Rated 3 out of 5 stars

When it works, it's a great plugin, but it's very flaky for me (1.12.06b )

At first, it had a bad habit of "forgetting the signatures and I'd have to type them back in.

Lately, I just can't get it to show in GMail at all.

In general, I think this functionality is simply difficult to pull off with a browser plugin and it really needs to be a GMail Labs add-on

This review is for a previous version of the add-on (1.12.06).
