Comodo Dragon doesn't play videos from instagram.com

I’m not able to play videos from instagram.com. Whenever I click the play icon on any video on instagram.com , nothing happens.
Using the latest Comodo Dragon 45.6.11.385 with ublock origin and comodo media grabber plugins, on Win 8.1 64bit and latest adobe flash player for firefox and chrome is installed.
UAC status disabled, installed in "C:\Program Files (x86)\Comodo\Dragon" folder, User privileges administrator, latest Google chrome stable is installed (46.0.2490.86 m) and I don’t have this issue on chrome browser.
Can anyone verify this issue on their pc’s with similar specs?
Thanks

Please try updating to Dragon v46. It got released today: https://forums.comodo.com/news-announcements-feedback-cd/comodo-dragon-46-is-now-available-for-download-t113775.0.html .
