I cannot use cursor keys to adjust display etc. on sites such as Iplayer & youtube nor close windows using cursor keys, why?!?
I'm using Windows 7 32bit & cursor buttons in the corners of online windows will not work. I'm unable to close, move or adjust size of the windows. I'm also unable to skip forward through a video on youtube or Iplayer nor maximise or adjust the size of the window. I've blocked popups & tracking on initial setup of firefox & am using AdBlock plus though disabling that has'nt helped.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
