I go to https://www.google.com and click Sign In, that takes me to https://accounts.google.com/CookieMismatch and the message displays:

Now, cookies ARE enabled, I DID clear the cache, I DID delete all the Google-related cookies, and Firefox's Options pages have no setting for privacy level that I can find. Also this problem does NOT occur in IE, so it's not McAfee Antivirus that's at fault.

I'd be so grateful if you could help!

Can you please try deleting all cookies on Firefox. Not all cookies related to Google will be labeled as Google related. Deleting all cookies will ensure that all of the corrupt cookies that Google is referring to will be deleted.

Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. Click the menu button New Fx Menu, choose History, and then "Clear Recent History...".
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the "Clear Now" button.

Further information can be found in the Delete browsing, search and download history on Firefox article.

Did this fix your problems?

It's totally unreasonable to ask users to delete all their cookies in Firefox or any browser. I have hundreds and depend on them. Trying to use Firefox starting with zero cookies would require me to search for information in many different places and would be very time-consuming. If there are Google-related cookies that are not identified as such in the list of cookies, and there is no way to identify all the Google-related cookies in order to delete them, and deleting them is the only way to solve this issue, then that is a major problem that Google and/or Mozilla should fix. Users should not be forced to adopt the brute-force workaround of deleting all their cookies.

There is a hidden page you can use to target most Google-specific cookies. Type or paste about:permissions in the address bar and press Enter. In the left column, Firefox will start building a list of all sites for which you have cookies, saved passwords, and various other data. Type google in the box above the list to filter it. More domains will appear over time. Then you can click each individual site in turn and check on the right side whether it has any cookies saved at the moment and whether it is blocked from saving cookies.

But as for your cache, you can just clear the whole thing. See: How to clear the Firefox cache. If you have a large hard drive, that could take a minute or two.
