Rated 5 out of 5 stars
Since Firefox 57 I've switched over from Chrome. This extension initially did not log correctly even though the notes here said it added support for Firefox 57. However, I recently received an update to my rescuetime OSX app and now everything works perfectly as expected. Thanks rescuetime. This is now a 5 star extension.This review is for a previous version of the add-on (3.1).
