I updated to FF 41.0 and Flash 19; Firefox no longers asks to activate Flash, despite me telling it to do so.

Previously I was prompted to Allow Flash to run in all cases; now it works only selectively (as on the Adobe website, but NOT on Youtube). This means that on Youtube (and many other sites), Flash runs without my allowing it to do so. BAD!

Chosen solution

For most Firefox users, YouTube no longer uses Flash and instead uses an HTML5-based video player. Here's how to check that:

Right-click the player, and you should get a short context menu. The last line of the short context menu should indicate whether it's the HTML5-based player or the Flash-based player. If you get Firefox's regular context menu, press and release the Alt key to clear that from in front of YouTube's menu.

HTML5? Here are a couple workarounds to regain control:

(1) Use the Flash Control extension to stop HTML5 video (and Flash video) from auto-playing

(2) Force YouTube to serve Flash instead of HTML5. There are a couple add-ons for that. Either of them will do, you don't need both:

I have heard these don't work for YouTube embedded on other sites.

Any improvement?

I'm fine with HTML 5 players; I just don't like Flash to work without my say so. Thanks!
