Firefox Sync

P.S. I don't use it because I don't like cloud.

EDIT: You use Opera. Then, instead of Mobile Barcoder extension:

Hey everyone, I just put together this trick for generating QR codes in Opera Desktop. Useful for sending links to your QR reading phone and such.

Anyway, just go to Menu > Settings > Preferences

Click on the Search tab and add a new search engine.

Then fill out the different fields accordingly:

Name: QR Generator
Keyword: qr
Address: http://qrcode.kaywa.com/img.php?s=8&d=%s

The rest should be blank and make sure "Use POST" is unchecked.

Save it, then just "search" a URL using the new entry in the search bar. A white page with your QR code in the middle should appear.
