Error "Failed to communicate with VirusTotal" now. This was a great 4 1/2 star extension while it worked, although I supplemented VT4Browsers with Winja.

Every time I open Firefox, it displays the welcome tab - annoying, unnecessary, inappropriate.

failed to communicate - does not work

I am given an error "Failed to communicate with VirusTotal" every single time.

It always display "Failed to communicate with VirusTotal".

Works great, nice add to installed AV

Love this browser extension! I use VT4 on a daily basis & feel much safer now. It's fast & easy to use. Be vigilant, my friends.

Terrible UX. Asks every time when uploading a file -- and after upload even, which makes no sense. Doesn't show scan result at all, only a link to it.
On the bright side, scans files themselves, too, rather than just URLs.

Awesome

Funciona, incluso puedes escanear las extensiones (application/x-xpinstall) clicando con el clic derecho sobre "+ Agregar a Firefox"

It works, you can even scan the extensions (application/x-xpinstall) by right clicking on "+ Add to Firefox"
