Etsy Search Engine Shortcut per James

This add-on adds Etsy to the list of search engine shortcuts in Firefox.

By typing "etsy" followed by a space, you are then able to search for products on Etsy.
For example, after typing in the query "etsy jewelry" your tab will redirect you to the search results for jewelry on Etsy.
You can modify the keyword for this extension by going to the Firefox Options -> Search -> Search Shortcuts
