When I startup Firefox the new tab just spins and the screen is blank. It will spin until times out. However if I open another tab all is OK. If I open the second tab and open a website directly it works. If I open a website from a shortcut it will open most of the time but not every time. Also the program opens all websites very slowly, sometimes over 30 seconds. Download of content is also very slow. It is not the internet connection because Edge open very quickly. I have uninstalled and downloaded newest version and reinstalled. This did nothing to improve performance. I have also checked all settings possible. No solution, Please help. I do not want to start using Edge. Please Help! Thank You
