TR scripts and content blocking compatibility problems with Firefox

This is just to see if anyone else on TR has had this issue:

Where I work, TR used to work great day in and day out. They were using Watchdog, and I had no problems.

Then, they added OpenDNS to our system to block content based on pre-marked site verification classes with the service.

After this happened, it seems that some of the scripting on TR’s site is causing Firefox 2.0.0.xx to crash sporadically like part of the script can’t execute properly.

Has anyone else had this issue? or is it just my kooky Dell and network and their network setup here?
