Unnecessarily restricted without the paid premium API access, that said, VT4Browsers is very helpful and seems to be well built with a minimal/acceptable number of problems and errors. Having a VirusTotal free account is recommended.

Please just make this available on Android, I'll change this to a 5 star immediately

Edit: it happened. Send to VirusTotal prompt failed when I tried to scan an epub file. I donwloaded then sent to Virustotal from my PC and there was a detection. It better be a false positive. I can no longer trust VirusTotal to protect my computer

It was a life saver when it worked but now it simply cancels my download half the time and doesn't even try to scan the file

Some months ago it would turn out upon inspection that I pressed "download" in a private window but the link to the scan results only appeared if I opened a regular window. Inconvenient but technically still worked

Lately it doesn't show the scan prompt or the link in any window I open, in 50% of the cases. At least it can scan links

And yes, I can still scan the file after downloading it but I'd rather not risk my computer's health (Edit: lol should haave listened to myself. Never again)

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

Link introspection (when API key is added) breaks comments on Amazon wishlist entries by inserting HTML in comment area. No way to retroactively upload file, nor see upload history. VT file upload auth prompts are considered to originate from visited site, and thus can be subject to "Don't allow from this site" option on per-site basis, reducing security. Need instead to originate from extension.

Neat addon for faster checking links and downloads with VT. Sadly there is currently a bug that breaks some websites when this addon is installed (for ex.: paypal sign-in not working). Also using this addon besides script-blocking addons (for ex.: uBO) breaks some functions of VT4Browsers (for ex.: sidebar). If those things get fixed i gladly will use this addon again but for now i uninstalled it because of the problems described above.

Any chance to make it available for Thunderbird as well?

They should create new vendor agnostic URN:SHA-256: protocol or similar instead of search selected hash and 5-6 actions per each hash... 1-3 clicks is clearly better than 5-6...

Works effectively and efficiently; as it should!

Used this add-on for many years. But the last version (4.0.2) breaks the CSRF check on my "postfixadmin" (3.3.11) site. After sending the login credentials I get "Invalid token! (CSRF check failed)". As soon as I disable VT4Browsers the login works again.
