I've been on FF since shortly after it became available. I had more problems with 4 than most seem to have had, but few since. FF 6 ran fine, and I was surprised to see 7 come along so soon. But I have had *no* problems with 7, nor 7.1 that didn't turn out to be a website issue. CPU doesn't warm up, memory stays around 40% with T-bird running and God knows how many tabs, I never counted. I short it has been trouble-free.
What am I doing right (for a change)?

POSTSCRIPT: I've had far more strange problem with TR lately, though, like having to log in every time I hit "reply"-?!?!.
