Excellent implementation of a light and fast dictionary lookup, but minus 1 star for lack of Android support.

I've been using this kind of extension from 2018-2019, starting from Google Chrome (Windows) and then switching to Firefox (Linux). Very useful, Love it very much and set it up whenever I re-install my OS. I wish something like this existed for other languages. Great! Recommend 10/10

Add-on works wonderful but when you click to top right icon after lookup, it doesnt forward to merriam webster, but rather to brittanica.

Is Merriam-Webster's Learner's Dictionary 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.

Merriam-Webster's Learner's Dictionary requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

Merriam-Webster's Learner's Dictionary has earned a fairly good reputation and likely can be trusted.
