I use Mozilla Firefox as my primary web browser, it's excellent in almost every aspect except, it consumes too much ram.

Sometimes/most it eats up to 200-300 MB and it's not acceptable, will Firefox receive an update which will stop from eating so much ram?

I've looked for the tweaking to do in "about:config" it hasn't lower it down than the normal and also "Firefox Optimizer" it tells the user that it's consuming 400kb's but it's not true, only hiding the real facts.

As a everyday user of Firefox browser, I really want my number one browser to not be slow nor eat my ram!

This happened

Every time Firefox opened

== Since I started using version 3, as I can remember.

I have noticed that that internet explorer 7, and iTunes suffer from the same problem, and each update consumes more memory!

If you think 200-300MB is a lot, you don't have enough RAM to begin with.

The current work examining memory usage is covered at http://blog.vlad1.com/2010/05/10/losing-my-memory/

Ugg, many months later and it still eats up memory on my Netbook computer like nobody's business. I am seriously considering switching to Chrome after having been loyal to Netscape/Mozilla/Firefox for a very long time.

Plugins and faulty extensions may be the real culprit. Try browsing in Safe mode or with just Flash plugin enabled and report back to us.

Even in safe mode, Firefox 4 takes over 1500 megs of virtual memory and 800 megs shared. This is on a laptop with 2G ram, so it's almost half of actually consumed memory. I have a lot of tabs hidden behind Panorama, but those are not in active use so I'd prefer them not to be loaded at all at startup, only when I try to access them.
