Latest Version of Firefox Breaks Rendering

[muzzeno]

I love this script and use it daily to render webGL animations. Unfortunately it looks like the latest Firefox update v55 breaks the rendering process. It took me awhile to figure out what was going on, but once I downgraded to Firefox v54 it worked flawlessly again. I assume this is related to the security part of the release notes. (https://www.mozilla.org/en-US/security/advisories/mfsa2017-18/). When on v55 the render can still be downloaded but it contains empty black frames for PNG sequences/gif frames.

Hope this helps someone else.

I just tried the example in Firefox 55.0.3 macOS Sierra, and it worked correctly, the PNGs are correctly generated and packed. Could this be an issue with your rendering or the interaction between your rendering and ccapture on FF55?

Hmm maybe it the OS difference and FF55? I am currently on El Capitan, and within a 24 hour period animations that rendered perfectly were spitting out blank frames. The only change that I discovered was FF updated within that time frame, and downgrading instantly fixed it.

It looks like I have an El Capitan update to install and if that doesn't work I will try updating to Sierra later today to see if it makes a difference. Thank you again for the fast response and for the awesome library!

Is this still an issue?

Works with Sierra and Firefox 55.0.3 as you suggested. Seems to have been El Capitan causing the issue after all.
