Which adblock you using? Adblock plus?

If you are using adblock plus open the addon bar and you should see the icon on bottom left corner otherwise open the addon manager and disable it from there.

Don't trust that website it's a scam https://www.mywot.com/en/scorecard/movies70.com

If you have Avast antivirus you may have Adblocker without having an icon and without knowing you've installed it. (like me!)

If you have Avast, click on its icon (a green circle, orange number thing) in the top right side of the Firefox screen.

When the Avast window opens, at the bottom it should say "My Avast" and "Settings" Click on "Settings" In the new window, find the item that says Block ad tracking by default, and click to remove the check mark. Click on the Save button.
