I like Firefox but I have had to stop using it due to frequent crashes.
I get the feeling it is due to add-ons but I am not going to play around with disables to solve their problem.
Searching the problem it appears the problem is widespread and Mozilla is on the decline while Chrome is trending.
IE seems to be the most stable of the 3 but I have become annoyed with MS for various reasons and I have a hard time starting IE instead of Chrome. My current solution is to set IE as default but use Chrome for browsing.
Hard to imagine a computer world without Mozilla.
