A large part of the purpose of a Firefox beta is to gather feedback on new features. If new features can't be gradually rolled out in betas, then when can they be?

*RC*s should be stable, with no new features. "Beta" just means "it's still being worked on, but you can out this fairly stable version".

Did you file a bug?

Sounds like you're running lots of crummy add-ons, or you're leaving pages open that are doing lots of bad Javascript stuff (e.g., never letting go of objects so they can be collected). That's the main cause of memory bloat.

I'm using vertical tree tabs in FF4 right now. You might need to disable add-on compatibility checking, if the author has been slow doing so.

If it doesn't stop projectiles, but stops the enemy seeing you, the term is "concealment", not "cover".

Isn't it a little disingenuous to say "finally" when the bug was discovered last month?

That it was introduced 17 years ago doesn't mean that Microsoft has been tardy about fixing it...

Many guns don't have safeties: neither of my wife's guns do.

I moved from the UK to the US about 5 years ago. I feel perfectly safe at home with a gun. Objectively, subjectively, and statistically, I am safer here with a gun, and I'd like to keep it that way.

Um...

"£400 million ($668 million) will be spend on installing and monitoring CCTV cameras in the homes of private citizens. Why? To make sure the kids are doing their homework, going to bed early and eating their vegetables. The scheme has, astonishingly, already been running in 2,000 family homes. The government’s “children’s secretary” Ed Balls is behind the plan, which is aimed at problem, antisocial families. The idea is that, if a child has a more stable home life, he or she will be less likely to stray into crime and drugs."
