Hello, I have tried Googling this and checking the Youtube forums (or whatever they are) and I couldn't find very much at all. Anyway the problem is ever since I updated Flash Player maybe 3 or 4 weeks ago (this is before two additional updates that I hoped would fix this problem) I have a problem with the videos on Youtube when scrolling with the mouse or keyboard and even the scroll bar. What happens is, if the video itself doesn't fill the entire player size and has black margins on either side then the video gets all messed up. It's difficult to explain and that's probably why I have had a hard time finding any results using Google. Fortunately I have found one result that show this problem and I am certainly not the only one experiencing it. It is a video and it's on Youtube... Firefox Youtube mouse scrolling issue. If anyone else here is experiencing this or if it has been mentioned before and someone knows how to sort it I'd appreciate it. Thanks.
have you tried clearing cache and cookies ? or reinstalling flash ? are you sure its set to flash btw, since it sometimes sets it to html 5 it seems. im using this addon btw *yousabletubefix* http://userscripts.org/scripts/show/13333 enables you to adjust youtube settings. needs the greasemonkey addon https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/
A new update has been released with the following notes; http://www.filehippo.com/download_flashplayer_firefox/
Thanks for the replies. I always clear my cookies and cache along with everything else upon exit, well technically the cookies are deleted at start up expect for those that are protected (Cookie Culler). I am pretty sure I am using Adobe Flash Player to play the videos, I don't see how else it wouldn't use it plus the issue started after the update (as well as two instances of Flash Player running in the Task Manager which I have never seen before, anyone else get this?). I tried updating the Flash Player as suggested by Pill Monster, no change plus I did reinstall the entire thing after the issue started. I wanted to go back to the previous version but I wasn't sure how or what the version was exactly. I'll try and see if I can do it but I really shouldn't have to. In the video I linked to there is a comment that mentions problems with making comments in Youtube, I am also experiencing this issue.
