Progress Circles on Canvas in FireFox

Currently, I am experimenting with this codepen demo that utilizes canvas to generate progress circles:

The functionality functions perfectly in Chrome and Safari; however, it only displays black circles in FireFox. My knowledge of canvas is limited, so I am seeking assistance and suggestions on how to rectify the issue for FireFox.

What steps should I take to troubleshoot? Is there something obvious that I am overlooking?

Answer №1

Don't forget to include a hash symbol when specifying color values:

canvas.strokeStyle = '#' + color;

This quick fix should solve the issue, but remember to always prefix color values with a hash symbol when passing them. This workaround is due to Chrome being more lenient in this aspect compared to Firefox, which is why it functions correctly there.
