Firefox and Memory Usage ( Leaks? )
 

Is it me, or does Firefox take up a bit of memory. :P

Firefox takes an average of 101MB with 76.8MB of that being the space for the cache.

I fail to see how you, and others, get such high numbers. Perhaps I'm just cautious, or a neat freak, but I refuse to have as many windows and tabs as I have fingers and toes. (I prefer bookmarks so I can come back.)

I don't have tabs or anything open really, just this website. :/

The others I have are Photoshop, Zend Studio, and SmartFTP

Odd. What's your cache size set to, then?

50MB default.

Wow, that shouldn't make much of a footprint in memory. Got a lot of plugins maybe?

Yes, I was going to ask about plugins. Although I have a fair few and my firefox.exe takes up 80,000K, a quarter of yours!

Firebug, Zend Studio Toolbar, and Talkback

Maybe Zend Studio's plugin has a link to Zend Studio's memory space. Other than that I have no clue. I assume you have the latest version of firefox?

I have it where it automatically installs the updates. I don't know either.

Maybe FireFox's code has gone down the pan.

I have the latest version and I am using 80,000k with two tabs open. That normal and runs fast because I have a 3gigs of memory. I dont know what is taking all that memory up, try reinstalling.

I have a friend whose FF was taking 700MB out of the 2GB available. It's not bad management memory, since it doesn't take up that much usually (tops 100MB).

Try a few things
 

Firebug will by default use up memory to log all network requests (this is already being addressed in Firebug 1.1/1.2). So I'd try browsing with Firebug disabled (disable it from the extensions manager).

Also - try out Firefox 3 Beta 2 (Firebug 1.1b10 works with it) - memory footprint has been a big focus for this release.

Apparently everything gets worse in FireFox 3 ;)
