What do I do with "We're sorry, but we were unable to complete your request. The following errors were found: Input error: Cookie value is null for FormRestoration.", and I checked my cookie settings?

Firefox

Last week I had no problem posting to the blog at http://hcologne.blogspot.com/ but I might have updated Firefox since then. Tonight I keep getting the message: "We're sorry, but we were unable to complete your request. The following errors were found: Input error: Cookie value is null for FormRestoration". I checked my cookie settings in tools-options-privacy-use custom settings, but it didn't help.
