[amd64, feisty] Firefox hangs when browsing some sites, even in safe mode

[xtsbdu3reyrbrmroezob]

Binary package hint: firefox

I occasionally happen to make Firefox hang on my Feisty amd64 setup. It was working fine until a month or so ago, maybe longer. Anyways, I am able to reproduce this 100% with some sites and all latest Feisty updates up to a few days ago. I am not sure if this is related to nspluginwrapper, but it may be.

$ firefox -safe-mode "http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=78604830"

.

Can anyone else reproduce this?

This was actually due to an issue with nspluginwrapper on amd64...
