SEO and SEM Firefox Plugins

Here is a list of my favorite firefox plugins that I use all the time. I got the idea from jimbo over at LBE. I am now using this as a reminder to myself if my firefox ever dies on me and I need to re-install them.

• searchstatus 1.15 - displays pagerank and alexa ranking, also allows nofollow links to be easily highlighted.
• roboform - fills in forms/stores passwords (paid). I could not live with out this program.
• gmail manager - allows you to manage multiple gmail accounts and shows their status
• split link - supposedly shows you where a redirect link actually redirects you. Liek the poor mans version of HTTP Watch used for IE.
• IE Tab - allows you to open IE windows in firefox, good for adcenter
• Duplicate tab - allows you to duplicate the current tab to a new tab or window and keeps the history
• colorful tabs - ads som ecolor to multiple tabs
• tabbrowser preferences - control over tab usage
• bugmenot - fills some registration things with accounts other peopel created, good for newspaper sites
• user agent switcher - lets you change user agents, good for finding out if someone is using bot cloaking on a website
• del.icio.us - portable bookmarking
• sage - rss reader
• ie view - launches the site in an IE browser
• web developer - allows you to turn of css /java etc
• pearl crescent page saver - allows you to screen capture the entire webpage (including things you have to scroll down to) as a png file. this is pretty much an awesome plugin, it allows you the same features of a paid screen capture program…it is great for documenting changes to a website for a client or designer. Another way to describe it would be full page print screen.
