I am just like you - ASP.NET developer working on many sites, growing sick and tired of the whole error reporting, bugtracking and fixing loop that we are sucked into daily. And it never gets better. You never know if what you fixed is really fixed for all clients. Your QA guys go over the same issue again and again and verify it, but miss to test in on that specific Mac OSX Safari browser that 10% of your end-users are using.
