Google had the advantage of plastering Chrome all over google.com when people performed searches. That's how it got installed everywhere.
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.
[0] Chrome was light years ahead of Firefox in both cpu and memory use for years

Here's an anecdote for you. I worked at a computer store when Chrome was released. People would come in all the time, and they had no idea they had installed Chrome on their computer. They had no idea that it had taken over as the default browser. They didn't know they weren't using IE. Chrome had a super basic installer that asked one question, and it was linked right from Google's home page. I interacted with average computer users hundreds of times every month.
That's how I believe it became the dominant browser. Average people don't care that one browser is slightly faster than the other or has an omnibar.
ALSO, it's mostly that people switched from IE to chrome, as opposed to switching from firefox to chrome.
Here's one from 6 weeks ago.

That, and aggressive bundleware campaign in early-mid 2010s.
Google paid above market rates for authors of popular Windows freeware like CCleaner, Adobe Flash etc. [0]. They even tried to bribe VLC at some point [1].
I'm always baffled to see commenters in HN were aware of Google Search banners but not this bundleware business. I guess it's due to people here having disproportionately high use of macOS and Linux compared to rest of the world.
