UPDATE: You fixed it!

If it helps, I tested the previous version disabling every single addon and it still didn´t work on amazon.com, mobile.de, elpais.com and other hugely popular sites. I´m using FF 58.0.2 x64 and it works now for every site I´ve encountered so far, including the aforementioned.

And pretty great about the icon BTW, it´s much faster than right click+scroll down menu+click QuickCut, and therefore an actual improvement over the good'ol DeskCut.

Thanks, Mr. Developer!

Promising, but utterly unreliable.

Like someone else said before, it doesn´t work on Amazon, and it doesn´t work either on MANY other sites, for whatever reason, not giving you an error message or anything. It just doesn´t to anything at all.

As such, you just cannot TRUST it, you have to monitor your download icon or something like that to make sure you have actually saved something, or you risk losing it, so it´s not only unreliable, but actually stressful.

Anyway, I just disabled it until the next update. And if it ever works properly, I´ll update my rating, of course.

Thanks.
