As of the time a scroll down of the page is done while the Flash Player is playing the video will then freeze and all video controls are disabled but the audio will continue (sometimes just a small amount of page scroll will cause this problem other times a larger amount of scrolling is necessary). It's like the video is locked at that point when the page is scrolled but sound continues to play.
Testing in other browsers (FF, Chrome, IE, Opera etc) I can scroll as much as I want and the video continues to play fine as has been the case with Pale Moon as well in the very recent past.
I am able to scroll up or down as much as I want in other browsers and the video part of the Flash Player will continue to work and the video controls remain accessible as well.
It appears this issue with Pale Moon is relatively new because just in the past week or so this problem did not occur and the last time Pale Moon was updated in my case was on the date of 9/28/16 for the release of v26.5, so it seems to me the issue may not be directly related specifically to the most recent Pale Moon build but something is now uniquely impacting Pale Moon.
The next video will work again that starts up after the video that is locked, but same problem with scrolling the page will occur.
Discovered an important point before posting: If I leave the page (click on a different tab) and then return to the video (click on the video tab again) then the video will be working again and video controls are restored as well. (scrolling the page however causes the same issue once again)

Flash Player info: Question: Is anyone else getting this same problem for PM v26.5?
(after spending an hour with same results I'll just avoid scrolling on this site when playing videos 
)
