Not sure how to debug this. Not getting any results showing and instead I get the following:
> No webpage was found for the web address: chrome-extension://pklgmphiapdicmpbgnjnhnlmjpbijlfp/3D
Mind it could be a conflict with other extension.
Maybe, type 'bookmarks' in your omnibox then tab...start typing a search term and results will pop up. Click on one of those results and see if it works.
What JS lib are you using to do the actual fuzzy searching
