Firefox - Huge Memory Hog 4

Posted by JD 03/04/2011 at 12:00

I use Firefox with just a few extensions. Seven (7) are enabled right now. I have 3 tabs open, including the window I’m typing this article into.

So, why is Firefox using almost 1GB of RAM on my system?

  PID USER          PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND           
30488 userid        20   0  973m 673m  26m S    9 33.5 445:22.42 firefox-bin

Seriously, I’d like to know. What could Firefox v3.6.13 be doing that needs more than 100MB of RAM? I see this happening almost every week.

What sort of memory use do you see with Firefox?

    So I shutdown Firefox and restarted it with the same 3 tabs open.


    
  PID USER     PR  NI  VIRT  RES  SHR  S %CPU %MEM    TIME+  COMMAND           
    
14706 userid      20   0  314m 119m  26m S    2  5.9   0:10.51 firefox-bin

    Can someone at Mozilla please run Purify and fix the memory leaks? Memory leaks are bugs too, BTW.

    I bought a new machine with additional RAM, ever since I upgraded to Firefox 4, this machine runs just like my old one – memory too high, swapping very active, things slow.

    Your numbers to not impress me.
    I just noticed that FireFox 4 had gobbled up 1.5 gigabytes of my memory…
    Restarted it with the same frames, and it started at 0.5 gigabytes.

    Yes, I’m running with 10+ tabs open, but seriously…

    And this is without counting the plugin container.

    Firefox 6.0.2 still has this memory hog issue.
    Can someone at Mozilla please, please, please run Purify? Please?
