Following on from my recent post about making firefox do stuff, I decided to work out how to make firefox extensions, and subsequently found an article about the very subject!

Extensions to Firefox are made by making a .xpi file, which consists of javascript, rdf and xul.

It looks daunting, but eventually makes sense, the article gives a very precise example of creating a basic extension.

Using this information, I have created 2 firefox extensions, the first one is the Open as URL thinger from my previous post, the second is Find on Map, a handy extension to open a search on Google local (UK) with the selected text, for example a postcode, or a place or town name.

e.g. YO11 1TW, or Scarborough, or even harcourt place.

You can install the firefox extensions from my firefox extensions page.

Hope someone finds them useful! :)
