FireFox is leaking

[MtK]

Hi,

I think I have a few program that leak memory constantly.

I've noticed a huge increment in the amount of memory FireFox 2.0.0.3 & IntelliJ 7M1a use (above 100MB of RAM)...

Is there any way to check that?

Process Explorer would be a good place to start,

check out the tools here for more options

Obviously I user Process Explorer to notice the problem.

which tool should help me pin-point the problem?

If you look at the process object in perfmon for the firefox application, what do the "virtual bytes", "private bytes", and "working set" counters show as values when the "leak" gets bad?

I doubt it's Firefox. I am using Opera right now, and with only 4 tabs I am at 188 megs in Mem Usage already.

It's firefox starting from version 1.5 It sucks up the memory, it's horrible, just a few tabs and it eats up more then 100 megabytes of ram. **** it. You either use versions below 1.5 or you give up the whole thing.

last night I stated in another forum about this problem where FF reached 300mb+

Working set, virtual bytes, or private bytes?

4 months & 4 new version, since tI first posted this topic - FireFox 2.0.0.7 is still leaking (& badly)...

it starts with about 37mb (Private Working Set),

but quickly rises to over 250mb.

This is an old subject that's been brought up on virtually every tech site and every tech forum. Firefox isn't leaking, it aggressively caches EVERY page you ever view. If the memory isn't available, it simply won't use it, but I do admit Firefox doesn't give back memory after it takes it, and I often kill the process once a day and restart Firefox (so it re-opens all my tabs).

There is a setting in FF where you can set a limit to it's caching, but it doesn't work for me:

# Access the "about:config" url by typing that in

# Find the browser.cache.memory.capacity key.

# Double-click it to change the value

# Adjust the value. For those with 512MB to 1GB of RAM, start with a value of 15000. For those with less (between 128MB to 512MB), try a value of 5000

As much as I like caching & speeding up the browsing process, FF is never faster & it get stuck every few minutes...

That normal, FireFox cache lot to system resources, have to remember that not truely using 100mb of ram that page cache too, mine at 230mb of system resources. It lot less on other OS

Hmm I would say just get more ram or faster box, I mean Sunfire V480 with 8gb of ram, dual sprac3 1ghz, two 72gb 10,000RPM HD run FF just fine
