That's some revisionist lies. Slow, crashy, a memory pig with a big leak problem, stuck on a single process architecture. It was none of fast or modern. Whether it was extremely nice to use is debatable, but lots of people rapidly voted by switching.
It very regularly crashed and took down the entire process.
It's fine to lament the Chrome monoculture, but we misdiagnosis it if we don't remember the seeds were sown via Mozilla's incompetence. They made it crystal clear they couldn't and wouldn't do better, and the next 5 or more years made that inarguable.
As one would expect of a browser made by the world's largest advertising corporation.
Currently I am feeling this too but only for one site, GitHub. Which is where is spend most time during the day...
Quite sad, I don't know if it's GitHub's fault or not but Firefox needs to figure out what's going wrong here soon or people like me may be literally forced to Chromium.
But Chrome won the vast bulk of its market share not because it was technically better in every way, but because they spent much more on marketing at the exact time IE entered terminal decline.
Also had safari 5(?) on windows because I liked seeing a progress bar for page load. Which opera 12 also had.
Maybe I just like progress bars.
