Settings
In about:jetpack > Installed Features you can click on the settings link after JetQRCode item to set your preference:
- Shorten: JetQRCode can shorten the URL with is.gd (or TinyURL.com) first, then use the shortened URL to generate QRCode. It's good for decoder in your mobile device, but could be slow and have privacy issue1. If you wanna try it, you can enable it here.
- Output encoding: The encoding of messages in QRCode. The default is UTF-8, you might want to switch to Shift_JIS if you have a Japanese mobile phone.
- Image size: You can decide how big the QRCode image is, from 150x150 to 500x500.
Known issues
- The QRCode is actually generated by Google Chart API — again we have privacy issue2. Check Google's Privacy Policy, if you don't like it please don't use this extension.
- [bug] Should not add a menuitem when nothing selected.
- [bug] Can't create QRCodes for text selected in form elements.
