These are some firefox extensions that I have made.
This extension allows you to open selected text as a URL.
Useful for when a URL is posted, but not as a hyperlink! e.g www.mattstabeler.co.uk
Download and Install Extension 25kb
This extension allows you to search with google local (UK Version) with the selected text .
e.g. Select a postcode and seach google maps with it :D
Same as Open as URL basically, but instead of opening the seleted URL text, it appends the selected texts to the query string for Google Local. e.g YO11, Scarborough, or Harcourt Place
