I’ve come across this topic so many times and I thought I write a little post with my two cents on the topic.
Well, as a web developer I use, wait for it… every browsers.. yes when it comes doing any html/css/javascript I test on all of them. That’s my first thought on the subject and the reason I say this, well if your debugging javascript and it works on your lovely Firefox / Chrome / Safari but not on your IE (shudders) then what you going to do? Go and tell all the users they have to use anything but IE or are you going to use IE to debug?
I use Safari for most of my development process. Its fast and reliable on my machine (PowerBook G4). Every now and again I need some extra fetchers that I will find on Firefox that I will use. You might find me using Firefox a bit more if it didn’t run so slow on my laptop. That would be my point in the end of this. What ever runs best on your machine and has the required plug-ins is the best browser. Running a browser that is 3 times slow than another because its the best browser is not a good idea.
Find out which browsers runs best on your machine, make sure its got the required plug-ins for what you are doing and use it. That is the best browser to use. get it? got it? good.
