I've been visiting Think Progress safely for years. Now all of a sudden I get the following message from Mozilla Firefox:
Reported Attack Page!
This web page at thinkprogress.org has been reported as an attack page and has been blocked based on your security preferences.
Attack pages try to install programs that steal private information, use your computer to attack others, or damage your system.Some attack pages intentionally distribute harmful software, but many are compromised without the knowledge or permission of their owners.
I don't know if they've been hacked, or if this report is malicious mischief. Either way, it's bad.
I have emailed them at scoop@thinkprogress.org. I've also reported it to Mother Jones and Huff Po.
Hopefully, this will be fixed quickly.
