Doesnt work at all. I tried it to convert EUR to CZK on many sites and it calcullates total nonsense values.

No matter how many times I check the settings to ensure that "Convert pages automatically on load" is unchecked, pages continue to automatically convert, slowing my browser loading time to an absolute crawl. I only need conversion for a few websites, not my entire browsing experience. Uninstalling.

Really slowed down page loads, and made pages with javascript updates run really slow... I'd love an extension that only activates when you highlight a text, and then shows result in a popup, like in Opera.
