Thanks to a heads-up from [Paul](http://onlinejournalismblog.com/?ref=onemanandhisblog.com), I’ve just discovered that [coComment](http://www.cocomment.com/?ref=onemanandhisblog.com) blocks commenting on this blog. People using the [coComment Firefox extension](http://www.cocomment.com/tools/capture?ref=onemanandhisblog.com) will not be able to comment here ~~at all~~ if they’re using any form of sign-in to the blog (eg OpenID), getting back an “invalid request” message. This is a coComment bug, not one with Movable Type.

~~coComment has been aware of this issue for [nearly a year](http://www.cocomment.com/forum/viewtopic.php?id=746&ref=onemanandhisblog.com), and has yet to resolve it~~ ([see below](http://www.onemanandhisblog.com/archives/2008/09/cocomment%5Fusers%5Fa%5Fwarning.html?ref=onemanandhisblog.com#comment-234722)). My apologies to coComment users – there is nothing I can do about this.

**Update:** Here are the specific circumstances where coComment causes commenting to fail

- **Browser**: Firefox 3.01
- **Platform**: Windows XP SP3 and Mac OSX 10.5.5
- **Extension**: coComment Firefox Extension installed

When I comment with the extension disabled it works fine. I enable the extension, the commenting fails. I disable it again, commenting works. I’ve tested this on several different computers, with different OSes, as mentioned above. It replicates simply and perfectly

**Update 2:** More information – the failure seems to occur specifically when commenting using a login – either Movable Type native or OpenID in its various flavours. Non signed-in commenters should be fine.

\*\*Update 3: \*\*This has been successfully [resolved by coComment](http://www.onemanandhisblog.com/archives/2008/09/cocomment%5Fusers%5Fa%5Fwarning.html?ref=onemanandhisblog.com#comment-234723).
