Has not worked for several months Rated 1 out of 5 stars

This used to be excellent but I don't think it is supported any more. Hasn't worked for months. Constantly get error "Error in Blank Canvas Gmail Signatures: "
Currently Win7 FF 16.0.2 Blank Canvas Signatures for Gmail 1.18.6b (tried 1.17.3 but it did not work either.)
