Flash Plugin doesn't show up fullscreen

[hammadakbar]

Installed Trusty Tahr Demo ver. using official image(shows up as 13.10 in info)
initially it did work one out of 10 times but nothing seems to make it function now.. sometimes the fullscreen would show but quickly loose focus and return to the firefox window with frozen flash object.. the flash object would unfreeze once i cause it to loose focus(upper left corner) or if i switch tabs and return to flash object tab.

Things i've tried:
Updating firefox 25 to v 28
reinstalling flash from soft.center/source(11.202.336)

This bug is reproducible on my machine
It is triggered by any flash video that can be maximized to fullscreen, the pattern is this: The first time i click for fullscreen, it works, the second time; the fullscreen click freezes the flash object and fullscreen doesn't work after that. Sometimes the freeze would unfreeze if i switch tabs or switch focus to another wiindow and back.. the fullscreen still doesn't work after that.

Also; i'm not sure if i should've filed this under "flashplugin-installer" i thought because the same package used to work fine on 12.04, something in Trusty Tahr must've changed to cause it to behave this way.

results for:
apport-collect 1282569
sudo apport-collect 1282569

Package adobe-flashplugin not installed and no hook available, ignoring
then a window shows up telling me "No additional information collected"
