I am able open yahoo mail in my firefox browser, but none of the buttons are working. i cannot select a message by clicking the checkbox to the left of the message that is displayed in my inbox. if i select the message by clicking on the message, instead of being able to view it in the pane below my list of inbox messages, it appears in a new window. in that new window, no buttons are working. cannot delete, forward, reply, or use the back button to get back to my inbox. also unable to click on the calendar icon and see my calendar or click on the contacts icon to see my contacts. yahoo mail works fine in both edge and chrome browsers only having this problem in firefox.
