Same with me. Been that way for months.
On 4 different computers I regularly use.
No 1. Toshiba I5 with Windows 8.1 & Firefox
No 2. Lenevo with Windows 10 & Firefox (not used much)
No 3. Old desk top with Windows XP & Firefox (like an old straight 8, just keeps on going doing the job intended)
No 3. Work DELL laptop 32 bit with Windows7? professional or something & Chrome and MS Explorer (FF will not run due to corporate IT) (a dog of a machine)
