Was crashing on the webpage http://www.epinions.com/t-hp-6110. Been crashing for a week or two on various webpages. Maybe 1 in 100 pages. Got it to crash by clicking on links in page. Might take a couple tries to get it to crash though. Also crashed when by loading page to gather info to write this. Crash never leaves a crash report.
Newest versions installed.
NoScript 1.9.2.9
Installed latest build to see if it would go away, and it didn't.
