I have used Firefox on my PC for ever (10-15 years). Yahoo was set to be my home page so I can get to my email. Starting 5-6 days ago when I click Mozilla Firefox on my task bar it opens a white (blank) page, no yahoo (but it shows yahoo.com in the address bar). I can go to my book marks and got them or type in a URL and go there OK. But, to see my mail I have to open Google Chrome to get to yahoo and log in. If I'm on Firefox and get the blank screen, then go to another URL from my bookmarks then type in yahoo.com it goes back to a blank screen that shows https://www.yahoo.com/ in the address.
