A week after Apple announced that the latest version of its Safari browser loads some websites 80 percent faster than Google Chrome, Mozilla is making some lofty claims about its own Firefox browser. This is not an official Mozilla release. It’s a browser created by a third party based on original Firefox framework.

  • Crash report
  • Skia Graphic engine
  • WebM
  • Opus Codec
  • WebRTC (enables web browsers with Real-Time Communications capabilities via simple JavaScript APIs)
  • Javascript Debugger
  • GamepadAPI
  • Intl object  for the ECMAScript Internationalization API
  • Web App Sync
  • Health report
  • Firefox Devtools with the Social API
  • DirectShow
  • And a lot more.

What makes firefox equals to chrome?

Firefox 54 has opened up its upper limit of processes from one to four, which are four less than the numbers used by Chrome browser. You can also customize it to be more by entering “about: config” in the address bar and adjusting the settings themselves.

The company claimed that the first 4 tabs use those 4 processes, and additional tabs run using threads within those processes. Instead of creating their own memory, Multiple tabs within a process share the browser engine that already exists in memory.

On Windows 10 64bit processor, Chrome used 1.77X memory as compared to Firefox while it used 2.44X memory on 32-bit Windows 10.

MacOS (64-bit)- Chrome used 1.36X memory as compared to Firefox.

On Linux (64-bit), Chrome used 1.42X memory as compared to Firefox.

Safari browser on Mac uses a significant amount of memory as compared to Firefox, as does Edge browser on Windows 10.
