Here’s anotherhandy tool for web developers and for the curious: MetaTags
Panel. It’s an extension for Firefox that will show you the information that’s hidden away in the source code of
most web pages, especially the stuff between the <head> tags like description, keywords, and links. It also shows
much of the information usually shown in Firefox’s Page Info dialog. It’s not the prettiest extension by any means, but
it is handy.
