I just realized that Number Google Results is not working. The problem is with the new structure of the Google search query string. Before, if you were searching for:
"google"
...the query would have looked like ?hl=en&q=%22google%22
Now, it looks like webhp?hl=en#num=100&hl=en&q="google"&fp=randomlettersandnumbersthatmaybeusedfortracking
*The num=100 part is the number of results that I have set in my preferences.
The good thing is that the old search format still works. You just have to enter your query in the address bar. Either Google needs to officially partner with the author of the Number Google Results script, or Google should just number their results. I'm tired of updating the script after it stops working.
