yourbrowser.is - a free tool for checking customers' browsers
I made this tool for myself after having to explain a customer how to check his browser make & version for the 1000th time.
Then I made it look better and added a feature of creating own checker pages for other users.
I always love to see when people care about every detail of their code. +1 for automatically updating my current viewport size onResize!
Keep up the good work!
