Stop Firefox munching memory - HOW!?!

Dear Anyone.

So I start off with 12gigs RAM. Open Firefox. Use it a few hours (I dunno, some serious stuff like learning programming, some fun stuff like stoopid games!) Then I hear massive hard-drive activity, look in Resources and I’m down to 700K of RAM. Closedown Firefox, reopen it, restore all tabs/pages (so same games, same E_mail, same everything) and I got 8GIGS of RAM free, doing the same things.

So it’s Firefox munching memory, not clearing the memory it’s munched, going onto the next cleared chunk till there’s nothing left. And it’s ALWAYS been like this. Every version does this.

I love Firefox - apart from this bug that’s been there from day 1. Please - anyone know how to stop it memory-munching? Many times I’ve had other software crash because Firefox has munched all the memory. I don’t wanna stop using it - but there’s gotta be a way around this by now, no?

Yours hopefully

Chris.

The first thing to try is Troubleshooting Mode. If Firefox behaves better in Troubleshooting Mode then the problem is likely with an add-on you are using.
