This is the second time I have put this forward. Using Firefox on Windows 10, I am unable to view yahoo emails. I get a white screen with a black bar across the top. Yahoo will tell me I have "5 unread messages". If I go into Yahoo using Edge, I can view the emails (which is why I think it must be a Firefox problem, but I may be mistaken. The one response was to empty the cache and such, which I have done and it doesn't help. Does Firefox not empty its cache each time I leave the site? If this is a Firefox/Yahoo interactive problem, I apologize - it may be something about Yahoo. I have wandered all over their support sections though, without finding a potential solution. Thanks for any support/suggestions you can make.
