Rated 5 out of 5 stars

Mike Kraft asked me to try re-installing 1.0.0.10. I did this and it worked fine. As I told Mike, the next time a new program doesn't work I'll try re-installing. It's a standard procedure and I was careless in not trying it.

This review is for a previous version of the add-on (1.0.0.10). 

So far everyone who has told me that 1.0.0.10 doesn't log in, had it start working by itself when I asked them for debugging data.

If you still can't log in, follow the steps at http://ymnotifier.mozdev.org/bugs.html and send me the debug data so I can figure out why.
