Strange XSS notice

Espresso · Post by **Espresso** » Sun Dec 10, 2017 10:33 pm

I receive an XSS cross-scripting warning for thumbs.mic.com when I simply open Firefox 57.0.2 (to a blank page, not the FF start page), which is weird because no website has been visited yet. The warning also appears sometimes when searching Google (before I click on a link), when opening the bookmarks dialog (Shift-Ctrl-B) and when visiting some websites. It is getting pretty annoying. Is this a bug with NoScript or has my FF been compromised by malware?
