Failed to initialize WebGL in Firefox

[marcjulian]

Issue

Noticed that the map is not rendered in Firefox with the latest deps

• maplibre-gl 5.0.0
• @maplibre/ngx-maplibre-gl 18.2.0

The following error is printed to the console

Failed to create WebGL context: WebGL creation failed: 
* tryNativeGL (FEATURE_FAILURE_CGL_FBO)
* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

ERROR Error: {"requestedAttributes":{"antialias":false,"preserveDrawingBuffer":false,"powerPreference":"high-performance","failIfMajorPerformanceCaveat":false,"desynchronized":false,"alpha":true,"depth":true,"stencil":true,"premultipliedAlpha":true},"statusMessage":"WebGL creation failed: \n* tryNativeGL (FEATURE_FAILURE_CGL_FBO)\n* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)","type":"webglcontextcreationerror","message":"Failed to initialize WebGL"}

Reproduction

Open the ngx-maplibre-gl (https://maplibre.org/ngx-maplibre-gl/) docs in Firefox and the map is not rendered on the home/examples page.

Same error occurs also on https://maplibre.org/maplibre-gl-js/docs/. (Perhaps this issue should be moved to maplibre-gl repo)

Environment

Firefox 134.0.1 (aarch64)
macOS Sequoia 15.2

Seems to be no issue on Firefox Android 134.0

Is it working with a previous version?
Might be related to changes made in maplibre-gl.
Can you check the maplibre.org and examples there (to see if this is related to the wrapper or to the core library)?

[marcjulian]

Yes downgrading to the previous version worked in my app.

• maplibre-gl 4.7.1
• @maplibre/ngx-maplibre-gl 18.1.4

maplibre.org (https://maplibre.org/maplibre-gl-js/docs/) and examples are also effected. My guess its the core library.

[HarelM]

Probably a combination of firefox, webgl 2 and macOS...
Can you check what's the latest version of the 5.0 prereleases that does work?
I tend to say that this is related to:

• Dual-Stack WebGL Runtime with WebGL2 to WebGL1 Fallback #5198

Can check if version 5.0.0-pre.9 is working?

[marcjulian]

Yes, I can confirm 5.0.0-pre.9 works and the error appears with 5.0.0-pre.10.

@0xFA11 can you take a look at this reported issue?

[0xFA11]

I think I could take a look at this.

Just to clarify, this is on Windows, with Firefox and at latest 5.0.0 release but doesn't happen in 5.0.0-pre.9?
This link on Windows on Firefox works just fine for me: https://maplibre.org/ngx-maplibre-gl/demo/display-map
Can we get more specific repro steps?

[HarelM]

Not exactly:
Firefox 134.0.1 (aarch64)
macOS Sequoia 15.2

[0xFA11]

I'm on M1 Max, Sequoia 15.2, Firefox 134.0.1 and this link still works fine for me locally: https://maplibre.org/ngx-maplibre-gl/demo/display-map

[HarelM]

I'm getting an OK results as well on my M2 mac with the above firefox version:

@marcjulian you'll need to dig into it, maybe some firefox configuration issue on your end?

[marcjulian]

I tried the following links again on my M3 mac in Firefox and couldn't reproduce the error again.

• https://maplibre.org/ngx-maplibre-gl/demo/display-map
• https://maplibre.org/maplibre-gl-js/docs/

Also tried to reproduce in my app with the 5.0.0 version and it works without any issues.

For some reason the error doesn't reproduce and I haven't changed any settings in Firefox. I will try to reproduce the same condition in which the error first appeared.
