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"

Excellent concept, but the core function of the add-on no longer works on current versions of Firefox Dev.

Every function doesn't work (exept the scan of downloaded files), the result is always an "Error 404" page.
(I refer to "Scan selected link" and "Scan current page" functions)
