If you're using the "new" Yahoo Mail display, hover your cursor over the "gear" icon in the upper right corner of the screen, choose "Settings". Once at the settings display, select "Basic" instead of "full featured", then click on "Save". Lots of folks are having similar issues with the new "improved" view at Yahoo Mail.
Hope this helps.

For the last few weekss my yahoo mail has been taking a longer and longer time to load. Sometimes it 'time out', and I got to start all over again, both in firefox and google chrome.
I am using a Dell Inspiron 15 laptop with os windows 8.1
I have run super antispyware C and Ccleaner to no avail. Situation seems to be getting worse.
Please help.
