User reviews

Users find this add-on useful for automatic currency conversion with a clean, simple interface. However, recurring issues include poor recognition and incorrect conversions, confusing or ignored settings, and performance slowdowns on pages with many prices. It also struggles with some currencies and specific websites, limiting reliability.

Pros

Converts currencies automatically on web pages, providing convenience.
Generally fast and simple to use when working properly.
Clean and useful interface for currency conversion.
Toggle features like hover + shift work effectively for some users.

Cons

Sometimes fails to recognize or incorrectly converts currency amounts, resulting in errors or strange outputs.
Settings and interface are confusing or difficult to use; some settings are ignored (e.g., disabling auto-convert or localization alerts).
Performance issues: slows down page loading significantly; high CPU usage on pages with multiple prices.
Does not support certain currencies or websites properly, leading to incomplete conversion.

Recent reviews

Works great, you can set it so that you simply hover over a price and you get the converted rate but I wish it had an option that allowed you to see multiple currencies at once, for example if I want to see the price in 3 currencies in one shot like AED, USD, and CAD

When it works, it works surprisingly well. When it doesn't work, it seems like it's 'dunce level'---not even recognizing obvious currency amounts, or worse, doing some strange thing where a perfectly clear currency amount is turned into some strange symbols/letters/numerals string of characters bearing no relationship to reality. It would be great if it could be fixed because it's very useful when it randomly works. NOTE: Someone else remarked that the interface/settings are difficult to figure out. No, they are actually virtually impossible to figure out. Bad, bad design!

Wonderful add-on. Works perfectly. I did however spend 10 minutes wondering what the hell was wrong with google sheets because my "$A$1" was being converted to "A0,96€". Heavily recommend whitelisting google spreadsheets as soon as you install the extension. Or make it a default setting?

Extension safety

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.

Universal Automatic Currency Converter requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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 Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on.
