Apply These Solutions To Resolve Firefox High Memory Usage Issue

To eradicate Firefox using too much memory problem, check out these following fixes.

Solution 1: Reduce The Pages Stored In Browser History Session

The value of browser.sessionhistory.max_entries helps to determine the maximum count of pages in Firefox browsing history. This value is set to 50 by default. So, if you don’t want to visit more than 5-10 previously browsed pages, set this value to 5 or 10 based on your requirement. To apply this method, go to ‘Firefox search bar and enter ‘about:config’ in the box. Find the browser.sessionhistory.max_entries and then double-click on its ‘Value’. Now, change this default value to something lower (5-10 recommended) and Restart the browser.

In case, you are using Firefox version 1.5 and above, locate browser.sessionhistory.max_total_viewers. It displays the number of cache content viewers in terms of ‘bfcache’. So, if you find the default value is set as -1, then change it to 0. Hence, it will make sure that no browser pages are stored in the device memory.

Solution 2: Limit Cache Disk Capacity Or Disable It Entirely

In Firefox, whenever you load new pages, it automatically adds them to the cache for avoiding reload and redisplay of websites. If you open about:config, the default value for browser.cache.memory.capacity is -1. To fix the cache limit in Firefox, click Options and then on ‘Advanced’. Then select Network/Cache to access browser.cache.disk.capacity. In order to limit this cache value, make sure that the browser.cache.disk.enable is kept true.

This solution will work if you set browser.cache.memory.enable true as well. Also, set the number of KB used for memory cache and disk cache as 1 MB (1024 KB) or as per your requirement. You can also choose to disable the option to add cache totally. So, put the values for browser.cache.disk.capacity and browser.cache.memory.capacity as 0.

Solution 3: Use Less Tabs, Lower Extension And Themes Usage On Firefox

If opening multiple tabs on Firefox is causing memory leakage, keep this number low. Also, you can experience RAM issue due to too many themes and extensions, hence disable a few to make more space. To identify the memory usage corresponding to each of these extensions, open the browser in Safe Mode. This will allow you to compare the CPU usage and storage consumption on your PC due to these Firefox Adds-ons and components. So, you can determine the extensions that are causing this memory shortage and disable them manually.

Solution 4: Turn On Flash Hardware Acceleration

In case you are getting this Firefox error due to hardware and graphics card overuse, you must ensure whether ‘Enable hardware acceleration’ option is checked. If you turn on this feature, it will reduce the memory consumption towards graphics content on Firefox.
