I never used Chrome much. I think I jumped from IE5 to Firefox. IE6 only for testing web apps. Frankly nearly everything has been working well in Firefox for a long time. The only two sources of problems are: 1) Long tail experimental sites that use or want to demonstrate some new technology. I find most of them on the home page of HN. 2) Myself and the security/privacy plugins I use. They break some web pages, especially ecommerce and payment workflows. I either go hunting for the correct combination of permissions in uMatrix (I would become crazy soon if I used uBlock Origin for that) or I use that very site in Chrome and the close it. Major ecommerce sites don't have any problem. The long tail ones are weirder in their choice of third parties. However that's an issue that any browser would have, it's not because of Firefox.
