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.
