Firefox crashes whenever I try to shut it down, or turn off computer. Now all my saved tabs are gone too.

I am on an iMac running High Sierra 10.13.6. For the last couple months whenever I try to close Firefox it either crashes or I have to force quit Firefox to make it quit. But on restart tabs have been restored, or I have been able to bring them back using "restore tabs".

Two days ago my wife was using my computer (I was out of town) and when she finished she tried to turn off the computer. She got a message that Firefox was not closing so the computer could not shut down, then a minute later (without her doing anything) the computer did shut down.

I got home todaty and started the computer. Opened Firefox and found all of my saved/open tabs (~25) were gone. No "restore tabs" option available.

Is there any way I can locate and restore the missing tabs? I've looked through some posts in Support, but all of the crash issues I found were of a different type. And it would also be really nice if I can get Firefox to close normally again. Are there any plugins that commonly cause this kind of problem?

Thanks in advance for any help!

How do I get Firefox to recognize the profile that is in my Library on a Mac? I didn't touch it; did nothing to it, but when I tried to open Firefox it suddenly was missing. And your Help system HAS WAY TOO MUCH INFORMATION IT SO AS TO BE NOTHING BUT CONFUSING. I AM NOT A CODE JOCK OR A WEB DEVELOPER OR SOMETHING. END RESULT: YOUR HELP SYSTEM IS USELESS!!!!!!!! I even tried deleting my current Firefox and downloading a fresh app. SAME THING! Please answer back with a REAL person, not some canned menu of HUNDREDS OF OPTIONS. Or, I will simply not touch anything from Mozilla again. Now that is SIMPLICITY!!!!

Firefox keeps crashing, sometimes individual tabs, sometimes the whole thing. The constant "crash reason" given in the reports is: EXC_BAD_ACCESS / KERN_INVALID_ADDRESS.

I'm using a macbook, mid-2010 upgraded with SSD and 8GB RAM. (Which may be the problem right there.)

My only extensions are Facebook Container, OneTab, Reddit Enhancement Suite, and uBlock Origin. Only plugins are OpenH264 Video Codec, Shockwave Flash 32.0, and Widevine Content Decryption Module provided by Google Inc. (no idea about this last one).

Any ideas?

(My understanding of the inner-workings of computers does not run terribly deep...)

To upload photos to Instagram I changed my user agent to replicate an iPhone. Now I can't change it back. I can't get through to your site on the effected computer with the changed browser. Thus, I can't download a new version of Firefox. I understand there may be a "revert to original" command somewhere, but I can't find it. HELP! What do I do? Thank you very much for your assistance,
