I am odd one out. I use MSIE, Opera and Firefox in that order. I do not like tabs, so they are not a selling point for me.
IE for me. FF is unstable and buggy. Plus IE7 has tabs, thats the only reason I used to use FF was for the tabs, now that IE has them theres no reason to use FF
Firefox for me because its faster, opera is quite decent also. I would compare IE to a steaming pile of brown stuff myself, it tends to ignore html code which isn't really the best trait to have in a browser.
I've been using Firefox more or less since it was available. I like having the same browsing experience whether I'm on my Mac or PC.
I got into FF for the tabs, but the extensions where a nice addition. I used to the Avant browser add-on for IE, but gave up when it would lock up all the time for me. Also, asking this question in a techish forum will give you hugely skewed results towards alternative browsers.
i use ff, but it is starting to gring my gears because it keeps crashing. I have heard a few people have this problem but is it widespead? Im just wondering if its some of the extensions i have installed.
