The best feature I ever wanted in a browser is the ability to load extensions which can do some little wonderful things. Firefox is the browser that give me this feature – in any platforms that it supports (Linux, Mac, Windows). I wanted to recommend some extensions that I frequently use here. Those are the extensions that I spared them from the fate of uninstallation. Some of the extensions do slow down the Firefox browser, so I recommend only keep the one that you are using it, and uninstall the one that you find it less useful. Second, check and see if there are any updates for your extension by going to Tools -> Extensions -> Update. Must Have:

Gmail Notifier – Check Gmail for new emails and notify you on status bar with a nice little icon. Tab Mix Plus – I feel unorganize if I have new link opened in a new window. This extension help me to overcome that. delicious – Provides very quick short cut key (Ctrl-Shift-S) of adding a site to your del.icio.us bookmark. Highly recommended. GreaseMonkey – Able you to install user scripts to change any web sites’ behavior Google Toolbar – Provides feature like PageRank, dictionary and spelling check.
