Usual windows 7 opening and closing of windows are not working with my updated Firefox 16.0.1
My Windows 7 automatically updated recently and so did Firefox. Now, with all other Windows applications including Internet Explorer, I can open a new window by right-clicking on the icon in the taskbar (showing there because the application is open), and when I right click, it gives me the option to close all windows. With Firefox, this also used to be the case, but since the update, when I right -click on the open Firefox in the taskbar, nothing happens. And when I tried to "pin" Firefox to the taskbar, even then, I cannot close all open windows just by right-clicking, and it is a longer procedure to open a new Firefox window. Suggestions would be greatly appreciated....
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 or otherwise make changes.
