Sometimes I get this blank page with only the following message:
Prefetching is not allowed due to the various privacy issues that arise.
This usually happens when googling for an addon and clicking on the link that goes directly to an addon page. I am suspecting this is due to some combination of FireFox+Google+Squid, but I have not confirmed exactly what mechanism triggers it.
If you tell me what you do not want us to do, I can probably tweak my FF or Squid configuration to adapt accordingly.
