Exchange Rate Converter Rated 4 out of 5 stars

This add-on has two facilities, one much more feature rich than the other. I was looking for a replacement for the fantastic, very easy ECH which is no longer supported. I have no comment about the feature rich option. Installation puts a button automatically on the bottom status bar. To use the calculator, you click on the button and you are taken to a web page. IF you use 'no script', there is one field that has to be allowed. The quick calculator works instantly. Two things I was unhappy about: I would appreciate the option to put the button in the toolbar place of my choice. More importantly, I want the option (as I had with ECH) to create default choices for the 'from' and 'to' fields. The service defaults to USD to EUR and it takes 3 extra clicks to set it to GBP. For me this is a show stopper. If it isn't available in an update, I will sadly look for an alternative.

This review is for a previous version of the add-on (7-6-12.1-signed.1-signed).
