Hi, I'm using 0penlayers and with this online example : https://openlayers.org/en/latest/examples/export-map.html when clicking "Download PNG" button I get the following message in Firefox console : "Blocked https://openlayers.org/en/latest/examples/export-map.html from extracting canvas data because no user input was detected." And the image downloaded is incorrect. I have no Firefox user message asking for permission to canvas access. I'm using Firefox 107.0.1 (64 bits) Mozilla Firefox Snap for Ubuntu canonical-002-1.0

With Firefox on windows or android the example is working fine. On the example web page there is the javascript code using the canvas.

Bye !

Pierre.
