Duo Strength is a handy browser extension designed to enrich your Duolingo language learning by displaying each skill's strength directly on the Duolingo webpage. Inspired by data from duome.eu, it highlights skills that need improvement by listing them at the top of your tree, enabling quick access and efficient practice.

2025-10-15: After installing the extension, I didn't notice any changes to my profile pages on either duome.eu or duolingo.com. Is the extension no longer working? Duo Strength 2.1.0 (Nov 12, 2022) Mozilla Firefox 145.0b1 (64-bit)

Helpful info without having to go look yourself up at duome.eu/Username/Progress Note: DuoMe.eu is different in that it allows you to look up other people's language progress and their DuoLingo user stats. NOT the case with Duo Strength. DuoStrength only lets you see YOUR OWN INFO. I find this very useful, and it is supporting me as I practice "use it or lose it" strategies with multiple languages on DuoLingo. A nice, clean, non-distracting graphic interface, IMHO. It DOES take a minute to get used to seeing so much info on the otherwise-clean Duo web screen. Now I only notice it when I see someone NOT using Duo Strength!

Is Duo Strength 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.

Duo Strength requires a few sensitive permissions. 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 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.
