On the surface, the site changes are minor. Underneath, the mark-up is drastically improved: I’ve removed a lot of superfluous html; improved semantic structure; cleaned up the style sheet; started using header tags properly; removed all instances of the img tag (except when actually displaying inline images — no more dividing lines and such); and, added a number of links to enable the Mozilla site navigation bar. It’s a useful feature. If you are viewing individual entries, you can navigate through them all using the ‘next’ and ‘previous’ buttons. Amongst other things.
There is a slight issue with Mozilla, though. It seems to cache the randomized header image on load, even if the image forcefully sends “no cache” headers. I’ve tried a few things, and will have to look into it a bit more first, but I’m pretty sure that it’s a bug on Mozilla’s side, not mine. Looks like I might be reporting my first bug. How exciting. Or not.
