Steps to reproduce:

According to the spec, EXT_color_buffer_half_float should be supported in WebGL 2.0 contexts https://github.com/KhronosGroup/WebGL/pull/3146.

However, if you visit https://webglreport.com/?v=2 with the latest Firefox version (e.g. v133), it misses the EXT_color_buffer_half_float extension.
