I have several friends with the same issue on either PB3 or DP8. Not sure what’s causing it and why it only seem to hit certain installs.

I could not use Beta1 or 2 without crashing. For some reason after a clean install of 1 and 2 and download install of 3 everything started working fine.

One other thing I did was take it off my spinner drive and put it in a partition of my SSD boot drive.

It's been running non stop since the Beta 3 update.
 
Well it’s not crashing. Just not loading web pages beyond the first one (if at all). Most bizarre.
 
HTML content in Mail is no longer rendering even. Looks like this is affecting the entirety of webkit then.
