Features & Capabilities

CurrencySwap converts prices directly on the page not in a popup, not in a separate tab. Just your currency, right where the price was.

How it works

Pick your target currency, choose which ones to detect, and toggle it on. Every price on the page updates instantly. The original value stays visible in brackets so you never lose context.

CurrencySwap goes beyond basic symbol matching:

Symbols — $, £, €, ¥, 円, ₩, ₹ and more
ISO codes — USD, GBP, EUR, JPY and 40+ others
Written names — yen, dollars, pounds, euros, baht, won, quid, and 70+ variations including qualified names like "japanese yen" or "swiss francs"
Flexible spacing — handles both "20,980yen" and "20,980 yen"

Features

Converts in-place on the page, not in a separate window
Works alongside browser translation extensions
Stays active as you navigate between pages
Handles dynamically loaded content (infinite scroll, AJAX, SPAs)
Clean restore when toggled off — no leftover markup

Privacy

No data is collected
No tracking.
Nothing about you or your browsing leaves the extension.

The only network request is to ExchangeRate-API to fetch public exchange rates.

Is CurrencySwap Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

CurrencySwap requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

CurrencySwap is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
