lol...i use a few, most of them aren't worth it, but some of them are great for making browsing easier
i will...simply..an addon is something you can download from your browser, to enhance your browsing experience. For example, i have an addon which means that rather than pressing the back/forward/new tab/etc buttons, i use the mouse in different ways so that i can achieve those things more quickly. eg. To go back a page, i swipe the mouse to the left. It just means i don't have to be as accurate with the mouse as i would have to be if i was looking for the back button. In other words, an addon is not something you can't run on its own, it runs with a browser to make it easier to use, or to change it's appearance or to add brower buttons. There are thousands of different addons for Firefox. I think i use about 6 lol
Then you can have desk top gadgets which are also useful, like currency exchange gadget , unit conversion gadget , translation gadget etc!
The only plugin I use is AdBlock. Best piece of software ever!! No ads on any sites pretty much, it changes your life!! http://adblockplus.org/en/
But does it put cookies ofr whatever and expose your computer to viruses - _i'm never sure what to trust
