But the easy process is to use WhatFont, it is a service which allows you to find out the font used on any webpage with just hovering your mouse on the text.
It fully support Firefox 3.6+, Chrome 9+, Safari 4+, Internet Explorer 9. I had tried it on some webpages and I am satisfied with the result, I put test on a webpage which consist of lots of different fonts and then as I hover my mouse over the different texts it keep on showing the name of different fonts used on it.
As I took screenshot using print screen button that’s why cursor is not showing above screen but as you hover your mouse it shows the name of font.
