Yahoo keeps signing me out of mail

[slsl60]

I go to Yahoo mail (normally it automatically signs me in and opens to the mail) and once open at different time intervals it signs me out (even though I have checked the "keep me signed in for 2 weeks" box--a requirement that shouldn't be there in the first place) and I have to keep re-signing in over and over. Since this does not happen on IE and does with Firefox, it must be a Firefox problem. I have cleaned out the cache, checked to make sure that the "delete cookies on closing" box is unchecked, added Yahoo mail permissions, etc. Nothing works.

Any ideas?

You would only get logged out if you lose the Yahoo cookies.
If you do not use "Delete cookies and site data when Firefox is closed" and do not have extensions that deal with cookies then you might be clearing cookies otherwise, possibly via "Clear history when Firefox closes" or you might be using external cleanup software.

Thanks for the reply, but neither of those remedies apply here. It has to be some glitch within Firefox.

Tanks, but been there, done that. No help.
