It sounds like the Google Maps team started using failIfMajorPerformanceCaveat, 
but might be going about it in a user-hostile way!
For Firefox, if you check in the Web Console for that page, if you get a 
message that mentions failIfMajorPerformanceCaveat, then you can bypass this to 
restore webgl creation via about:config, by setting 
"webgl.disable-fail-if-major-performance-caveat" to "true"!
Does that help for you?

Title:
  Firefox 83 Breaks WebGL

Status in Mozilla Firefox:
  New
Status in firefox package in Ubuntu:
  Fix Committed

Bug description:
  Upon upgrading from Firefox 82 to to Firefox 83, WebGL stops working.
  Ubuntu 20.10 with Wayland.

  When I try to launch a webGL game:
  Failed to create WebGL context: failIfMajorPerformanceCaveat: Compositor is 
not hardware-accelerated.

  Specifically Pixi says:
  Error: WebGL unsupported in this browser, use "pixi.js-legacy" for fallback 
canvas2d support.

  Downgrading to Firefox 82 works. Not sure if this is an Ubuntu build
  issue or Firefox, so I also filed upstream as well:
  https://bugzilla.mozilla.org/show_bug.cgi?id=1678652

  I need this functionality for work, and pinning to version 82 will be
  problematic in the long-term.
