I came in to work this morning and FireFox was using 2GB of memory.  It had
crashed and was displaying a "Firefox has encountered an error and needs
to close" dialog.  It was working fine when I left work last night.
I had about 30 tabs open probably (which is about 10 more than normal -- see
the actual list below).

I'm appending some data I collected last week.
...............


I have Firefox 3.0.2
 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.2)
 Gecko/2008090514 Firefox/3.0.2

It typically gobbles up memory so fast, it reaches 1.8 GB routinely,
and I have to restart it.

                               Virtual Size:    Private Bytes:

Initial (Wednesday)      :     ~  180,000 K     ~   104,000 K
(I didn't write them down, but I remember the Private one was 104)

After running
overnight Wed
(Thursday, 10:25 AM)     :      1,124,248 K       1,024,728 K

After restart
(Thursday, 10:30 AM)     :        178,912 K         106,732 K

Didn't do anything except
let FF3 sit there minimized since
restart, until afternoon
(Thursday, 3:52 PM)      :        387,808 K         317,300 K

FireFox3 seems to be consuming memory at the rate of about 50 K / second !
I can watch it count up in the Process Explorer window;
it's like a digital stopwatch counting upwards.  In the time it's taken me
to type this last sentence or two, the numbers are now:
                                  388,832 K         322,852 K

After running overnight
(Friday, 9:10 AM):              1,042,536 K         945,556 K

4. Wait

See the initial description.  Typically I see 20K/sec to 50K/sec gobbled up.

Right now, I must restart Firefox3 every morning, and reload my tabs.  This is bogus.

Comment 2

[Jesper Hansen]

Could you try and disable one addon at a time or try safemode to see if its one of the site scripts that goes bogus?

Comment 3

[Mardeg]

A couple of extensions have emerged to help diagnose memory usage:
https://addons.mozilla.org/en-US/firefox/addon/7055 and
https://addons.mozilla.org/en-US/firefox/addon/2490

I hope installing them doesn't make the problem automatically disappeat, and they are found useful in some way.

Attachment: Started FF3.02 Friday afternoon; no addons enabled; 26 tabs; Monday morning, 2GB mem in use, and it crashed

I restarted FF 3.02 Friday afternoon; with no addons enabled.  I left it sitting with 26 tabs Friday evening; came back in to work Monday morning, and it had crashed with 2GB memory in use.  So I don't think the memory leak is with the addons.  Please fix this.  I'll be glad to load a debug whatever if someone sends it to me.  I have MSVC++ 2008 loaded, if that helps.

Comment 5

[Jesper Hansen]

Please try these things so we can narrow the possible bug down
Test one:
Create a new profile. Help on the subject is here http://support.mozilla.com/da/kb/Managing+profiles and here http://kb.mozillazine.org/Profile_Manager - rerun the tabs.

Test two: 
When the above has crashed then test with the new profile without Java and Flash.

Test Three: 
If test two crashes it as well, disable javascript in the new profile along with the plugins in test two. See about:config => javascript.enabled

Comment 7

[jeffrey.johnson]

I must restart firefox every morning, because when I leave it running overnight with about 20 tabs open, but with the application minimized, it'll be using 1.5GB or more (or have already crashed) when I come in.  

Here are 3 external pages currently discussing this same issue.  I'm not the only one having this problem:

i will check this memory leak report

Comment 9

[jeffrey.johnson]

I downloaded and installed a Windows XP update that fixes a GDI memory leak:

http://www.microsoft.com/downloads/details.aspx?FamilyID=9b5edfc8-a4bb-4080-9063-6518166e2dab&displayLang=en

and after that, FF3 memory has been very stable. I’ve been running this about 3 or 4 days now, and FF3 memory use is OK. So maybe that will fix the problem. I would like to hear feedback from others.

Comment 10

[jeffrey.johnson]

I think this problem is the same as bug 464648.

Comment 11

[Carsten Book [:Tomcat]]

so far i was not able to reproduce this Memory Leak.
Do you see this memory Leak also with a new Profile ?

Comment 12

[ann_thrope]

I see a similar problem here. Starting with a new profile without add-ons, as soon as I open an MSDN page, memory increases constantly. Interestingly, the OP's list of open tabs also conatins an MSDN page.
