Using Alt + tab on an open Firefox browser window, minimizes the window and is completely inaccessible from the taskbar, as well as the task manager. I can only view options to end the task and other standard options n the Firefox processes which are running (in the background). For example, if audio is playing from a tab in the current Firefox session, and I alt tab it, there is no way to restore this minimized Firefox window. There is also no visual highlight on the Firefox icon in the taskbar that, one window is currently in session. it looks like there are no open Firefox windows. Shift right clicking on the Firefox icon only shows the standard menu (as in the case where you have not yet opened Firefox), instead of showing options such as maximize, restore etc. Since there is no way to return to my session which is still active, I have to go to task manager, end all Firefox tasks and reopen the application. Please help!
