Firefox is a resource hog....

[Randy Cole]

When I have a number of tabs open, firefox runs slowly & uses lots of
memory.  And when you close tabs, it doesn't seem to release the
memory.  What can I do about this?

Hi Randy, other things you could try if you haven't yet:

   #1 - using htop, top, or ps make sure all firefox processes
        are dead.

   #2 - upgrade to a later version?

Consider installing the Flashblock and NoScript add-ons.  Most
resource issues I've experienced with Firefox are not due to Firefox
itself but to all of the flash and javascript that many sites are
using these days...

One thing I just ran into: Ubuntu's Firefox-3.0.10 packages (the
latest version, AFAICT) are MUCH worse than the latest upstream code.
At work I deal with a web ap with a UI that's javascript-heavy, and it
brings my browser (and my machine, for that matter) to its knees after
about an hour.  It leaks memory like old car A/C units leak freon.  I
can actually watch it leak memory by running top.  I downloaded the
3.0.11 release directly from Mozilla and installed that side-by-side,
and the memory usage is extremely stable, at least in the short term.

Note of course that you can simply remove flash and turn off
Javascript if you don't need those; but unfortunately these days it's
getting harder and harder to get by without them (especially
Javascript).  If you need them (e.g. you need to use problematic
sites), you're kinda stuck.  And FWIW many of the Javascript problems
are caused by bugs in Firefox.

This is why I use the aforementioned add-ons.  I want the flash plugin
installed and js enabled, but I don't want flash or js to run unless I
explicitly allow it to run on a site-by-site basis (that is, if my
interaction with the website requires it).  There are many sites that
will peg your CPU due to all of the flash/js crap that is running
(mostly for ads and whatnot), and all this is usually not required for
interaction with the site.

Agreed, there have been several cases of this as well...

I guess what I'm saying is it doesn't always help.  In my case, the
only sites I care about that make substantial use of either one would
be completely non-functional without them (e.g. Youtube and some
internal web apps at work). It's the very thing I need that causes the
problem...  :(
