Simple, concise, works well, helps me saving time

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.

Best way to keep track of what you actually get up to on the internet all dang day - warning: may be eye opening.

Using the latest 57.0b9 on both standard and developer editions of Firefox for Mac, after installing the RescueTime add-on I can link it to my account just fine, and if I click on the icon in the toolbar the summary does correctly identify which site I'm on.

*But* it never logs any time on these sites. If I visit a site I've not seen in Chrome that day it always reports it as being my first visit. If I visit a site I've seen in Chrome it reports the previous total time spent there but never increments.

Good overall addon, and now works with Firefox 57+
