I have been using FF for many years with Windows 10, every time I launch FF it starts up, brings me to my start screen of favorites, and then shows itself still downloading on the top taskbar pane, but everything is already loaded on screen. The cursor will then not change to the hand pointer to follow links on screen. the bookmarks open to blank or unresponsive pages. Closing and reopening FF gives the error message that processes are still running and do I want to open a new window with FF, but that is unresponsive as well. 

Dear FF/Mozella staff, I have been using FF for many years with Windows 10, every time I launch FF it starts up, brings me to my start screen of favorites, and then shows itself still downloading on the top taskbar pane, but everything is already loaded on screen. The cursor will then not change to the hand pointer to follow links on screen. the bookmarks open to blank or unresponsive pages. Closing and reopening FF gives the error message that processes are still running and do I want to open a new window with FF, but that is unresponsive as well. back to internet explorer, Thanks for that
