Chrome used to be very lightweight, fast and basically unseated IE as the top browser. It got that love because at the time Firefox was bloated and IE had a stranglehold. Chrome was also safer with a process per tab. Chrome made web browsing/dev pleasant like Firefox/Firebug did and it really took off being based on Webkit like Safari which also worked well on mobile. Chrome (and Safari) or Webkit pushed HTML5/Canvas/WebGL/SVG into real world use which changed the landscape of browsers.
Nowadays Chrome is bloated like Firefox was, has a stranglehold like IE did, is now pushing its own market standards and breaking existing open/market standards and generally being a forceful, non respecting to standards, web browser. It sure is unfortunate and another sign that bizdev/marketing/executives rule over engineers at Google now.
I tried using Firefox for Linux for about 6 months last year, but had to give up. I got frustrated with the random UI pauses/latency, random crashes, and broken web rendering (not its fault). On the other hand, Chrome just works, and provides a very smooth, low latency experience on Linux. I don't like that I have to give up my privacy for a decent browsing experience on Linux, but that's the state of things.
Guys who maintain Firefox - thank you. I hope I'll join the FF users once more in the near future.
