I have written before about Firefox and how valuable I think this website browser is as an educational tool. I am using the 4.0 Beta version of Firefox and it is incredible (http://www.mozilla.com/en-US/firefox/beta/)! Fast, fast, fast! If you love Google Chrome, you'll adore Firefox. The speed has just amazed me. If you don't have it, run, don't walk to download it!
However, there is so much more to Firefox since you can use "Add-Ons" to enhance the way Firefox works for you.
With this in mind, I have created a collection of must-have Firefox add-ons to share with you. I'll be adding to this collection. For the most part, I require that the add-ons be spectacular and work with the new beta version of Firefox. In one case, Zotero, you need to go to their website to download the Beta version of Zotero that works with Firefox 4. I did and so far no problems at all. Please know these are easy to install and use.
I will be adding to this list so I hope you will become a follower of the collection and give it a "thumbs up" by clicking on the two links at the collection home page as shown below:
