Feature Request Rated 4 out of 5 stars
This is a very good extension, and thank you for your good work.
The "currency converter" toolbar button was a bit difficult to find in Firefox's customise toolbar list, but once I found it, this extension worked almost exactly how I needed it to.
One thing, tho:
It would be great to have a way to set the default behaviour of the currency converter to enabled/disabled, and to have a customisable list of exceptions to this setting.
This would allow you to enable the functionality for a specified list of sites, so that it works effortlessly for sites that you use all the time and require the converter functionlity to be enabled. I hope you understand what I mean.
If this functionality is added, I would certainly give this extention 5 rather than 4 stars.
Best of luck Hal
