|Firefox quantum is better. The only disadvantage it has now is lake of legacy extension support.|
FIREFOX QUANTUM is still in beta mode. In their blog, i am seeing so many matters regarding extensions support, so i think they are currently working on that also. Although there are a pretty good number of people use Firefox for long time. It may be not user friendly for those who had not used it frequently and played with it but nevertheless Firefox also in the completion of BROWSER.
They claim Firefox Quantum is the fastest version of Firefox they’ve ever made. It is twice as fast as Firefox 52 and often faster than the latest version of Chrome in head to head page load comparisons. By using key performance benchmarks, we were able to optimize Firefox to eliminate unnecessary delays and give our users a great browsing experience.
