Testato soltanto su Furaffinity, nel mio caso e da impazzire, chiede in contemporanea dove salvare i file al posto di farlo silenziosamente, tanto vale fare salva uno ad uno. ( 2 stelle anche troppo in attesa di spiegazione o fix )
Eng:
I have try on Furaffinity and the software prompt at EVERY FILE the Save Request Directory in Windows, and it lag the sistem because the opened system pop-up, why is not automated in sudden mode ?. (72 file...72 Pop-up ask where save file !)
Note to Reply:
Yes, i have these option on "Firefox" but only your Add-On make to my these problem, the other make operation in Sudden Mode, even if the "Firefox" is set to "Always Ask", i think there is a way to "Bypass the default option".

It's very light and you can easily check the photos you have already saved from the browser. You can reliably manage the items of your favorite artist. Recommend to you this addons.

Thanks for the great update.
Could you add database management capabilities if possible? For example, delete the database of specified artists at once. Thank you.
