To disable Preview from Mozilla Firefox, you may open the firefox and enter “about:config” from the address bar. Then just proceed with the button of “I’ll be becareful, I promise!”. In the filter bar, enter browser.taskbar.previews, and set the value to false for browser.taskbar.previews.enable.
From your Windows, go to the directory of “C:\Users\username\AppData\Local\Google\Chrome\Application\“, go to the properties of chrome.exe, move to Compatible tab and set the compatibility mode. You may choose to have Windows Vista mode(any mode from Windows Vista will do).
