> * Disabling IPV6? Really? From what I have read about the slow roll-out of IPv6 is because network operators just don't know how people are going to exploit the expanded address space. Email spam is a good example. With a server on IPv6 I get a block of addresses which means I can email out from any of a literally thousands of addresses. Email servers need to be coded to be able to blacklist that block rather than a single address. Where ever blacklists are used they've really got to be adapted for groups of addresses. The question is can you be sure Firefox has catered for all security concerns surrounding a new technology? If you are producing a security product, you don't use the latest and greatest technology.
