This Addon‘s perfect. But it seems to be not working in Firefox 19 and 20. Is there any update?

I'm sorry for my bad English. I've found that "issue" page but I just can't understand. So, I edit this review.
The problem is: It looks fine but does not perform Synchronization. Yes, it only shows some UI in FF 19 and 20.

We found the issue and posted a fix. It's available from the versions page, while it's still under review (https://addons.mozilla.org/en-US/addon/reqpolsync/versions/).
