Firefox 4 knows about:me (and you)
I'm a big fan of data analytics which is why back in 2009 I was excited about a new potential Firefox feature called about:me.
The basic idea was that the about:me call would provide users with information about their browsing habits and usage.
Originally about:me was a feature that was under consideration for direction integration with Firefox 3.6, but that didn't happen. Instead about.me became an add-on for Firefox 3.6.x.
This is a great relief to me, as it means that about:me has a future.
Too many 'maybe-features', like Mozilla Prism for example, get relegated to the add-on dustbin, never to progress to Firefox 4 (there is no Prism add-on for Firefox 4 which is a real shame).
