I do not have Keepa but I do have uBO and I see this as well:

Have a look at #186, #80 and #218 and other issues, this has already been addressed. You can ignore this kind of warnings.

I have encountered a (possibly) related issue: when writing comments on blogs the comment will not be displayed after post even when I have temporarily allowed everything, including off-site scripts. Even when ScriptSafe is disabled, reloading the page and repeating the comment post action does not work if a cookie is used to confirm/display a comment which must be approved by a moderator. I suspect that Chrome's caching behaviour may be part of the problem.
