I am using Firefox, IE, Safari, Opera and Chrome. I am a web coder, I have to test the codes with them. I hope there is only one browser in fact.
Last month when I worked as coder in a web design company I used FF2, FF3, Opera, IE6/7/8 Beta, Safari and Chrome. Usually for browsing I'm using just FF3, but when working then again the above mentioned.
Nowadays I love Google chrome. Although it is having few lacunas, it is perfect fit for NXG (Next Generation) webmasters like me...
Total 3 , ie core browser, ff core, chrome core. lol There are many browser of tab features in my place. I use at least 3 ie core browsers now.
I use 3 browsers: Firefox 2, IE6 and IE7. 99% of the time I use IE7. The others I use for test purposes.
I too use all of these too ; 1. Firefox 3 2. Firefox 2 3. Internet Explorer with IE7 Pro features 4. Opera 5. Google Chrome
