Note the force_enabled by user: Force enabled by envvar on top - so it's still enabled, just not enabled automatically, which we will do using a blocklist. You can verify by all the extensions starting with EGL - they would otherwise start with GLX and in parts have different names :)

They do seem to be listed. I however checked because the firefox window was not supporting transparency effects, as in the image. The strange black border should not be present and the chrome should be transparent due to userChrome changes. I thought this was the offending cause, but it seems it could be something else

Yeah, found it and added myself to CC list. Hopefully it is solved faster. I prefer to use nightly as daily driver in linux and it is quite irritating but not quite deal-breaking
