Some useful snippits for Macintosh users:
To have more control over which websites can automatically load and start flash content:
ClickToFlash This makes Flash content on websites show up with just a button in the middle saying Flash, and will always do so, i.e. the Flash content is blocked until you click it. You can whitelist websites so that their content is automatically loaded if you wish. It provides a convenient way of stopping those annoying Flash based animated adverts from popping up all over the place.
Next on the list:
To stop other types of adverts from appearing:
GlimmerBlocker This blocks advertising web servers. It uses filters that can be downloaded from various websites linked from the GlimmerBlocker website. It is system wide, i.e. it isn't a Safari add-on. It acts as an HTTP proxy, and therefore works with most web aware apps. Some may need manual tweaking, like FireFox.
That is all, MacBoero... Out!
