Update:  I restarted computer this evening & Firefox opened.  I got some type of Browser message that stated Firefox was having trouble restoring tabs.  What I was doing AT THE TIME of the crash is looking at my Yahoo Mail in READER VIEW.  I then clicked on the narrate button on the left side of the page.  The narrator started to read only parts of one of my e-mails.  The computer generated narrator was doing an absolute terrible job of reading the e-mail to say the least.  That is when Firefox crashed.  
 I wanted to say that I want to give you guys any help I can & I love Firefox!  Any help you could give me will be appreciated.
 P.S.  I tried to share data by clicking button below this details box.  I don't know if it "worked" or not.  Let me know if it doesn't.

Firefox would not start after crash. It worked fine for a couple hours or so, opening & closing browser. I let computer sit idle for couple hours or so & would not start.
