Datalogic scanners are normally sending CTRL+J when reading a line feed (LF) character and ENTER when reading carriage return (CR).
That's not cool if you use the scanner with Linux or Android since QR codes mostly use Unix line endings (LF only) when they contain line breaks.

You can work around by using the character replacement feature of these scanners.

Use the Datalogic online tool to create a config code: https://aladdin.datalogic.com/

1. Select your scanner
2. Go to "Data Format" -> "Character Replacement"
3. Enter "0A0D" for "Character Conversion" to tell the scanner to replace LF (hex "0A") with CR (hex "0D")

In some constellations, Firefox shows context menus at a complete different position on the screen, especially when the window was dragged to the left or right screen side so that it snaps in and fills 50% of the screen (known as "Aero Snap" on Windows).

Fix:
1. Right-click on the title bar -> "Customize Toolbar..."
2. On the bottom, uncheck the checkbox "Title Bar"

That's it! Without the title bar, all menus and popups are shown on the correct position!
