Sheesh! Rated 5 out of 5 stars

The funny thing is I am almost done migrating from Failfox to Palemoon and I discovered this one because I still have work to do. The ridiculous idea of putting the strange mysterious gray object is yet another bad idea in a long string of them by Mozilla.

Thank you for quickly spotting this and issuing a fix to their stupidity!

** EDIT** I just put it on PM too. PM skipped the gray object mistake but I like the strong color option. This looks like a keeper!

** EDIT 2** It definitely is working in PM and I believe strongly that it is the community that is going to keep things afloat. Thank you for having your thinking cap on!

This review is for a previous version of the add-on (0.6). 

Thanks for the rating

If it doesn't already work in PM, it should be easy enough to get it to.
For the record, there's a developer working on an add-on that returns the favicons and restores highlighting.
I'll announce it here in the description when he releases it.
