Been using several  very useful Firefox extensions that have made my life considerably easier lately.

The first is called Duplicate Tab, which allows you to create a new tab that duplicates a currently open tab – along with all its history. I’m finding this very useful when im writing SPARQL queries against our platform where I invariably end up having lots of tab’s open because I often write a query, run it, but then want to be able to keep the results open so I can write another query but to do that I have to manually open a tab, navigate to the bookmark … and thats tedious when your trying to get stuff done. Its so much nicer being able to run the query – and then duplicate the tab, hit back in the duplicated tab and now I have one tab with the results in it and one tab with the editing pane in it … away I go!

The second is the Google Preview extension. When you do a search in Google this extension inserts preview thumbnail images of websites, which I find quite useful.

The final extension is Pearl Crescent Page Saver (basic), which allows you to take a screenshot of the current page your viewing in the browser as a png.
