Yes, I'm using a pretty old build of Firefox and yes, I'm still stuck with Windows Vista. The former fits my needs and I don't want/have the time to upgrade, the latter is a pain in the ass that I hope to replace with Windows 7 asap. And yes: I don't give a single **** about "design" or "innovation" on web browser UI and such mundane stuff
You "don't have the time to upgrade" your web browser? That is one of the weakest excuses I've ever come across. If you used Chrome you wouldn't have to worry about updates as they're automatic and Firefox will soon be doing the same. By using such an old browser you're more vulnerable to security exploits, have outdated support for web standards and are lacking the significant performance enhancements made in up-to-date versions. It just strikes me that you're being stubborn / non-conformist for the sake of it, not for any legitimate benefit.
Your position seems deliberately confrontational, especially when you pre-empt criticism by stating you "don't give a single **** about "design" or "innovation"".
