Please remove the QR code scanner from the upper right corner of the URL bar. It is very easy to misclick because it is placed at the same location where the commonly used buttons are.
The QR code scanner is in these 2 locations:
1. Right-most button
2. Second button to the right
However, these 2 locations are also where the commonly used Tab and Menu buttons are. If you are used to clicking either buttons, chances are you have clicked the QR code scanner button by mistake.
Reasons why we should remove the QR scanner button:
1. I rarely scan QR codes. Honestly, I think I've scanned QR codes once every quarter. That doesn't warrant it to be so accessible.
2. It is prone to misclick because it uses the same location as the Tab and Menu buttons
3. There are other apps that scan QR codes. There are dedicated QR code scanner apps or it is included in the phone's camera app. It doesn't have to be done in Firefox.
Suggestion: Move the QR code scanner to the 3 dot menu where we can use it on demand.
