Some About:Config tweaks for memory usage in FF.

[link|http://techpatterns.com/forums/about623.html|TechPatterns] has some tips and a link to a Mozillazine thread about it.

I suspect in my case it's related to at least a few things:

I have Session Manager and Crash Recovery in TabMixPlus enabled. They have to know what to restore after shutdown, so they must keep a current picture of the current tabs somewhere. Since many of my tabs auto-refresh whether I want them to or not (various newspapers, etc.), it seems reasonable that that's a big part of the increasing memory usage. (I would think the code would be smart enough to overwrite the previous tab cache though.)

I'm a big fan of TMP, SM and CR so I don't know if I'm willing to make the trade-off of turning off those features for a smaller footprint.

I'll have to check my settings for A:C and see if that makes a difference as well.

In short, FF may be working as designed when my combination of extensions and settings are used. :-/

HTH.

Cheers,
Scott.

Don't see much of a memory problem on OS/2, but.....

... what I have seen the most of is increasing CPU usage if I leave it running all the time. This usually happens after I start get moments of CPU hogging, bogging the entire system down at times.

When I first start FF, CPU usage is typically about 10%. After several hours of leaving it running, I will start to see CPU usage creep up until it gets to as high as 75%. That's when the entire system becomes sluggish, with momentary spikes of 100% CPU usage. #7 on that list of hints given in the quoted section ("Once in a while, close the browser completely and re-open it."), is usually the cure for this.
