If what you are saying was true, then Firefox should have dominated over IE. Did they take over a large share of the market? Yes, after fighting and fighting for years on end. Chrome just came out, and after putting it on their home page, suddenly their marketshare skyrocketed. I believe that if Google had to put it on a different URL, it would not have gotten the adoption it has now.
Techies installed it because of how much faster it was. Then they installed it on all of their parents/grandparents/siblings computers.
I jumped from Firefox to Chrome with no hesitation when I saw Chrome blazing through multiple tabs without any slowdown. At the time Firefox was crawling on like a snail. Now, years later, I jumped from Chromium to Firefox because I could no longer use the browser to preserve control over certain web pages I needed to use.
No it wasn't.
Firefox has always been significantly better at memory usage than Chrome. Here is a benchmark from 2012 [0] and Firefox's memory usage only went down after that [1]. On the other hand Chrome is infamous for its extravagant RAM usage ([2] and million other web search results). Only in the last few years Google have started to pay attention to Chrome's memory use.
