This topic does not fit anywhere else, so I am posting it here.
Today I was confronted with the following problem: I was sitting in front of my desktop PC, using my web browsr and came upon an address where I suddenly felt the need to send money to instantly (it was a betting site). My everyday money is on my Android phone, I wanted to make the payment from the Android wallet.
Unfortunately the address on that website did not display any QR-Code and so I had an idea: There must be a greasemonkey script to display QR-codes for any address on any website. I couldn't find anything usable on userscripts.org so I decided to make one myself. Here it is:
http://userscripts.org/scripts/show/168629When its installed and you hover above any BTC address then it will pop up a QR-code for that address. I have tested it on Qupzilla (this is a webkit browser so it might also run on Chrome) and I also tested it on Firefox. Please try it and give me some feedback.
