Ayala says that he only estimates and does not calculate the exact time, just open and see how long it takes to load a page. Since WiFi has been turned off, the way you calculate it will be based on the time required to download the 'Server Not Available' page.
Regarding how to measure memory, he said: 'With memory, I waited a minute after I turned it on and then took the value from about: memory. I chose 1 minute because I found that when I first opened up the memory, it usually increased in 1 minute, then it would stabilize for a long time after that. '
He experimented with many versions of Firefox, from 20, 30 to 40, 50, 56 and interestingly, until version 51, the speed and response time were low. Once launched, Firefox may attract more people and chase Google Chrome closer in the battle between browsers.

What we need to do now is sit still and wait to see if it is true that Firefox will open 1,500 tabs and still use it well?
