Firefox Community Forum

I am trying to resolve an issue of not being able to receive any new emails on my Yahoo email acct. and they suggest clearing the cache on my browser which is firefox, but I am getting blocked from connecting to support.mozilla.org

I have read and tried all the previous discussions on this and they are no help. I have Delete cookies and site data when Firefox is closed checked, and I have a list of exceptions. I also have Clear history when Firefox closes with Cookies and site data checked. When I close or Exit Firefox, and then restart it, all the cookies that were there before are still there. If I Delete All Cookies, then it deletes my exceptions too. If I'm doing something wrong, then you are making it way too hard to do.

After many years with (up-to-date) Firefox as my browser, I have enjoyed being automatically signed in to Google. A few days ago, Google started requiring me to sign in for every new session. There is no issue with another person creating an issue. The problem seems to be Firefox will not save cookies and data. In Privacy and Security and in "Clear Data" the "cookies and site data" box is NOT checked since I do not want them deleted. The "cached web content" box IS checked because it can be deleted. When I click on "Clear" the "Clear Data" box disappears. When I open the box again, the "cookies and site data" box is again checked even though I had unchecked. The "cached web content" box is checked which is correct. There is no box labeled "save". My only choices are "cancel" or "delete". I have refreshed Firefox and deleted 3rd party apps. How can I make Firefox remember to save "cookies and data"? I do not want to have to sign in to Google every session.
