So how did you firefox update? And what version are you now 32bit or 64bit and what was the previous version?

Type about:profiles<enter> in the address bar. How many profiles are listed? How many should be there?

I did not update Firefox. I attempted to update and Firefox crashed. Now I have no access to firefox and no way to fix my mess that I can figure out. Thus my initial question. I now have no version of firefox. I'm pretty sure I was using 32 bit when the program crashed. I've been using firefox for over 20 years and now I'm cut off.

FredMc D.: none of the four links you sent does any good. I'm currently not able to follow any of them. My computer is not responding in a way that makes sense when I try to follow those links.

I'm going to once again attempt to delete Firefox entirely. Then I will wait a day before attempting to reinstall. When I have deleted and waited just a few minutes to reinstall, I get the same message about my profile is missing or inaccessible.

I don't know why or how the update I clicked was corrupted. If Firefox is this much trouble and untrustworthy I may be forced to give it up.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

I just went to a non Firefox help site on line and quickly got Firefox back up and running.

However, I'm now missing the pull down tabs along the top of the screen that I once used for bookmarks, editing, printing, etc. I can't figure out how to reestablish those pull down tabs. Any ideas w/ that problem?

thanks for your help. I figured out how to get the bar back. I may be good to go now. I will not click on any Firefox update buttons again.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
