I use a lot of firefox extensions. You might call me a power user. Yeah, that's right, powerful.
Here is the list of my favorites. They are broken down into extensions that make Firefox better, those that make my general life better, things for "geeky stuff" and things for my life as a web developer/sysadmin/competitve webmaster. Yeah, I'm competitive. My stable of sites is better than yours!
- Cute Menus - humans recognize colors and images faster than words.
- Download Statusbar - I want the information compact, in an overview, and readily visible. I hate new windows.
- Flashblock - I hate flash. It's amazing how much better the internet is without flash.
- Google Gears - Since I'm in places without internet pretty regularly, it's nice to be able to get my Google feeds in an offline mode.
- PageStyle2Tab - again, humans recognize colors and images faster than words.
- Image Zoom - Firefox lets me zoom text, image zoom lets me zoom images. Duh.
- Locationbar2 - Prettify the URL bar. Also happens to make it safer by clearly identifying the domain and downplaying the importance of subdomains (i.e. the phisher phavorite ebay.com.shadysitestealpasswords.com/enter-username is clearly visible as "www.ebay.com" as a subdomain of "shadysitestealpasswords.com". Whoohoo!
