Ah, that makes sense that the "os" isn't crashing, but that the "Desktop" is. I tried with Chrome, and, guess what? No crash. Then I uninstalled Firefox & the Tor Browser Bundle (TBB), both of which use Firefox, and I removed the ~/.mozilla directory. $ sudo yum remove firefox I re-installed Firefox, and it crashed the desktop again: $ sudo yum install firefox So, now I'm using Chrome (but I prefer Firefox). I must admit I had Firefox honed for protection, with noscript, ghostery, user-agent switcher, dns-flusher, etc. So, maybe those addons were causing the problem (but I did not add anything recently). QUESTION: Is there a Desktop crash log somewhere?
