Does anyone else have a problem with FF slowly consuming more and more RAM?

I just had to restart it because it was using over 1GB of RAM.

I closed it and the usage dropped by about 1.3GB of RAM and my computer sped up.

This is a brand new core i5 computer so not a slow coach and was acting really unresponsively with FF open.

in the address bar place
about:config
press enter

right click (within this window) then add integer then use this
browser.cache.memory.capacity
set the value to -1

this will set the browser to use a percentage of memory (ram) instead of trying to use the max amount

close the browser down and then restart the browser ...

Cool I've set this now.

Will keep an eye on it.

Thanks

The leak came with version 4.0, it was supposed to have been fixed with 7, but I'm still having some problems, although better than 6.

Steve Gibson, on Security Now, has said that it was so bad on his machine (Windows XP), that it was using over 1.2GB of memory after the machine slept over night. Closing the open tabs would reduce it to 800MB. Quitting and restarting dropped it to around 200MB. He went back through the previous versions and is currently on 3.6.n, which is the oldest supported version and this doesn't have such a big memory leak problem.

My laptop has been up for several days and FF has been running since the new start. It has had several hundred open tabs and Flash objects. It is currently using 218MB. It looks like they have finally solved the problem - the previous version would be up over 1GB used memory by now.

FF7 has been a bit of a PITA of late, hogging loads of memory and crashing.

So, I've uninstalled it and decided to do a fresh install.

I can't connect to Mozilla though, is the site down? - can one of you nice people try?

Cheers

Dave

3 days and a couple of hundred tabs later... And it is using 193MB on my machine, about 50MB less than Firefox 7 after a week.
