Here is my list of firefox addons, I hope you find something that you can use.
5. IE Tab
Love it or hate it, you need to use IE for certain sites. Anything Microsoft, for instance. Just set those pages to use IE Tab and you are all set. Also, adds a nice little button to “switch the rendering engine.”
4. Tabs Mix Plus
Great little add-on that add all the basic tab functions that are missing from Firefox. The #1 for me is being able to set what happens when you open a new tab. Has a replacement session manager, too.
3. FireShot
Fantastic screenshot capture utility for webpages. First, it gets the whole page, not just what you seen on the screen. Also, allows you to annotate and save, e-mail or print. Very nice.
2. Del.icio.us Bookmarks
All the fantastic-ness of Del.icio.us, plus browser sync, too. This replaces Foxmarks for me. Now, all my bookmarks are integrated, tagged and searchable. If you want to see your bookmarks in a whole new way get a del.icio.us account and load this add-on up.
1. Web Developer
Far and away number #1 on my list. I couldn’t develop webpages without this anymore. Helps you see and manage all the pieces of a webpage. Cookies, css, scripts, images, colors, etc.
