After a long time after the release of Firefox Quantum 57, Mozilla has done some benchmarking tests between Firefox 63 (currently on beta) and Firefox 57 that was launched in last year and says former is faster than latter. FYI, the company has put emphasis on speed for Firefox Quantum, but the at the same they’ve ditched Australis UI and introduced Photon UI to gain performance improvements.
According to Evan, Engineer at Mozilla (automation and Tools) current Firefox 63 on beta has performed well over Firefox Quantum in below benchmarks even after taking their recent upgrade to hardware into consideration.
Firefox 63 vs Firefox 57 Benchmark results
Speedometer: From the graph below, you can notice Firefox 63 (purple) performed well in the speed test.
Startup time test: When Mozilla mesured startup time between Firefox version 63 and 57, former took a lot less time to start, lesser is good.
Evan performed Page load test for top sites such as Amazon.com, Google, Facebook and YouTube and measured the time in ms both versions took to first non blank paint, in this test too like startup time test, version 63 scored low numbers, Yep! Lower is better.
The engineer says the results may vary in real-world tests and goes onto say they’ve conducted benchmarks in an isolated environment (with no network use, fresh profile, and custom prefs), on outdated pages and opinions user may not perceive their startup time result as accurate.
What do you say on about this? Have you seen a drastic improvement in speed or performance in current Firefox when compared to Quantum version? .
