For what it is, it works well. That being said, I decided to uninstall it for a few reasons...

1. Apparently, all the definitions are taken from a Google search. Granted the definitions themselves are fine, but it would be nice to have a larger pool of sources to choose from like Merriam-Webster or DuckDuckGo. Defaulting to Google works I suppose, but I don't think a Dictionary extension needs Google.

2. On that note, I can basically recreate the functionality of this extension using Swift Search Selection by adding a source like Miriam-Webster as a search engine, to say nothing of adding it as a search engine to the Firefox Browser itself.

Still gets the four stars because it is a good extension, but I decided since I already use SSS a lot anyway that I'll just keep using that and leave this on the shelf. Thanks for the good times.
