One thing I just ran into: Ubuntu's Firefox-3.0.10 packages (the latest version, AFAICT) are MUCH worse than the latest upstream code. At work I deal with a web ap with a UI that's javascript-heavy, and it brings my browser (and my machine, for that matter) to its knees after about an hour. It leaks memory like old car A/C units leak freon. I can actually watch it leak memory by running top. I downloaded the 3.0.11 release directly from Mozilla and installed that side-by-side, and the memory usage is extremely stable, at least in the short term. > Consider installing the Flashblock and NoScript add-ons.

Note of course that you can simply remove flash and turn off Javascript if you don't need those; but unfortunately these days it's getting harder and harder to get by without them (especially Javascript). If you need them (e.g. you need to use problematic sites), you're kinda stuck. And FWIW many of the Javascript problems are caused by bugs in Firefox. --=20 Derek D.
