mozilla firefox hanging all the time

Thanks. Telling it not to check fixes it. Somehow it doesn't make sense to me but then again Scarlett, I don't give a ....

If you want it to be set as default browser after a major release number update, you have to go back and click the Check Now button again. PITA, but it's the only way I've found to make it work with Thunderbird without nagging about the default browser checks.

Well FF & Chrome act the same way on my laptop, with a few tabs open, a few flash video's here and there and it's GUI lockup HARD time. No way to even launch xkill or a terminal window, hard drive access is like crazy when this happens.
I get fed up enough to just power it off abruptly! (Less stressful when the screen goes dark  )
Took the HD out, put a fresh copy of XFCE on an old 60gb SATA drive, got everything working OK, no lockups (yet) with FF!!!
I'm thinking KDE just doesn't play well with my hardware or something but I have no compunction about wiping the KDE install off my original drive & doing an XFCE install if further testing goes smoothly.
JMHO, YMMV. ;-)
