>First of all I am working on a windows machine. The standard UI elements on Firefox are incredibly ugly, as in they look like something from a java application 15 years ago. Perhaps you are using a version of Windows from 10 years ago? It just isn't the case on Windows 10 - looks great (it uses the system UI elements). >Secondly ... the debugger on Firefox is not working right for some reason. You mean the debugger in the web-based programming environment that you are developing on is not working in Firefox? Is that a fault of the browser? >The last reason: the rendering is a little different between Chrome and Firefox. >My main conclusion is that ... it is going to take more work to really get it to be an all around better or even equal browser. One of your criteria is that Firefox has to be literally Chrome in the way it renders things. I don't think you'll ever be satisfied with it (unless you change your mind). It's already a better browser for my use case: leaner, faster, and has Reader View button in the UI out of the box, which is great in general, but more so if I'm at work. Thanks for sharing your experience, though! I hope that you project ends up working fine in FF as well :)
