I am trying for days to get my Yahoo! email to stay signed in on my desktop using Firefox. It has been fine for years, but last week I had to clear cookies and history to solve a completely different problem and now I have this problem instead. I have read articles, searched the web, and I am trying to find "options, set yahoo as my email" (or something like that I read) but I cannot find it in yahoo OR Firefox. please Help! thanks in advance, but hurry.
