How to reduce Firefox memory consumption

Hate to admit this but sometimes I really suspect the slowness of my browsing experience comes from heavy memory usage by my Firefox, and there is nothing to replace good-o-firefox. I need to open too many tabs and cannot afford buggy Internet Explorer. I’ve tried it and think it helps a lot.

How to reduce memory usage in Mozilla Firefox

  1. Type about:config in the Firefox address bar
  2. Search for browser.sessionhistory.max_entries
  3. Double click on the value 50, change it to something lower, 5 should be good.

Explanations

Averagely we surf less than 5 of the websites we previously surfed before, there is no need to usage up that much memory (which is 50 by default)

    Thanks for the tip. Firefox is buggy & unsecured. I had the update version 2.0 installed but there is this “automatic update” coming in and with a restart it goes back to 1.5.01.0. Any similar experience?

    Hmm, speaking of that I have a bad experience of the Firefox updates. It prompts for update and keep on restarting endless times. I have to uninstall it, remove the firefox.exe and reinstall it back to solve the problem.

    I suspect its one of the plugins I’ve installed that causes this

    I’ve just wrote a few tutorials on Firefox Memory Issues, this seams to be one I have missed! I’ll have to write a tutorial for this to add to my Memory Issues.

    Thanks

    If you type about:mozilla in the address bar you get an excerpt from The Book of Mozilla.

    Great TUT, thanks Hongkiat!

    One thing to keep in mind: The polaroid image itself is a square. So you wanna keep the width and height equal (step 4). Look at W & H in the “Info” tab (FN + F8 for Mac).

    As a gimmick you could add sticky tape or a drawing pin and maybe some dirt or something;)

    @Lenny: You can also right-click the layer and go to Blending Options.

    Cheers
