Great idea for an add on, but unfortunately it's broken for use with google because of problems with domain-specific blocking. There have been tickets open since mid-2018, but there doesn't seem to be any interest or progress in fixing them.

PS - Sorry if my review seems harsh, but given how dominant Google is (and given how aggressive they are with tracking) shouldn't the information page mention that it doesn't work with Google? Just seems like a prudent thing to do to help people with basic "surfing safety." Don't get me wrong, I appreciate your efforts on the tool, and it looks like it could be very handy, but I was pretty unhappy when I thought it was performing an important privacy protection function it wasn't.

Unusable if you need to use website forms filled in with full url, like there ones on ssllabs.com - i dont want to whiteliste every website with a form like this (bugfix from dev)
I remove this addon and look for a better one

On Firefox ESR 52.4.0 on Debian Stretch, does not clean urls, does not show a right-click menu option to copy neat URL (as in CleanLinks), can't figure out how to use it -- or if it usable at all. The toolbar icon is useless, does not make any difference.
