On the hunt for the best open source resources and more

I make a living by building website/apps so i really like to do some things fast and easy that’s why i use a couple of FireFox add-ons in my FireFox brouwser.

By using add-ons in my FireFox brouwser i can test, validate, debug, measure, autofill forms, upload and much more in my brouwser without using other applications/programs(i dont like a crowded toolbar). I will name a couple of them which i really like and find very useful.
