Firefox Promises Less RAM Consumption and Better Performance With the Firefox 54 Version

By June 15th, 2017 AT 2:21 PM

Mozilla’s Firefox is not a go-to option for users who are looking for a daily usage browser. Even though the browser has many features when compared to its counterparts Google Chrome and Apple Safari, users just don’t prefer to use it because of the aggressive memory it consumes.


However, the company has released a new version of the browser- the Firefox 54 on Tuesday claiming that they have finally ‘achieved a breakthrough.’ With Firefox version 54, Mozilla promises less RAM consumption and faster performance, unlike the previous versions of the tool.

Nick Nguyen, Vice President, Product, Firefox, in the blog post said “In order to achieve these improvements, Firefox 54 uses up to four content processes as part of Mozilla’s ‘E10s’ project, instead of the one used by earlier versions. In simple terms, this means that a complex page, with extensive multimedia content, now ends up having less impact on responsiveness and speed of other tabs.”

With today’s release, Firefox uses up to four processes to run web page content across all open tabs. This means that a heavy, complex web page in one tab has a much lower impact on the responsiveness and speed in other tabs. By separating the tabs into separate processes, we make better use of the hardware on your computer, so Firefox can deliver you more of the web you love, with less waiting, said the company in the blog post.

To make Firefox run even complex sites faster, the company has been changing multiple operating system processes. The old Firefox used a single process to run all the tab in a browser. The current age browsers split the load into several independent processes. Firefox has named the project of breaking Firefox into multiple processes as ‘Electrolysis’ or shortly E10s. Firefox says that E10s is the largest change to Firefox code in its history.


The company also released few tests comparing memory usage for various browsers, and the results show that Firefox used significantly less RAM than other browsers on Windows 10, macOS, and Linux. Take a look at the image for the usage of RAM by the latest Firefox 54.

The Firefox 54 version will be available across all the platforms- Windows, macOS, Linux, Android, and iOS in coming days.

After update it’s using 100-200MB less memory depending on number of tabs. Everyone should update.

I always use Firefox on PC since its just a lot better than Chrome and others (as long as it doesn’t crash when you have opened 50 tabs). This is good news for people like me.
