If any maintainers have the time/capacity to review and merge, that would be greatly appreciated! :)

hey, quick question: I've got an angular 4 app I've inherited and while I got the tests consistently running and above 80% it takes 15+ min to run all the tests.
prior to doing any massive changes to optimize things i figured i would try for concurrency to see fi i could get a 2-3x multiplier to the speed.
I am using a recent version of Karma(6.3.4) and i notice that i should have some concurrency by default(infinity) even when i override that with an integer(3) i still only see one browser instance opening.
anyone have an idea what could cause the runner to not run concurrently?
I need to add tests for some project with uses a javascript 3d library that uses WebGL.I am using Karma test runner and using firefox headless mode . by default, the WebGl support was disabled in headless mode of the browser. Is there a way to enable WebGL in headless firefox mode?
@bobby2004170 The launcher for Firefox lives at https://github.com/karma-runner/karma-firefox-launcher. It seems WebGL was not disabled there, but rather it is (or was) disabled in upstream Firefox itself when in Headless mode, thus there is no way for us to enable it other than to launch "Firefox" instead of "FirefoxHeadless" (this should work locally but may require Xvfb in CI or other virtual contexts).
I do note that there is a bugzilla ticket for this, according to which WebGL is no longer disabled for Firefox on macOS and Windows as of Firefox 91 (released Aug 2021).
