Browser extension
I am trying to build a cross browser extension that will search for numbers through the page and do some processing. It should work like the Skype extensions which scans for numbers and converts them to a click-able number, which on being pressed initiates a call through Skype. 

I am new to extension development. 

Please suggest me which framework I should use and yes, and will it be possible to convert them to click-able icons.
