I have Firefox 4.0.1 & MacAfee SecurityCenter 11.0 running under 64-bit Win 7 Professional SP1.
For the past few weeks Firefox has been occasionally crashing for an unknown reason. About 15 minutes ago I received a Firefox warning that McAfee ScriptScan for Firefox 14.4.0 was known to cause stability problems and advised blocking it, which I have done. Firefox have added ScriptScan to its blocked add-ons list, dated 3 October 2011.

Thanks for reporting this. It is a known issue and is being worked on. I moved this thread to the ViruScan section where you will see several similar threads.
It may or may not be relevant, but I use the Firefox script-blocking Add-on, NoScript.
This scriptscan issue has been reported now for a couple of weeks by various people and I have alerted my sources at McAfee about it.
Just got this from McAfee...
I’ve asked Support to push an FAQ out ASAP, but meanwhile:
1) It’s NOT a security issue
2) It’s a decision made by Mozilla based on crashes that have been reported to Mozilla
3) McAfee is aware of it, has a bug filed and is working with Mozilla to address the problem
4) Until it is fixed, the primary workaround is to re-enable the ScriptScanner. Alternatives include use another browser for now (with most browsers you can import bookmarks and homepages). Also, SiteAdvisor 3.4 will provide *some* overlapping protection, specifically for scripts run in iFrames on webpages
