Currency Converter 作成者: sssilverhand

Currency Converter is a lightweight Firefox extension for checking fiat exchange rates without opening a separate website.

Features:

• Live fiat exchange rates from the Frankfurter API
• Selected currency rates against a chosen base currency
• USD-based history charts with hover values by date
• Instant multi-currency conversion
• English interface with Russian localization
• Dark and light themes
• Works on Firefox Desktop and Firefox for Android
• No account, no tracking, no ads, and no bundled dependencies

The extension stores preferences locally in Firefox and only contacts the Frankfurter API to load exchange-rate data.
