My Firefox browser will not open no matter how many times I click on it. Since most of the articles I could find discuss working from an open Firefox browser they were not helpful.

Should I uninstall and then reinstall Firefox? And can I save my personal information if I do that?

I got as far as finding this link to my personal folder, but I honestly do not understand what I am supposed to do with this information:

Perhaps you're encountering this issue for several months ago:

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 Based on one of the reports in the log, we were able to trace that to an out-of-date Logitech camera driver, of all things.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?

Does Firefox give you an error message, or does it just seem to die quietly when starting up?

more options

Neither. There is no error message, or any message, and the browser does not even start up. It just refuses to open even a little.

Thanks for the info! I downgraded to the 32 bit version of Firefox and that seems to have done the trick. Thanks again for your help, this was a very obscure problem!
