Haven't ever heard of it and doesn't yet make sense to me. SEO has nothing to do with what broswer you're using.
It's a series of extensions to the Firefox Web browser that allegedly makes it easier to optimize a Web site for the search engines.
I just installed SEOQuake for firefox today, (I cant post links yet, just google it) it's actually really cool. when you go to a page, you can pull all of it's SEO data like PR backlinks #of pages on the site indexed by google, MSN, Yahoo, Delicious. Inlinks out links alexa rank and age. I think that this is what you're talking about. Check it out it's really cool and free. (I have nothing to do w/ this product) When you go to google, you can also see the stats for every link returned. works w/ yahoo site explorer too which is good for checking the ranking of all the pages pointing to your site and all the pages index by them.
Hey man, it's a tool for the seo, which is some how , same as seo qauke, it gives details about a web page, as well as it helps to feel out the form as roboform does. Just search with SEO for firefox, you will get that tool.
SEO firefox helps me determine my position in SERP rankings in yahoo as well as in google.. like if you search certain keyword, the result provides what is the PR of that site, the alexa rankings and many more! moreover, when you stumble upon any website, you can check if they offer no-follow right from the very moment you see the links because its highlighted in color red.
Aaron Wall now offers another firefox plugin. Besides SEO for Firefox: http://tools.seobook.com/firefox/seo-for-firefox.html he also offers the rank checker: http://tools.seobook.com/firefox/rank-checker/ These don't "do any SEO", they simply are little plugins that help with some tasks an SEO might want to perform.
