The security vulnerability can be fixed by following this:
Type in about:config in the Firefox address bar and hit enter. Type javascript.options.jit.content in the filter box. Double-click it after finding it, to set it to false.

Do you know if this is still required with NoScript installed?

I was thinking the same too, but I really don't have any idea about that.

The bug is in the GreaseMonkey 'Just In Time' JavaScript compiler introduced in version 3.5. With NoScript enabled it's not an issue as no JavaScript can be executed for blocked sites. Of course, if you were to unblock a site that had malicious code attached then you'd be 'kippered.' But that's always true (more or less) anyway.

Thanks for the insight rikmayell

. So, I think we should be expecting a 3.5.1 release soon from Firefox

I imagine quite a few people will be having sleepless nights until they can get 3.5.1 out of the door

Thanks for the info. I only changed back to Firefox so I could use Link Extend. I do wish something similar was available for Opera. I know Opera has a good default security setup but when checking out sites for TSA links there's nothing easier than Link Extend or WOT so I'm a bit stuffed

Downloads are no problem 'coz you can integrate the Dr. Web script but it's so much easier to scan a Google page with red and green dots for the site checks.

Incidentally I made contact with a guy called Suki Takato from Lunascape who was quite chatty until I asked him questions about a security comparison, in particular their own brand surf protection which seems to have died on their website in 2007. The emails stopped coming!

Another one to write off for the time being - three engines or not!

Time to use SandBoxie more often.. Decreasing my browsing speed is not an option (especially with NoScript as well).

I just hope Firefox does not goes the IE way of being full of security issues. That would be sad
