Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O 10.4; en-US; rv:1.9b1) Gecko/2007110903 Firefox/3.0b1

Mac OSX 10.4.11, Firefox 3.0b1, brand new clean profile.

I was trying to track down a render bug while I noticed that my system was slowing down. Looking at the Activity Monitor I noticed that Firefox was using 800Mb+ of RAM, raising fast.
Forced down.

Reopened it, reloaded the HTML file but after a few refreshes it started again and I've seen going it up by 10-20mb each second.

I didn't have any tool to track it down, so I've fired "Sample" from Activity Monitor, recording 3 samples.
I even tried to make Fx crash in order to get a report, but nothing.

I know that this isn't much useful, but I lost the last 2 hours trying to reproduce this reliably, but nothing. Feel free to close it if the samples aren't enough to do anything.

I'm using Portable Firefox CX for OSX to launch a clean profile. I don't know it this could be useful, but I'm trying to cover everything.

Reproducible: Sometimes

Steps to Reproduce:
I can't reproduce it reliably. :(

Actual Results:  
Skyrocketing RAM usage. Up 10-20mb each second.

Expected Results:  
Stable RAM usage at idle. :P

That was on this site: I think ?
I noticed that madness as well, when viewing it with Fx b1 to analyse bug 404660.
Minefield latest nightly and my Camino trunk build didn't have any problem.

Hi Philippe. :P
Yes, that was what I was working on when I noticed this issue.
I'm glad that it's fixed in some ways on the latest nightly. :)

I don't know for sure if it is fixed or not. The latest nightly I have (20071120) is stable on that site (both with the same profile as I used for FX b1, and with my usual profile for nighty builds).

Note similar issues in bug 403481.
