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!
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.
