Crash on Firefox 72 on Mac (script is "blocked from extracting canvas data") about leaflet.heat HOT 7 OPEN

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.

from leaflet.heat.

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)

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

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

from leaflet.heat.

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

from leaflet.heat.

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.
