Firefox is one of the best browser one can get,its fast, secure and highly customizable.There are lot of firefox addons which can add more functionality into the browsing.I was using opera in dial-up,and it was slick and fast .When i got BSNL Broad Band i used to browse often and felt the need for more options to configure the browser to my browsing style,so switched to Firefox two years ago,even though it was heavier than opera it was easy to configure and has lot more option. Opera is a good browser but, there are some things that i do, which is only possible with Firefox,like changing the background of websites to my desired color depending upon the color of the visiting websites background.
So here is a list of very useful Firefox addons that i currently use with my browser.
