Finding yourself short on words when it comes to describing that really cool Web page you just found via keywords?
Now usually one or two might do you, as far as keywords go. Every so often though, you just can’t think of any good ones to use. That is where the KGen extension for Firefox comes in.
KGen (Keyword Generator) is an extension that allows you to see what keywords are strong on visited web page. Than, you can retrieve them for social sharing (tag filling) or webmastering/SEO.
