Then add new features that lead to increased memory usage (usually due to new security features that require large amounts of memory, or due to prototype features that have not been optimized), and so on. The reason is that every few months Mozilla developers review Firefox’s memory usage and try to optimize it. He said that occasionally a certain version of Firefox will consume more memory than Chrome. In the post comments, there was a reply from a member of the Firefox development team.

Some people said that they would freeze when they opened 2-3 tabs with Firefox, but Chrome handled the same number of tabs very easily. Many users in the replies said that they encountered the same situation. All the browsers are the latest versions at the time of writing. Then, this user enabled the extension of Firefox, at this time it consumes about 500MB of memory, while Chrome opens the same number of tabs, the memory usage remains within 300-350MB. We’ve put together a RAM and CPU usage test with 10 websites loaded simultaneously on to 10 different popular web browsers Avant Browser, FlashPeak SlimBrowser, Maxthon, Mozilla Firefox, Internet Explorer, Google Chrome, Opera, Green Browser, Apple Safari and finally Pale Moon. At this time, the memory usage of the two is as follows, Firefox takes about 240MB of memory, and Chrome takes about 100MB of memory.

At the same time, keep all Chrome extensions enabled and only open one tab. He first disabled the Firefox 75 extension and did not open any tabs. In 2021, a new feature called Sleeping tabs was introduced.This will drastically reduce the amount of CPU and RAM usage. Though it is based on the Chromium project, it had its share of difficulties. If several tabs were opened at the same time, the amount of memory required also increased. The reason is that a user posted a post on Reddit saying that he made a comparison and found that Firefox 75 takes up more memory than Chrome. Microsoft Edge had the notoriety of having high CPU and RAM usage after some updates. However, after the release of Firefox 75, many users said that upgrading to the latest version of Firefox consumes more memory than Chrome. In contrast, Firefox, which uses less memory, has become an alternative for many people. Chrome was known as a “memory killer” because of its high memory usage.
