Firefox is being a memory hog - how to fix this?

Hello,

I believe this is the correct forum for this type of post.

With a few tabs open, my Firefox is eating over 450MB RAM. And, if I open more tabs, it quickly grows to 600+ MB.

This cannot go on. How can I make FF eat less RAM? I tried recompiling it with xulrunner-optimized from AUR, but it didn't help at all.

I have the extensions: 1-ClickWeather, Adblock Plus, DownThemAll, NoScript, StumbleUpon, Tab Mix Plus. I'm using 64-bit Arch.

Any suggestions?

Thanks.

Try disabling Tab Mix Plus.  I recall that add-on having issues with memory leaks.

Are you sure it is 600mb? The real usage is the RSS column when you do 'ps uxw'.

I found that Adblock Plus is pretty resource intensive. I replaced it  with a custom /etc/hosts,  and a userContent.css file in my firefox profile. iIt blocks about 80% of what Adblock Plus does while lowering memory usage.

If you're wanting light-weight ad-blocking, use Privoxy.  It uses next to no memory, and does not balloon in memory usage due to use.

Yes, pretty sure of that. Will try the /etc/hosts solution.

Be sure to use the latest Flash plugin.. I know older versions caused all kinds of problems.
