Just upgraded to latest version of firefox - 3.0.5, in Ubuntu from its repositories. Set it loading gmail to check my mail. Mean while, hating the idleness, went on clicking this and that over the firefox window and reached - "About Mozilla Firefox", where I found the following pic, I'm a bit surprised to find something non-mozilla there. Went on to wiki to find who this man is, aah! It's not a single page, It's a m.i.n.i book, which I marked, "read-it-later". If you are curious follow this

Update

It seems to be particular to Noia 2.0 theme, designed/owned by some Thai person.
