Any suggestion on what QR code reader to use
with firefox on FC39 or FC40?

I haven't seen any QR code scanners with firefox, the only method I've 
seen or used is to scan the QR code with a scanner on my mobile phone. 
Does that work or do you need it to be done from within firefox?

regards,
Steve

I only have a dumb phone.
I want to read a code that comes to me via web page.
My usual browser is firefox.

If CLI is okay, save an image (take a screenshot if needed) and use
zbarimg from the zbar package.

Thanks.  I wanted a recommendation because the mozilla
site made a point of not recommending any  of them.

Maybe because:

You want tools that allow you to see URL's as text (and ideally checking
for known compromised sites) before
opening them in a browser.

I'm kind of curious what websites give you a QR code to scan, but don't
give you any link to click on.  Have you seen if the QR image is a
normal link, too?

I really hate this cross-contamination of technology.  I'm on a website
on my computer, why would I want to do half the task there, half on the
phone?  It really only makes sense as a "scan our phone number" if
you're too lazy to type it in.  Or worse, you're browsing the site on
the phone - then what am I going to aim at the QR code?  Or businesses
that make it impossible to email them - they'll send you an un-
repliable email.  Likewise with un-repliable SMSs.

I've seen sites do it during multifactor authentication scheme
enrollment. I believe I encountered it on one of Google properties
several years ago. Google even did something to ensure the QR code was
unscannable once printed. If you wanted to use the QR code on two
devices, you had to have both devices ready at the time of enrollment.

The WhatsApp web interface needs you to scan a QR code using the phone
where you have WhatsApp installed. That makes sense to me.
