This extension can help you dealing with Dailymotion Age Gate option. No need to change any settings, just install it in your Browser and Open DailyMotion.
The thing is that Dailymotion has a default feature called Age Gate that prevents you from viewing videos deemed “for adults”. So, when Age Gate is ON you can watch only child-friendly videos when turning it OFF you confirm that you are an adult of legal age in your country and free to watch any videos that may need adult’s guidance.
How it Works
But when Age Gate is Off Dailymotion video Thumbnails appear blurry… This add-on will unblur all Dailymotion Thumbnails so you will be able to see everything.
