When I mouse over a tab active, a circular symbol "block" appears and I can't close the tab or by clicking on

When I'm in FireFox and I smile any area that normally would allow me to perform an operation, select a tab, close a tab or fill out the text in this area of details, a circular 'block' symbol appears and keeps me enter or do whatever it is. I scanned all the programs installed in the control panel and removed something suspicious and reviewed addons and other in FireFox, all anything will do. BTW, this problem does NOT occur in Google Chrome, but I prefer FireFox. Help!
