Memory usage in Firefox 3.1 Beta 3

Hi all,

A few days ago, I have reviewed Firefox 3.1 Beta 3. It's quite lovely. It boasts improved Javascript performance, it comes with new usability and privacy features, it supports future HTML multimedia elements ... But nowhere in that article did I mention the memory usage.

I did this for a good reason, because measuring memory usage accurately is not a simple thing. It depends on many things and what you see is not always what you get.

So today, you have two things:

1) Review of memory usage, Firefox 3.1 Beta versus current release.
2) Tutorial on memory management, including advanced stuff on Linux, like memory maps under /proc, working with ps utility, memhog, and other cool stuff.

Worry not! Windows memory management is also addressed.

Enjoy:

Spoiler: it looks good, overall there seems to be an improvement. But read for the full thingie.

Comments and suggestions are welcome.

Cheers,
