It also happens when I try to upload images. Here I try to upload a profile picture but it becomes all jumbled.

Keep in mind this could be a website issue.

It's no problem, but here's a scratch games that uses images / sprites. https://scratch.mit.edu/projects/105500895/

The screenshot is from my end and from the exact same game.

I loaded the page. But: This project uses cloud data - a feature that is only available to signed in Scratchers.

If this is not enough, I can send a Gayzo of me loading in a page like this if needed.

This can happen if you block access to canvas like happens when "Resist Fingerprinting" is enabled.

Do you have enabled "Resist Fingerprinting" if you check this pref on the about:config page?

• about:config => privacy.resistFingerprinting => false
• https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting

You can open the about:config page via the location/address bar. If you get the warning page, you can click the "Accept the Risk and Continue" button.

This can happen if you block access to canvas like happens when "Resist Fingerprinting" is enabled.

When that feature is enabled and Firefox is striping images extracted from a canvas, there should be an extra icon next to the lock in the address bar -- it looks a bit like a picture. You can use that icon to make an exception allowing the site to extract images from canvases without the striping.

That post was actually spam as it had a spam link hidden within a period.
