Not sure why it not working anymore, maybe some conflicts with other plugins?

0.1.2.1 no longer does the job, and 0.1.5.1 is not available for Firefox ESR 45. Looks like the eternal hunt for working addons that fix crap on the internet just started again.

Please fix.

Great addon, does its job.

The 61kB download size made it look really promising, but despite many attempts, the install button was permanently grayed out :(

It works out of the box and it helps my youtube experience a lot.

It's also very simple and clean, at least from my last inspection.

A good addon.
