Reducing your memory usage in Firefox

ADVERTISEMENTS

Ryan on CyberNet news has a good post on reducing your memory usage in Firefox that explains which extensions have memory leaks and which will slow down Firefox’s performance.

Let me list a few of the extensions that cause these problems.

  • IE Tab (memory leak)
  • Session Saver (memory leak)
  • ForecastFox (memory leak)
  • Filterset.G Updater AND FlashGot used in conjunction will produce a memory leak
  • FasterFox doesn’t have a memory leak specifically, but it will not help your Firefox performance.
  • Tabbrowser (slows Firefox)
  • FoxyTunes (memory leak)

Are you using any of these extensions?

    Hey John, well FoxyTunes lets you play your media from firefox with the most popular players WMP, Real Winamp etc.

    Well that’s great but whenever i used to open WMP from outside Foxy or from within Foxy, i used to get good music, here’s what bugged me.

    Try using Foxy for this, open any player you want to listen the music in and then close the player by clicking the close button in that app, now press ctrl alt del and see that your CPU usage starts going up to 100% frequently, if you would like to see a detailed process tree please use Process Explorer which shows you which the entire tree where the process runs at.

    Foxytunes should be added to the list as well, I agree with Keith!

    I did see this @ Digg. Nice post, I guess extensions make all the difference.

    - it sounds that your problem with FoxyTunes might have something to do with your local installation of WMP. In any case, the symptoms you describe don’t sound like a memory leak at all. Could you please drop us a note with a few details here, so we can investigate what you’re seeing?

    - great post, thanks! A quick question - were you able to reproduce the problem with FoxyTunes that Keith was seeing before adding FoxyTunes to the list? Did you see a memory leak? It sounds like a local problem that only a very small percentage of users might be seeing…

    We are committed to solving each and every reported problem, and appreciate the feedback and your help in identifying and solving such problems - thanks! :)
