Summary

It won't play Dailymotion videos. "Your browser is not compatible. You may need to update your browser" error.

I tried a lot of experiments. I tried about 30 combinations of settings. I refreshed the page every time. Most of the time I clicked on the Remove button next to JShelter > Global Settings > JS Shield details > A list of websites with redefined JavaScript Shield: > I clicked the Remove button next to websites's , I changed the settings, refreshed the page. I tested many combinations. I also manually tested the settings one by one.

Then I decided to report back here.
the problem persists even if you turn off javascript schield and fingerprint protector. If I turn off or uninstall JShelter from the Manage Extensions page (chrome://extensions/?id=ammoloihpcbognfddfjcljgembpibcmb) the problem should be fixed.
It is completely caused by JShelter.

Turning JavaScript Shield off doesn't help. Setting JavaScript Shield to Recommended doesn't work either. Manually weakening the settings doesn't work either. Turning off JShelter works.
