ABPlus Makes Fullscreen Button Disappear on Youtube

[bjabp]

I have recently run into an odd problem.

Occasionally, the Fullscreen button on Youtube videos is missing. Only the regular and cinema, or halfscreen buttons show up. The fullscreen button comes back when I disable Adblock Plus. YET I've had Adblock Plus turned on while watching many Youtube videos in the past without issue. The fullscreen button was always there.

I've had this issue in the past, but forget what I did to rectify it (apart from disabling Adblock Plus on Youtube). I've tried rebooting my computer a couple of times to no avail. The only thing that seems to restore the fullscreen Youtube button is disabling Adblock Plus.

Any ideas?
