disable/cleared cache

I'm trying to open a new tab (linkedIn link) from gmail within Firefox 16 on the ubuntu OS. The new page opens, but seems to go into a infinite loop of redirecting/waiting on linkedin. The problem exists in safe mode as well. And under a new loaded firefox and os. However, under the same conditions, but with a different browser Chrome, I have no issues. This seems to be a firefox issue only. No error is given, just a blank page with Redirecting at the top and waiting for linkedin at the bottom. I have tried number of ideas: disable/cleared cache disabled ipv6 disable dns prefetch disable all addons reloaded firefox reloaded os (ubuntu) The problem remains...
