Details

Affected versions

  • Firefox 78.0 RC
  • Latest Nightly 79.0a1

Affected platforms

  • Windows 10 64bit
  • macOS 10.15
  • Ubuntu 18.04 64bit

Steps to reproduce

  1. Start Firefox
  2. Visit the following demopage: https://codepen.io/Alca/pen/mWBoOO

Expected result

  • The demo works without issues, animated text with refresh screen effect can be seen.

Actual result

  • Beta/Release: No animation can be seen in Firefox, also when clicking inside the demo, the background turns white.
  • Nightly: Text animation can be seen, but the background stays white.

Regression range

  • Not a regression since I went to Firefox 45 (rc and nightly) and the same behavior can be seen there as well. Older then 45, the demo is not displayed at all.

Additional notes

  • Chrome and Safari displays the demo just fine.
  • Since this is an old issue I don't think the severity should be that high, my suggestion would be a S4.
Has Regression Range: --- → irrelevant
Has STR: --- → yes
Severity: normal → S3
