Hi, this morning i opened
http://bugzilla.gnome.org/buglist.cgi?product=evolution. This page is huge and
took some time and a lot of memory too load, that's OK. Then i closed its tab. I
kept browsing for 30minutes (on various websites) but mozilla never returned
memory to the system.

7745 benoit    15   0  418m 250m  16m S  0.0 49.8   5:09.97 firefox-bin

Number of entries: 	540
Maximum storage size: 	21504 KiB
Storage in use: 	20843 KiB
Inactive storage: 	15476 KiB

Moreover, firefox memory pages were not swapped, so my system was lacking free
memory. I had to restart firefox to get my memory back.

May be firefox is not able to return memory to the system, but i would have
expect unused memory to be swapped...

Before restarting firefox, i re-opened the huge webpage.

Then i closed the tab, opened a new tab, browsed a few pages (for 5 minutes).

Again, i re-opened the huge webpage and closed it

thanks.

Please recheck with a current nightly a lot of work has been done on Firefox's
memory usage bug 131456 was one of the bigger fixes.

I have checked this bug with the 2005_08_05 nightly build for linux and the bug
is still consistently reproducible.

still here with

Mozilla/5.0 (X11; U; Linux ppc; fr; rv:1.7.10) Gecko/20050824 Firefox/1.0.6
(Debian package 1.0.6-3)

same memory usage 370MB. Memory usage never goes down, even after 30min

Are you still seeing this using the latest trunk build?

This is almost certainly a dupe of some existing bugs which talk about large tables and how we don't work well with them. A lot of this is improved in the trunk builds. I'm going to close this bug as INVALID, since it doesn't provide important information about the leak, but it could just as easily be closed as a duplicate of another bug, so note that this is on the radar and is already vastly improved.

I am tired of the 'try the latest trunk it's better'.
First of all, there are no trunk build for ppc. And bugs don't get resolved without work. I can definitely reproduce it with Iceweasel 2.0.0.3 (rv 1.8.1.3). I don't get what i could do to best explain this bug : I gave an URL and it is reproducible.
