Crash on Firefox 72 on Mac (script is "blocked from extracting canvas data")

Console logs:

What's the complete platform (OS and firefox version) and steps needed to reproduce?

[kinh-nguyen]

Open this plugin's demo with Firefox on Mac Catalina.

Pal, I hate to extract information bit by bit:

• I asked for the firefox version, so I'm asking about it again
• Is it just a warning on the console?
• What is the degree of functionality affected: none, some, or all? Does the heatmap work at all, partially, or well?

At this point I feel obliged to point you towards http://www.chiark.greenend.org.uk/~sgtatham/bugs.html

[kinh-nguyen]

• Firefox 72.0.2 (64-bit)
• just a warning that it blocked the script
• Heatmap does not work, even the map itself turn blank

[IvanSanchez]

Can't reproduce on Firefox 72 on Debian linux. This is not caused by Firefox 72's new tracking protection features.

Still, I don't have a Mac around, so I'll need to wait for somebody else to reproduce this in order to confirm.

If it's any help, I found that it doesn't seem to happen on my Firefox 72.0.2 on macOS Catalina. If you replace http:// with https:// however then it prints errors about mixed active content and the map fails to load but I suppose that's a separate issue.

this thread popped up when I searched on
'Blocked digid.nl from extracting canvas data because no user input was detected.''

taken from the console warning:
'Blocked https://digid.nl/inloggen_app_qr?utf8=%E2%9C%93&app_verification_code%5Bverification_code%5D=SMJX&button= from extracting canvas data because no user input was detected.'

that is in Nightly: 87.0a1 (2021-02-22) (64-bits) (Ubuntu 20.10)

It blocks me from logging via QR-code on a Dutch government site. (QR code is not displayed)
