Ahh, thought it had gone but it’s back again. So it seems to flag the alert at the first visit of a website, but then doesn’t for any repeated visits in the same session (i.e if you haven’t logged out or shut down).
I have nothing blocked in my uBlockOrigin or uMatrix firefox add-ons, interestingly livescore.com is allowed in all regards in uBlockOrigin or uMatrix add-ons. See uMatrix screenshot.
Hm that is very strange. Given it appears across multiple sites it does seem to be related to the banner (Thanks for your insight into this David). What would you suggest is the best next step? And do you think it poses any serious danger?
