This addon does nothing, wasted my time

it does not work

This addon does nothing.

No funciona

Ничего не изменилось. Как проверить, работает ли Flash Player в YouTube? Версия Firefox 52.9.0.

it doesnt work

It does not work. I can not view flash files from Adobe or from my on line courses that were working before the "upgrade".

Does not help at all CPU goes up into 90% and eventually crashes pc due to over cpu use.

Like everything else with Firefox, it only works part of the time. Every time they update this excuse for a browser something gets screwed up.

Useless. Must turn to Chrome browser if I want to watch YouTube videos

not working

Either the notice of Not playing HTML5 OR double sound efffect.

It doesn't work for me.

No funiona, no consigo ver los videos html5 de Youtube
