Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

Version: Mozilla Firefox for Linux 149.0 Device: Termux v. 0.119.0-beta.3 Output: IceWM 4.0.0 + XServer XSDL v. 1.20.53 Log: ``` $ firefox --no-remote --alsa-output-device=default --display=:0 console.error: "Warning: unrecognized command line flag" "-alsa-output-device" Exiting due to channel error. Exiting due to channel error.

Refresh tried. Malware checked - none. Trouble Shooting mode log: ``` $ firefox --safe-mode Exiting due to channel error. Exiting due to channel error. Exiting due to channel error.
