[Resolved] Stones displayed as white sqares in Firefox ESR

Hi All, I’m not sure if this is the right place to report bugs, but here it is:

On my Firefox ESR (60.7.0esr, Linux) all stones are displayed as white Squares. I saw no Errors in the Javascript console.


That is a firefox “feature” that breaks canvas rendering in the name of combating fingerprinting. I’m not sure how one would use that for fingerprinting, we certainly don’t, but we do use canvases to draw those stones. You can learn more about it here: https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting?as=u&utm_source=inproduct

You can also switch to using the “plain” stone theme which works since it just draws circles instead of compositing images.


If you’re really interested. here is a paper about it :slight_smile: http://www.w2spconf.com/2012/papers/w2sp12-final4.pdf

Anyway, thanks for your help.


your link was broken but found it here: https://www.ieee-security.org/TC/W2SP/2012/papers/w2sp12-final4.pdf

Interesting stuff… well hopefully they figure out how to not break anyone wanting to fiddle with pixels while still protecting people.
