I guess they have added some adblock detection-techniques very recently (maybe yesterday ), because a few days ago i have visited the website without problems. I'm using uBlock Protector and it was fixed with the latest version: https://github.com/jspenguin2017/uBlockProtector/issues/425
It's definitely something that is triggered by NoScript. I have Ublock Origin, but not Ublock Protector, installed in FireFox and with NoScript blocking scripts globally I get the same result as in the OP. Disabling NoScript eliminates the issue. Note that website deploys browser canvas fingerprinting (detected by canvasblocker FF extension). Perhaps that has something to do with it.
With Firefox and uBlockO, blocking scripts and 3rd-party-scripts has no effect on this website (self-tested). Blocking of inline-scripts is needed. And if i block scripts globally with uMatrix i can get rid of the issue too. If uMatrix "can do it", NoScript should be able to handle it too
Same behavior with NoScript, there was no warning without allowing ghacks.net. Thats what I saw yesterday before updating NoScript and Ublock origin to their latest versions. After the updates, I can now temporarily allow ghacks.net in NoScript and dont get the warning anymore. Bo
