Almost pefect! Rated 4 out of 5 stars
This is EXACTLY what I was looking for. Until now, I've been copying the URL, opening a QR code converter page, pasting, then finally getting a QR Code I could use with my iPad or iPhone. Now it's barely one motion and up pops a QR Code!!!
My only complaint is that I need to have my Add-On bar open all the time. I never needed to before because I would just add the Add-on next to the URL and Search fields at the top of my browser.
I really hope you'll add that feature soon. Then it'll be a 5 star add-on!
Toolbar icon added
After a long delay, I've now added a toolbar icon to the extension. Hopefully the new version will be available for you to install soon, after it gets approved.
