What Causes Firefox to Use a lot of Memory?

We investigated the matter once we received several reports from a lot of users and came up with a set of solutions that had solved the issue for a number of users. Also, we looked into the cause of the problem and devised a list of potential culprits due to which the problem might be triggered. Now that you have a basic understanding of the nature of the problem we will move on towards the solutions. It is recommended that you implement these in the specific order that they are provided in.

Solution 1: Restarting the Application

If you have been using the browser for extended periods of time and a couple of tabs have been open for a while, it can increase the usage of memory. Therefore, it is recommended to completely refresh the application by restarting it. This helps reinitialize the browser and helps in decreasing memory usage.

If you have installed any extensions or custom themes on the browser it is possible that they might be using more memory due to certain modifications that come with them. Therefore, in this step, we are going to disable all the extensions and themes. For that:

Solution 3: Enabling Hardware Acceleration

Flash content requires a memory draw in order to load. However, the hardware Acceleration feature inside the Firefox browser can reduce the stress on your Memory if a dedicated graphics card is installed on your system. Therefore, in this step, we are going to be making sure that the Hardware Acceleration feature is enabled. For that: Note: Only enable this option if you have a dedicated graphics card installed on your computer because this option enables the use of the dedicated graphics card to load flash content instead of the processor and memory.

Solution 4: Updating the Application

It is possible that the version of the Firefox browser that you are using is old. In each update to the browser, the company provides important improvements and bug fixes which ensure a smoother experience for the user. Therefore, in this step, we are going to be checking for updates to the browser and installing them if available. For that:
