Having recently upgraded to Ubuntu’s latest offering “breezy badger” from “hoary hedgehog”. (If you want to do this open your sources.list in vi and :%s/hoary/breezy/ then apt-get update & apt-get dist-upgrade. If you don’t follow that, ignore it) I now finally have firefox 1.0.6 so I thought I’d have a look through my extensions, removing the ones I don’t use and make sure the rest are up to date. I was left with 9 extensions that I have come to rely upon.

• Mouse Gestures. Almost indisposable for it’s one feature of being able to expand images.
• StumbleUpon. Gives you an extra toolbar for “stumbling” around the web, which is a suprisingly good way of finding content that’ll interest you.
• del.icio.us. I don’t rely on this one hugely, but it makes posting bookmarks to del.icio.us much easier.
• Bloglines toolkit. Notifies me when there are new articles that I have to read on bloglines.
• Adblock. I barely notice this one it does such a good job.
• Linkification. Turns URLs in web documents into clickable links, suprisingly useful, again you forget it’s working in the background.
• SessionSaver. When firefox crashes you don’t lose all those tabs.
• User Agent Switcher. Luckily not many sites exclude non-IE visitors any more, but if they do, a few quick clicks sorts that all out.
• BugMeNot. When you don’t want to have to sign up to use every site on-line this tool makes life much easier

I have also just come across a new extension which has a lot of potential to become my favourite extension of all time. That’s GreaseMonkey it allows you to modify the way websites work, which means you can do all sorts of things a lot of great examples can be found here. So far I’ve used only one script which allows you to modify google image search so it links directly to the image.
