User Story

platform:windows,mac,linux,android
impact:blocked
configuration:general
affects:all

Environment:
Operating system: Ubuntu
Originally reported Firefox version: Firefox 105.0
Last reproduced with the following UA: Mozilla/5.0 (X11; Linux x86_64; rv:126.0) Gecko/20100101 Firefox/126.0
Platforms reproduced on: windows,mac,linux,android

Steps to reproduce:
The website does not work in Firefox. It shows "WebGL is not available" and does nothing more.

The website uses some kind of feature detection to determine the availability of WebGL, EXT_color_buffer_float, and something nicknamed "isManualMipMappingSupported". The console logs "WebGL warning: readPixels: Format and type RGBA_INTEGER/UNSIGNED_BYTE incompatible with this RGBA8UI attachment. This framebuffer requires either RGBA_INTEGER/UNSIGNED_INT or getParameter(IMPLEMENTATION_COLOR_READ_FORMAT/_TYPE) RGBA_INTEGER/UNSIGNED_INT.".

The author of the website mentions over here: https://news.ycombinator.com/item?id=32742468 that they find the WebGL implementation of Firefox to be "severely broken".

Works in Chrom[e|ium]. Shows an page in GNOME Web.

Actual Behavior:
Browser unsupported
