Dear Sir/Madam, The IOS version of Firefox (both iPhone and iPad) cannot receive tab pushed from all other devices (including pushed from Windows and IOS). I am sure that the Firefox on IOS devices is logged in and the notification of the IOS is on. This problem happened a few months ago which it was fine in the past. I tried to logout the Firefox account and re-login. Also tried to delete the IOS apps and install again. But all the methods I tried cannot solve the problem. Thanks Calvin
