I received two updates today and the outcome was an unstable Firefox browser. The first update was from Firefox 12 to 13. This went well, as far as I could tell.
Later on today I read about a critical update for Adobe Flash, to version 11.3.300.257, which I applied.
Ever since, Firefox has been locking up, requiring the use of Task Manager's End Process key. I decided to investigate and try stuff and the outcome was that I had to disable the Flash Plug-in for Firefox to stabilize my browser.
If you have updated to Firefox 13 and the aforementioned version of Flash and your browser is freezing up, open it afresh until it is stable. Then click on Tools > Add-ons. Select Plug-Ins from the links on the left. When Plug-ins page loads, disable the Adobe FLash Plug-in and restart the browser.
This fixed it for me. Flash videos and applets all continue to function just fine! I don't know why yet, but will get to the bottom of this soon.
Note, that the Flash update fixes 7 critical vulnerabilities. I expect that if they are aware of the instability this update is causing, Adobe will re-issue that update with a patch.

Okay, I have discovered that the videos I can watch are no Flash, but HTML 5. When the Flash Plug-in is disabled it is really off. I failed to restart the browser before and Flash was still active.
I will report back here if Adobe or Firefox receives an update to patch this problem.

I have apparently esolved this issue. Here's how.
I correctly Grokked that since I had rolled back to Firefox 12 and it was still crashing when loading pages with Flash content, that the recent Flash update was at fault.
I proved this by disabling the Flash Plug-in and going to the About Flash page, which loaded fine without Flash in the browser.
I re-upgraded to FX 13, with the same results. I reviewed the events of the day and concluded that I had a bad upgrade installation of Flash 11.3.300.257.
I uninstalled all instances of the above version of Flash (only one present was in Fx and IE formats). I downloaded the Flash installers for Firefox and Internet Exploder. Closing the browsers I ran the downloaded setup files and installed Flash anew.
Since then, when I go to a web page containing Flash content, it opens and loads just fine.
Epilogue:
Flash was the culprit, but only in as much as the upgrade installation went badly for me and dozens of others. Uninstalling and reinstalling Flash resolves this issue, with the associated mandatory reboots.
