User Reviews
This extension is a little gem! In just a few clicks, I can have a fully encrypted message ready to be shared via email or messaging app. Knowing all encryption happens on my machine and that nothing is stored externally makes it my go-to for private communication. It's been updated recently and works perfectly with the latest Firefox. For a free tool with this level of privacy, it's an easy 5-star rating. More people should know about it!

I've been looking for a simple, trustworthy way to share sensitive information like passwords or private notes without relying on a third-party service. Crypto Sender is perfect. It does everything locally in my browser—no data goes to any server, which is a huge relief. The fact that it's open source gives me extra confidence in its security. For anyone serious about privacy, this is an essential Firefox add-on.

Is Crypto Sender 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.
Crypto Sender requires very minimum permissions.
Risk impact analysis details
- High Allows reading and modifying clipboard content, which can be sensitive, posing a moderate privacy risk.
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.
Crypto Sender is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
