I've just trashed the prefs and we'll see if that helps. Resetting did nothing. Interestingly, the site that crashed Safari the most was Apples apple-discounts.com.
No, it crashed only 1-2 times. But the the customizations i made to the toolbar were always resetted after a relaunch. A quick google research solved the issue, it was the com.blablabla.safari pref file.
