View Full Version : firefox Memory usage problem

16-01-2007, 01:41 PM
Hi all

I am a long time firefox user but I have been having problems with memory usage, earlier today i had 2 tabs open (pressf1 pages) and firefox was using about 260000 kb of ram, and this happens quite regularly

I love firefox and its extensions but this is tipping me towards opera in a big way

Is there a way to cut down the memory usage or is this something I will have to live with

Might be the add ons too if u have any.

I've got 2 tabs open and using 3 add ons and using 40,092k!

I just disabled the add ons tho, made no diff.

I just found a list of memory probs


apparently ie tab can cause a memory leak, although I can't figure out if this occurs when the page is being viewed in IE tab or what, as i havent used IE tab today but it is installed


Hmmmmmmm lots of reading to do

There maybe a flaw in FF2 too, to do with passwords.

According to the latest Netguide, be careful what site/s you go to as if the pw saving is on automatic, it'll put your password/username in automatically on a fake online login form.

Workaround is to disable FF's autosave function under tools/options.

It doesn't say if this affects FF2 or 2.0.01 or both. BUT it also says MS nor Mozilla have released a patch for this flaw.

IE 7 is also affected it says, but FF is more vulnerable to this RCSR (reverse cross-site request) flaw.

The "RCSR" issue is simply a particularly nasty way of exploiting XSS vulnerabilities in web sites. It can also be used if you control a transparent proxy en route to the server, in which case you could get the username and password if the user signed in anyway. The take home message from this is to use passwords which are shared between sites to a degree appropriate for the security required. Don't share a password between Myspace and Trademe, or between your blog and your online banking.

I sort my various accounts into "security levels". These run from trivial passwords such as my computer login, which could be bypassed anyway, through to unique passwords for financial use. All my passwords are equally strong but services with lower security needs share a password with a greater number of different services.
