Firefox + Firebug is to some essential
I realize that I'm a very small minority as a developer of a web centric engineering application. I have the luxury of telling those who want to use what I develop that they will have to use whatever browser I use. That way I avoid the browser incompatibility mess. Currently that browser is Firefox because the combination of Firefox + Firebug is the best I know of for what I do. If there's better, someone please tell me.
Also, for people like me, social media is a waste of time. For example, I've turned off all of the emails from Facebook. In all of the hundreds of emails I received concerning those who friended me or who had convinced me to friend them, not one was ever of the slightest interest to me.
Perhaps it's a case of XXXXXX browser for some but not all, and you can replace XXXXXX with any browser you wish?
