Hi, I have Firefox 3.5 (latest one) on Vista sp2.

My question is what is the typical RAM that peoples will use?

When I first start it, it will be around 30-40mb, then will gradually rise up. With 3 tabs open and after being opened for roughly 25 minutes it's at 340mb RAM usage. If I close the tabs it stays the same, but restarting it will lower it for a while. If left to idle it will slowly build it self up to around 100-150mb. It has at times gone up to 900mb to 1gb of RAM, and this really bogs the system down and is nothing like it should be doing IMO.

In terms of add-ins I have Skype, McAfee Site Advisor, .net framework and Realplayer, and I am quite sure it's none of these causing it.

A google search didn't help much, so thought I would try picking your collective brains.

TIA, Joe

I'm running around 300mb of memory to run FF3.5 with about 50 tabs open.

What OS and AV?

Try using JavaRa and also disable or remove any add-ons you aren't using and see if it reduces.

OS - vista sp2(:()

AV (anti-virus?) Mc.Afee, and some anti spy/adware stuff.

Done that as well, will see if it makes a difference.

Most likely to be an addon causing the problem.

Personally I'm a bit sceptical about the FF features "Block reported attack sites" and "Block reported web forgeries" (Preferences - Security). If enabled they create huge data files in your profile folder and it seems as if FF checks every new site towards these files which of course consumes RAM (at least I guess it does)..

I've disabled them both, but then I only visit friendly sites like this one (and my Linux OS is less vulnerable than win).

How much ram is it using with those disabled?

70M or so with nothing but Brisky opened, but that's running Linux :P so might not be the same under Windows

Cheers for all the help. I disabled all the add-ons and it's now only a couple of hundred mb at the most, so a lot lower.

Thanks,

Joe
