When I am in FireFox, and I mouse over any area that would normally allow me to do something, like select a tab, close a tab, or even fill text into this details box, a circular "block" symbol appears and prevents me from entering or doing anything. I have scanned all of the installed programs in the Control Panel and removed anything suspicious and reviewed addons and the like in FireFox, all to no avail. BTW, this problem does NOT occur while in Google Chrome, but I much prefer FireFox. Help!!!

Note that your System Details List shows multiple Flash plugins.

  1. Shockwave Flash 11.9 r900
  2. Shockwave Flash 11.8 r800

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove all (older) version(s) of the plugin (NPSWF32) and (re)install the latest Flash player.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...
