Getting the live map to work in Librewolf

[DryfterX]

If anyone is using Librewolf like I am and finding the live map is completely black it is a Librewolf-specific issue. I was about to submit a bug report here about it and am glad I searched the issue beforehand.

Here is how to get the live map working:

I was having this issue with WebGL recently; I believe it's caused by LibreWolf's anti-fingerprinting measures.

I use FPP overrides instead of the default RFP, and adding -WebGLRenderCapability to the former fixed it for me.

For context, these are the relevant settings in my about:config:

webgl.disabled = false (i.e. WebGL is enabled – I hate the double negative here, but that's Mozilla's fault)
webgl.force-enabled = false
privacy.resistFingerprinting = false (RFP is disabled)
privacy.fingerprintingProtection = true (FPP is enabled)
privacy.fingerprintingProtection.overrides = +AllTargets,-CSSPrefersColorScheme,-JSDateTimeUTC,-SiteSpecificZoom,-WebGLRenderCapability

To mitigate the risk of malicious websites using WebGL to fingerprint me, I use the "Block WebGL" and "Block WebGL – Unbreak" lists from BadBlock in uBlock Origin, which block WebGL by default and allow it on certain sites that need it, respectively.

I hope this helps.

That last part about the BadBlock WebGL UBO lists is important and I emphasized it because with that it will basically do the same thing as leaving those about:config settings unchanged, otherwise you'll be letting any site serve WebGL.
