If Firefox gave you the following error message: Firefox could not install the file at https://addons.mozilla.org/******.xpi because:
Invalid file hash (possible download corruption) -261

This error message may be caused when Firefox is set disallow third party cookies. To accept the third party cookies: go to Tools -> Options -> Privacy -> tick 'Accept third party cookies'.

Thanks for answer. I am running Firefox on Mac (apple). How do I accept cookies from "third party" in Firefox for Mac?
