Hi, you can try turning off Mixed Content - Mixed content blocking in Firefox

You could also try Ctrl+F5 to refresh the cache. Or even try deleting ALL references to Yahoo. To do that, open the 3-bar menu, choose History (looks like a clock), then click the Show All History link at the bottom of the list to open the Library window. Search for the website you want to clear by typing its name in the Search History field in the top-right corner, then press Enter. Now in the search results, right-click on the site you want to remove, and select Forget About This Site. (Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed). Give it a minute to complete the deletion then try the site (not from an old bookmark) again. More - Delete browsing, search and download history on Firefox

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

thanks for the tips, I did all of them and it's possibly a little better but not enough to alleviate the frustration. Any other ideas?, thanks
