1. SEO Link Analysis – Enriches the link data in Google Webmaster Tools & Yahoo! Site Explorer by showing the PageRank of the linking page, the anchor text user and whether the link is nofollowed or not.
2. Screengrab – Allows you to save webpages as images. It will capture what you can see in the window, the entire page, just a selection, a particular frame… basically it saves webpages as images – either to a file, or to the clipboard.
3. StomperTools – StomperTools features SNRanker, a visualization of Google, Yahoo, and MSN/Live for a specific query term using SVG. See how you rank! Useful for search engine optimization (SEO) assessment as well as exploring a topic. It also integrates with Stomper Scrutinizer, an Adobe AIR browser with a built in simulation of human vision, if installed.
4. TableTools – TableTools sorts, filters or copies any HTML table. This extension is the perfect first-glance tool for HTML data tables, providing better sorting and filtering capabilities than MS Excel (and directly in FF!), but if you need to make a graph or sth., just use the extension to copy the whole table into Excel!
5. Better Google Analytics – Enhances Google Analytics with a compilation of user scripts.
6. Save Complete – Saves a webpage completely, providing a better alternative to the flawed built-in save functionality of Firefox.
7. IE Tab – Allows you to embed Internet Explorer in tabs of Mozilla/Firefox.
8. KGen – KGen (Keyword Generator) is an extension that allows you to see what keywords are strong on visited web pages.
9. Live HTTP Headers - View HTTP headers of a page and while browsing.
