Firefox is one of the most popular browsers today, but even this stable, user-friendly browser could cause some problems. After some time of using, Firefox could start to take more memory than it should, but we’ll tell you how to solve this problem.

First, make sure that your Firefox is up-to-date, because newer versions of the browser usually take less memory. You can also disable or delete some unnecessary plugins and add-ons, because they also could use a lot of memory. Actually, disabling unnecessary add-ons and plugins proved to be the best memory saver. Of course, if it turns out that you need some of the disabled add-ons, you can always re-enable it.

But if your browser is updated, and you run only necessary plugins and add-ons, you’ll have to do a couple of tweaks in order to solve the memory leak problem. Here’s what you should do:

  1. Type about:config in Mozilla Firefox bar and adjust the following preferences (by double-clicking on them) to enhance your memory:
    • browser.cache.memory.capacity (set to 0)
    • browser.cache.memory.enable (set to false)
    • browser.sessionhistory.max_total_viewers (set to 0)

    • browser.tabs.animate (disable)
    • browser.sessionstore.max_concurrent_tabs (set to 0)
  2. Now, edit the following preferences to boost the loading speed:
    • javascript.options.jit.chrome (set to true)
    • javascript.options.jit.content (set to true)
    • content.notify.backoffcount (set to 5)
    • network.dns.disableIPv6 (set to true)
    • network.http.pipelining (set to true)
    • network.http.proxy.pipelining (set to true)
    • network.http.pipelining.maxrequests (set to 8)
    • plugin.expose_full_path  (set to true)
    • ui.submenuDelay  (set to 0)

You also should know that the more powerful computer you have, the more memory Firefox will use. So you shouldn’t think that you’ll surely avoid memory leaking problems with Firefox if you have more memory in your computer.
