This is the best (only) way I have found to do it with the new google search results.. Ie: instant preview, instant search, etc.
All of the new features that google has added has broken other add-ons that I have used. For it to work now I use two add-ons in conjunction with each other. OH, three actually..

The key to getting things working is to return google to it’s glory days when it didn’t have all of the extra stuff. You can do that with one checkbox in the options for the google enhancer add-on.
You also need to install the greasemonkey add-on and then restart firefox. After you’ve restarted you can navigate to the site where the greasemonkey script resides that will number the result for you. You could also just turn on the numbering option in the GoogleEnhancer options
but it wasn’t working for me for some reason. Also, when it did work, it would include numbering for the blended results which would throw off the regular numbering.
To install the greasemonkey script you click on this button in the upper-right-hand corner at http://userscripts.org/scripts/show/11213
Then you get happy results:
When the search results include a 7 pack, it does not number those. But when we get blended results as in the image above, it does number those results, which is not the most ideal, but beggars can’t be choosers.
