Description

7 years ago
I am using Firefox 12, currently beta. Mozilla/5.0 (X11; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0.

I recently visited a web page that caused Firefox to use enormous amounts of RAM. It would very quickly fill my system's memory and start swapping aggressively, far beyond what is normally used by Firefox. My system has 2GB of RAM, and Firefox usually only uses a few hundred MB of RAM.

This is the site:

http://ska.ac.za/

It is reproducable, even without addons, but not in a clean profile.

Today I experienced the same with another site:
http://cookit.e2bn.org/

The same effect is reproducable here, even without addons, but not in a clean profile. I haven't experienced this on any other sites, even though I use this system most of the day.

I have loads of modified preferences. I can paste it here if it will be helpful.

yes, all of about:support would be useful, along with about:memory?verbose

Comment 2

I can't reach about:memory while the problem is present (the browser and the whole machine is basically unusable due to massive amounts of IO due to swapping). When I finally manage to close the tab, the memory is freed immediately and returned to the OS.

Here is about:support. It is in Afrikaans, so feel free to ask if that confuses things and I can translate anything.

The best way to figure this out is for you to find the way to reproduce this problem. Some things you could check:
- does this occur on other Firefox versions (like release (11)/nightly)?
- it might be useful to check a en-US build to see if it has the same problem
- try copying stuff from the problematic profile to a new profile to see if you can find the specific list of things that cause the problem (e.g. prefs.js, userContent/userChrome.css)

Friedel, does this reproduce with nightly build and clean profile?

I am unable to reproduce with Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:15.0) Gecko/15.0 Firefox/15.0a1. memory use is nominal

It didn't happen with a clean profile even on the Beta version I had then (12). I recently experienced this on another site with Beta 13. If I can find extra time I'll try to play around with Reset Firefox or similar.

I just used Reset Firefox, and the problem is gone. I experienced this recently on more and more sites, but luckily this is gone. I hope it doesn't affect too many users. Should we close this bug? I guess there is not enough useful information.
Yeah, right now the bug is not actionable, and there's no way to tell what percentage of users the underlying issue affects...

So unless you have a backup of your profile (that reproduces the issue) and have time (or can find someone else) to do what I suggested in the third bullet of comment 3, the bug should be closed.

Please reopen if you figure out the problematic setting.
