> The thing that I don't understand is why the world has switched over to Chrome leaving Firefox behind

Reasons why I, a former Firefox promoter switched to Chrome:

1. Speed. Chrome was blazing fast compared to other browser

2. Stability: Chrome could have a tab crash without bringing down your entire browser.

3. Really good developer tools that were superior to Firebug. As a matter of fact, Chrome Dev tools were my gateway drug as I'd use Chrome for work and Firefox for personal browsing, and the gradually shifted entirely to Chrome.

Situation has changed dramatically wrt points 1 and 2 since years, however. As for 3, I'm no web developer so can't comment on this.

The dev tools are really good in Firefox and its browser forks.

One or two devtool features are better in firefox, but when I gave it a good try a year or so back I had the devtools get stuck / crash / fail to find an element that's onscreen moderately often - enough that I'm not keen to use it for work by default.

Chrome is still significantly faster for me on multiple computers. Even now, Firefox can't smoothly scroll though this very page [1] without obvious jitter; no browser should have trouble with that.
