NOTE: This extension works only with FF builds/version 1.5 and above.
While looking around Mozilla Add-ons today I came across and interesting extension called PoliticianSearch. It was built off the DictionarySearch extension (advantages of open-source) and once installed will add an option to your context (right-click) menu to Search Project Vote Smart…
To use, simply highlight the (US) Politician’s last name, right-click and select the ‘Search Project Vote Smart’ option. Once installed you can try it out now by doing a search on our Governor, Janet Napolitano. If you don’t have the extension installed yet, click here to open the results in Project Vote Smart.
I could find this useful for news and newspaper sites. Complete information about the politician, only a right-click away!
