CloseReview for Dictionary Switcher by Patrick Smits
Rated 4 out of 5 stars
This add-on is one of those gems you rely on without giving much attention to it. One it's gone you now how much you liked it. It does its work without being interruptive. So I'm really sorry this extension is not compatible with Firefox Quantum at the moment. I hope it will be revived. Thanks!
