Yes I figured that out 1st thing this AM as I tried all links to the particular post.
It only happens after I open the post and access the redirector link below the title.all the other links are fine.
Chrome works OK Safari don’t
My ? remains who’s problem is it,Mine,Safari,FR,Google?
Tried it on explorer, no issues, and no issues with another laptop running Lumbuntu and Firefox.
Ran Malawarebytes and found nothing, it's definitely on the redirect page and only certain browsers.
Got the first pop-up when I went to look at a source article about the radio "inventor" , but that is probably coincidence
I’m on Firefox (Linux) and have not bumped into that malware warning.
