For a while now, I’ve been unable to post comments at *.blogspot.com blogs. Even anonymous comments, in blogs that allow them. Alas, when writing a comment and clicking the ‘Submit’ button, the page was just reloaded, and no trace of my comment was left behind. Weird is an understatement. Puzzled as I was, now I have discovered the reason: unlike *.wordpress.com blogs, to post a comment, any kind of comment, at blogger, you have to allow third party cookies! Yep, to comment you must open yourself to the possibility of “anonymous” surveillance (even more than what you are already exposed for just using the internet). Luckily, there’s an easy fix (if you’re a Firefox user, that is): install the Cookie Monster addon. Then disable third party cookies globally (Edit -> Preferences -> Privacy), and go submit a comment. It’ll reload the page, but the addon icon in FF’s bottom bar will tell you that the page tried to set a third party cookie. Allow it to do this always. This way, you disable third party cookies by default, while still allowing it for those sites that require it, viz. blogger. And presto, problem solved!
