it just doesn't work. It's just too complicated. Tried this, tried that, free version, paid - it would just never work, always something new coming up. Not mature yet.

I had high hopes for this but entering email addresses by hand (instead of them popping up as they do in Gmail) was an issue, complicated by the email address always showing one less letter than I actually typed. That was quite annoying. ***UPDATE: This aspect suddenly started working properly after exiting my browser and restarting it, and logging in to Chrome again. *** I then attempted to send an email from within the extension, and it warned me that it would be sent unencrypted and asked me if I wanted to continue. I chose to continue but it then failed telling me that the recipient wasn't secure (diff wording). So it could not even send an email out insecurely. This has proven to be frustrating and a waste of my time. Too bad.

This is a great start. Just playing with it for a bit and I was able to send smime encrypted between my work and gmail email. Needed to figure out how to add my work smime cert as a trusted endpoint. I see I have a fossa smime cert in my windows key store. I will see what happens later when trying to setup on a different computer. I suppose I could backup and import my fossa smime cert. Great Job. This is pretty good. I don't think there is much out there like this. Keep up the great work!

Did not work. Perhaps because I was using gmail to read emails of different account? idk. Regardless even after installing smime.p7m is still attached and I can't view even after installing the extension.

Nice start, but three-month certs and 100KB max attachment size doesn't cut it, nor does the Fossa window closing itself if you type your passphrase wrong even one time. I look forward to giving this 5 stars after it's out of beta and such issues are ironed out. I'm impressed by the seamless integration.

Is there a way to make this extension work in Opera?

Finally a S/MIME solution for Gmail in Chrome! I am looking forward to add the possibility to use own certificates! Further, I couldn't find a way to verify signatures from Emails I receive... Keep on with your work, there are many people waiting for it!
