version of Firefox. However, newer versions may switch you to the 64-bit version.

We received a number of puzzling reports of Firefox either not starting or not loading any pages after this migration.

One user discovered that Windows was silently killing Firefox at startup and recording it in the Windows event logs (you can view event logs using the Event Viewer). Based on one of the reports in the log, we were able to trace that to an out-of-date Logitech camera driver, of all things.

By now at least six other users reported that uninstalling or updating the Logitech camera software resolved their problem as well.

Do you want some assistance in looking at event logs, or do you have such a webcam?

If the investigation doesn't yield any solutions, it is worth trying a return to 32-bit Firefox.

While normally this kind of change is seamless -- the installer detects your existing data and preserves everything -- you might want to make a backup "just in case."

ok I was told somewhere that I can not currently find all who have tried to get me back in the flow- that one thing to try was delete or rename the profile so a new one would kick in - sl I thought the profile was in the Mozilla firefox folder but it is not so I do not think I renamed the correct file - anyhow what do I point this event viewer at? I used to be so techy and up to date - not just do not have time for nonsense - back in the day we wrote programs that were compact, efficient and elegant - all this user friendliness, redundancy and bs are so annoying - sorry small rant - sure appreciate the help All who have tried to help I sure appreciate it and I am working slowly thorough the suggestions and will let you all know how it goes now going to look for a Logitech on here and see if that is the bug

If you renamed the wrong file and do not remember which file that could now be a issue. Which both of my previous posts will fix.

Create a new profile as a test to check if your current profile is causing the problem.

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem. Never work with original files.

Then start in Safe Mode before do anything more and TEST : SAFE MODE

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

In Firefox Safe mode these changes are effective:

• all extensions are disabled (about:addons)
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored (chrome folder)
• default toolbar layout is used (file: localstore-safe.rdf)
• Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
• hardware acceleration is disabled (Options > Advanced > General)
• plugins are not affected
• preferences are not affected

TEST

No see I can neither launch Firefox nor safe mode firefox - I am sorry I guess I was not clear on that - they will not launch and then if I look at task manager I see that the process is going on, so I can end task well I did scan the crap out of this , update BIOS, now Windows is updated final despite the fact that I tried three different times to change the active time so that it knows when to update things - refuses to change like a stubborn teenager (or toddler) so the time to uninstall firefox and download and reinstall
