Works Great on Firefox 55.0.2 For Me! Rated 5 out of 5 stars
I'm wondering why it's not working for some folks. Does the operating system make a difference? I'm using a Lenovo i5 (notebook) laptop with operating system: Windows 10 Home (64 bit). What a godsend this add-on is!This review is for a previous version of the add-on (55.0).
