Cool addon with a spelling mistake Rated 4 out of 5 stars

Really good. I'd love to see a version where it doesn't load until you click the Wolfram button, though. (It is rather intrusive.) If you were doing that, I'd left-align it so that it's above the Google results and uses the full column.

Also, the button says "Wofram|Alpha" instead of "Wolfram|Alpha". Thought you should know! Good work all around, though. :)

This review is for a previous version of the add-on (0.3). 

Hide Wolfram until clicked.

Hi Grant. Thanks for the comments. I've added buttons so that you can switch between Wolfram and the text ads (and Googlepedia if it is installed). It will remember your last choice so if you click on the "Original" button then next time you search the Wolfram results will only load in the background. This feature is available in Version 0.5. And I fixed the spelling mistake too. Oops :-) Thanks for pointing it out.
