I was going to ream you for choosing your web browser based on its underlying programming language. After all, if you're not having to interface with it as a plugin-developer, what does it matter?
Then I remembered: security. Relying on a human programmer to get every memory allocation and deallocation right every single time has proven to be a security nightmare for the past 20 years the internet has been accessible by the general public. The more safety checks you can push down into the underlying platform/language/runtime/API, the fewer security holes you'll have.
And if you need proof that your standard, mature languages aren't cutting it, look no further than Symantec's recent debacle. If kernel programmers at the world's premiere security firm can't get it right, who can?
