5 Ways to Reduce Firefox Memory Usage/Leakage

Do you suffer from Firefox memory leak? Check this tutorial about some tips to reduce Firefox memory usage on Windows, Linux and Mac.

Firefox is one of the most popular browsers in the world and one of those who managed to compete with Internet Explorer seriously. Now it seems that it is losing some bellows and the user number is shrinking little by little.

This is not because the browser has suddenly become bad, but because of two fundamental issues. One is the fact that other browsers, such as Chrome are making a dent. The second is that Mozilla, where they develop Firefox, turn a deaf ear to the complaints of users who claim that the browser consumes too many resources of a computer.

This has led to the fact that several different versions have been released in recent years without any of them having radically blocked the excessive memory consumption of Firefox.

So, at this point, if you want to reduce Firefox memory usage on your computer and, rebound, run faster, you’ll have to get it for yourself by following some tips:

Increase Page Speed Load

  1. Open Firefox and in the address bar type about:config and press Enter.
  2. You’ll see a Firefox security warning telling you that you’re about to play with dangerous things. Continue if you feel brave.
  3. In the search box that appears above, type network.http
  4. Locate the entry network.http.pipelining and change its value to true by double-clicking on the line.
  5. Locate the entry network.http.proxy.pipelining and change its value to true.
  6. Locate the entry network.http.pipelining.maxrequests and change the numeric value to 10.

With this, what you are doing are two things: enabling pipelining, which allows the browser to make more than one request to a web page at the same time (by default only one is made); and setting the value to 10 the browser will make ten requests at the same time. You can change the value to less or more to test how it works better.

Reduce Firefox Memory Usage for Cache

To access data quickly, browsers store all kinds of information in cache, and although it is beneficial because it allows you to load pages that you visit a lot more often, sometimes this is inefficient when you open many websites, you close and still Firefox is using a lot of memory to keep them in cache.

To reduce the amount of RAM the browser uses for its cache function, do the following:

  1. Type again in the address bar about:config and press Enter.
  2. In the search, type browser.sessionhistory.max_total_viewer.
  3. Change its value to 0 by double-clicking on the line and entering the new amount.

Reduce Firefox RAM Usage Minimized

The chances are that if you have the browser minimized is because you’re not using it. However, that does not stop you from continuing to consume memory for each open tab with extensions. With this trick, you can create a variable in the configuration that will reduce the memory consumption of Firefox when it is minimized.

  1. Type about:config in the address bar.
  2. Right-click anywhere and select New > Boolean
  3. In the drawer that appears type config.trim_on_minimize and press Enter.
  4. Select True as a value, press Enter and restart Firefox.

If you want to return to the default values, you have to follow the same steps and revert the changes. Which will be easy since Firefox highlights which variables have been modified by the user.

Other Ways to Reduce Firefox Memory Usage

Don’t add unnecessary add-ons in Firefox

If Firefox already consumes enough memory, this consumption can be triggered if you also use a good number of add-ons or extensions. There are some of these extensions that only in themselves already consume more than they should. The idea is to get rid of the add-ons that you do not need.

Keep in mind another point, and there are some of these extensions for Firefox that analyze the content of each page you open to performing the odd function. This causes the load of one or several pages to be ballasted.

Install add-ons that consume little memory

Since you will continue to use add-ons, at least use those that consume less memory. If you look a bit, you will see that there are several add-ons to perform the same functions, only that some are more optimized than others. Test with several until you find those that make your Firefox work more fluid.

Don’t use themes for Firefox

The themes for Firefox are usually beautiful backgrounds but present a couple of drawbacks. The first one is that they require that the image itself or texture be in memory, so one way to release some RAM is to remove themes or ‘people’ for Firefox.

Group Tabs in the browser

One of the novelties of the latest versions of Firefox is the ability of the browser to group the different tabs open in groups of tabs. Organizing the tabs according to categories is an excellent way to reduce some memory consumption.

Restart Firefox

When you have been browsing for a long time and have opened a good number of pages you can always keep track of junk traces of pages that you do not even have open, there are also those who do not turn off their computer in several days and leave the browser open.

Restarting the browser by closing it and reopening it every so often is an excellent method to clean RAM a bit.
