The first step in solving this problem is to make sure you are running the latest version of Firefox. If it’s consuming 2GB or more, however, you are probably experiencing a memory leak. Press Ctrl+Alt+Del and look for Mozilla Firefox under the tab titled “Processes.” In most instances, Firefox will consume less than 1GB, which shouldn’t cause any issues. So, how do you know whether or not Firefox is experience a memory leak? The easiest way to identify this issue is by running Windows Task Manager (assuming you are running a Windows OS). Mozilla Firefox may initially consume just a small amount of RAM when launched, but after a while, its memory usage can quickly rise to 2GB plus, bogging down system resources to a crawl. However, memory leakage is an all-too-common complaint reported by users. It’s a fast, efficient, customizable browser that’s supported by an active community of developers. Does that seem like a memory leak problem, or is that just something being wrong with firefox itself? Sometimes I open it and its fast, other times slow, and i don't know enough to know if that is somewhat normal.Accounting for 23.6% of all Internet traffic in December 2014, Mozilla Firefox is the world’s second most popular web browser ( source).
