I used Mozilla Firefox on Win7 x 64.
So I note over at Github that this is now in version 1.0. Is it out of beta? Your other 2 signin plugins work like a dream so can't wait to get this one rocking.
It should be, yes. The fact is that I haven't created a documentation for it yet, so although the plugin is already available on GitHub, you don't know how to run it. Honestly, I think it's quite stable to be released, but I won't have time in the next 2 weeks to dedicate myself to it.
