I have Shockwave Flash set to ask to activate and I have media.autoplay set to false and they still keep playing.

If you aren't getting asked to approve Flash on the site, then the site probably isn't using Flash. If you want to approve some Flash videos and not others, you need an add-on to extend the feature, for example:

The media.autoplay.enabled preference "works" for videos that use the native HTML5 video player. The reason I put "works" in quotes is that many sites have discovered a trivial workaround: use a script to send a play command to the media to start it. Since it was stopped initially, that is not considered to be an autoplay.

It looks like Firefox 41 will finally block that trick; the code change was checked in on June 5th. Sometimes code changes can be moved up to a closer release, but I don't know whether that is possible in this case (it's definitely too late for Firefox 39). Anyway, this should be solved in less than 4 months...

Until then, as a workaround, you could try an extension. I looked at a few on the Add-ons site and the reviews on their effectiveness was very mixed, so at this point, I don't have any recommendations. If it's really maddening, you could take a look there.
