Rated 4 out of 5 stars
This is a very good extension, and thank you for your good work, but there is one thing that annoys me about it.
I don't mind the fact that it cannot accurately detect whether every number in a web page is a currency, and therefore it often makes "convert" links out of the wrong numbers. However, as these links sometimes get in the way of a website's default functionality, I would like an easy way to disable and enable the currency converter functionality, most appropriately with a toolbar button, and/or to have an "allow" list of sites, so that I can set the convert currency functionality to disabled by default and enable only for a custom list of sites.
If this functionality is added, I would certainly give this exention 5 rather than 4 stars.
Best of luck
