Cannot read image in a browser, always asking to read the webcam which I don't have.. You need to do a right click > Copy Image, then AGAIN a right click to launch that extension then a Ctrl+V to put an image from the clipboard from the browser, to paste it in the popup ..

Love it, probably the most comfortable extension on the whole market. The only nuance is that the window opens in a separate tab, which I have to close after scanning. Is it possible to make it a pop-up that disappears automatically? That would be AMAZING!
