This is the first time that I've had significant trouble with a desktop Mac since I purchased one in 2008.

Basically, any trouble that I've had prior to this has been negligible and easily resolved.

I don't recall, exactly, when these two issues began. Possibly months after upgrading to Catalina. I'm combining the two issues because I believe that they be related.

The first issue that I noticed was with Firefox (probably 70.0.1 and slightly earlier). I would have two or three tabs open, and go back to one of the other tabs, to find a completely white screen with a grayish colored pinwheel. I'd then go back to one of the other tabs to find the same thing (that was previously not happening. Then, I'd close all the tabs to open a new one in order to try starting fresh. No dice...same shit.

Following this I'd select > Firefox > Quit Firefox. Minutes later it's still not quitting indicated by the black dot under the icon of the launch bar. So, I'd go to the apple icon > Force Quit > to execute that. Finally, it would quit. Minutes later I'd try to reopen Firefox and the icon would just keep jumping up and down from the launch bar and nothing would happen.

I guess I'll just have to restart the computer then, right? Apple icon > Restart > several minutes later nothing would happen except for another grayed out pinwheel. So, I just performed a hard reset by holding in the power button on the back left of the screen. Waited several minutes, started it up again by quickly pressing the same button.

After logging into my account, I'd get the usual text box saying that 'Your computer was restarted because of a problem...blah...blah...blah'. All of the aforementioned took many minutes.

Now, when I try to shutdown my iMac it just goes black and then returns to the login screen with a brief black screen, in several languages (Chinese being one of them), that 'You have restarted your computer.....'

And Firefox keeps fucking up as described above. Going to about:crashes registers jack shit.

It's a never-ending loop of Mac/Firefox bullshit that's driving me fucking nuts.

    If this is the screen you’re seeing, and it’s happening repeatedly, it sounds like you may have a hardware issue. Maybe a faulty RAM DIMM? If you have an Apple Store or computer repair shop in your area that services macs, I’d recommend taking it in for them to diagnose hardware issues. Alternatively, you could try Apple’s built-in diagnostics.

      Yes! That's the screen I'm seeing. Unfortunately, I don't since I live in a remote area. I'll try this and see what happens. Thanks for your help!

      I ran the test and it came back with ADP000: No problems found. And yet I'm still having the same issues that I've described in the OP.

        Have you tried resetting the PRAM? This is one of those fixes for "computer is being inexplicably weird" issues. Otherwise it really does sound like a memory issue. Are there any steps you can do...

        Have you tried resetting the PRAM? This is one of those fixes for "computer is being inexplicably weird" issues.

        Otherwise it really does sound like a memory issue. Are there any steps you can do to reliably duplicate the problem or is it just a random occurrence that sneaks up on you?

          This is something that started happening about two weeks ago and has happened once or twice per day since then.

          Before I reset the SMC I shut my iMac off. Surprisingly, this was the fastest shutdown experience that I've had for months. I don't know why my iMac suddenly started shutting down properly and fast.

          I've reset both the SMC and PRAM/NVRAM. I guess I'll have to wait a few days to see what happens next.

          Thank you for the link to the instructions and all of your help!

        Well I’m out of ideas besides searching around to see if anyone is experiencing similar problems with macOS/Firefox.

      That happens when one of Firefox's content processes crashes; the tabs it was responsible for doing all the work of go white, until the dead process gets restarted, while the rest continue to work. It doesn't always get restarted promptly.

      Flaky memory could definitely cause this too.

        When I go to about:crashes there is nothing there. Would you happen to know more about this issue or how to further diagnose it?
