jquery.mb.browser reintroduces the removed $.browser object in jQuery 1.9
With the new 1.9 jQuery release they removed definitely their $.browser method.
I know that feature detection is better than using user agent sniffing, but for many of you who used the $.browser scattered in thousand of line of code this plugin can solve the problem without changing anything on your code. just place it after the jquery-1.9.js inclusion and it’ll do the work.
You can download it from gitHub: https://github.com/pupunzi/jquery.mb.browser/archive/master.zip
