Due to increases in sensitive data being lost they clearly want all possible sources of said data to be encrypted. This may or may not be overklill depending on your opinion but one thing is for sure and that is that it's their decision to make.
If your not happy having your personal computer encrypted (And I know I wouldn't be) the simple solution is don't use it at work, use a work computer. If the requirement covers you checking webmail from a personal computer at home, where you will have access to sensitive data, the solution it to not check your email from home.
If you are required to check email from home and are not happy to have your whole computer encrypted then your employer should provide you with a company laptop which they can do what they want with, encryption and all.
Got to say this is so to the point.
Many time I've made some good clean kills followed by a lot of "OMFG nice wall hack/Aim bot/cheating...." and I'm not even that good.
There are far more competent player out there make far more constant kills than me and its not cheating, Its just good reflexes and hard work.
My comment is to just get over yourself and have fun.
For the love of fuck.... the memory leak that most people seem to think plagues Firefox is in fact a caching feature and not a memory leak.
Firefox stores a cache of pages in memory. This can be turned of in about:config if it's that much of a problem for you, but will dramatically reduce the speed that you can click back and forwards through pages.
