Can any one share most useful Add-ons of Mozilla Firefox?
Web Developer Plugin and LeechBlock.
Hard to say. This really depends on what you do or you want to do when you browse. It is not the same to be productive at work than simply browsing around and having fun.
Same with the type of work you do. The most useful plug-íns for a social media marketer will not be the most useful plug-íns for a web developer or a WordPress blogger.

The easiest way to figure out the essential add-ons for Firefox is to take a look at all the built in features in Opera. Those are the features that you most need to add to Firefox using extensions.
For those using Chrome it is just a matter of waiting - Chrome will eventually implement all the same features as Opera, just a while afterward to give them time to see what has been added to Opera and copy it (which is how the essential extensions for Firefox get created as well).
