NC

WebExtension that automatically localizes prices on webpages to Nepalese Currency.

How the extension works

• The extension fetches latest currency exchange rate in the morning and caches it
• Converts all prices on webpages in foreign currency to equivalent NC.

For example, when you visit amazon.com, you'll get all prices in $X replaced with Rs. XXX.
