$ glancesĪfter launching Firefox and using it for close to half an hour with less than 8 tabs open, I captured a screenshot of glances with processes sorted by RAM usage shown below. I started by running glances and sorting processes by highest RAM usage before launching Firefox, as shown in the screenshot below. Under this tool, to sort processes by RAM usage, simply press m key. I performed a few tests using glances – a real-time Linux system monitoring tool, to view top process by RAM usage. If you open Quantum with just few tabs, let’s say up to 5, you’ll notice that memory consumption by Firefox is fairly good, but as you open more tabs and continue to use it for long, it tends to eat up RAM.
Therefore I carried out an simple investigation to examine Quantum’s memory usage, and also tried to compare it to Chrome’s memory usage, using the following testing environment: Operating system - Linux Mint 18.0ĬPU Model - Intel(R) Core(TM) i3-3120M CPU 2.50GHzįirefox Quantum Eats RAM With Many Tabs Opened
However, after I updated to Firefox Quantum, I noticed two significant changes with by far the biggest update to Firefox: first, it is fast, I mean really fast, and secondly, it’s greedy of RAM just like Chrome, as you open more tabs and continue to use it for a long time.

On many Linux distributions such as Ubuntu, Linux Mint and many others, Firefox even comes installed by default. I have always preferred it to using Google’s Chrome, because of its simplicity and reasonable system resource (especially RAM) usage. For a long time, Mozilla’s Firefox has been my web browser of choice.
