This relates to my Macbook Air (2010) running on OSX10.10.2.T Three days ago, I ok'd a Firefox refresh and when I did - my Yahoo Mail! account dropped all of its icons on the mail pages. There are programming symbols there and when I place the cursor over them, the function is defined and works but this is really slowing me down. Is this a Firefox issue or a Yahoo issue? I have been trying to get Yahoo help through their answer community but no luck there. I am at best an advanced novice - I do not program at all and primarily reolved my problems through help desks or community help.
