Firefox won't open, error message"can't find file at jar:file" etc.
"Firefox cannot find file@jar:file:///program files/Mozilla Firefox/omni jar!/browser config. properties." I tried to download firefox and refreshed the desktop link and still no go. Cannot get firefox to browse.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

That issue can be caused by an extension that isn't working properly.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
