Good, saves time and clicks, adds an additional layer of safety

Any chance to make it available for Thunderbird as well?

Would you all add an option to the right click menu to be able to search a string on VirusTotal? I copy a lot of domains to my clipboard and then search them on VT. It would be slick to be able to just send the domain name to VT

Great to see this finally updated. I like the new features, but the pause download when sending to VirusTotal doesn't work. On every attempt I tried the download would cancel, and not resume. That's the only gripe I have right now, so I turned that option off until an update fixes it hopefully.
