Here's a list of firefox add ons that give alot of control back to the user.

Yout browser identifies itself to a webserver with each page that it fetches. Sometimes a web server may deny or grant your request based on this useragent string. A site may choose not to "support" a certain browser or it may let googlebot see its pages without logging in.
I was trying to think of a way to keep myself from checking google news every 15 minutes, while at the same time making myself check other websites periodically.
I came up with a solution whereby a perl script uses the delicious API on CPAN to add a tag to bookmarks that contain a crond directive.
This way I can just pull up all my boookmarks with the toread tag when I have time do do some web browsing. I can make googlenews only come up twice a day.
I've been using djbdns for quite a while now to host my domains. One of the nice things about it is the simple configuration file.
I've written a small php script to handle dynamic dns entries for my connection at home. It just reads a template data file determined by the name you give the php script in GET vars, replaces a token with the requested or current ip and calls make to update the data.
I had to modify the Makefile for tinydns's root direcotry to concatenate all the finished data files before calling tinydns-data.
