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.

в моменте браузер перестал запускаться , я люблю твикать и оптимизировать виндовс подумал дело в ней , но переустановил виндовс скачал обновления виндовс и начал по одному шагу оптимизировать и делать настройки виндовс , по итогу настроил точно так же как и раньше , но браузер работал , скачал античит фейсит и перестал работать , сейчас переустановил виндовс не настраивал вообще только скачал браузер и античит фейсита и браузер перестал запускаться выдавая ошибку

I've rebooted, even did a hard reboot, total 3 times, tried system restore, 1 hour past update, deleted Firefox, reinstalled, still "in use", deleted Norton, still same. Reinstalled norton. There NO BUTTON, SWITCH, there! I can File, new blank page, still nothing. Sort of reminds me of automakers, all look alike! Left side, simple, turn on sc or import, at the opening first time, import short cuts and bookmarks from previous page, turn off Newsweek. Simple, without the hassle of now, those that have cleared, happy for you! For me same thing at the top, yellow bar, "in use!"

I had been using the Mozilla Firefox VPN for a few weeks, but now it will not launch. I sign in without a problem but when I click on the VPN icon on the toolbar, nothing happens. I just get the pop-up to try the VPN and "Get Started" (see attachment).

Please advise.

I cannot get into Firefox due to an error message that keeps coming up. Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I have tried deleting and reinstalling it, but it didn't really uninstall completely. I have tried a few suggestions from online, which didn't work. I also tried right clicking on the Firefox symbol and went into some of the different options, but nothing worked for me.

I got so frustrated with not being able to reinstall Firefox because I kept getting the error message "Your Firefox profile cannot be loaded. It may be missing or inaccessible". So I deleted all the profiles after copying them to an external hard drive. Then I copied the file ending in.test from the Old Firefox data folder on my desktop to the AppData/Roaming/Mozilla/Firefox/ profile. Then I copied the biggest file ending in .default from the backed up Local profiles to the AppData/Local/Mozilla/Firefox/ profile. It doesn't matter if I delete or keep the Old Firefox data folder on my desktop, I still get the Profile Missing error message. What can I do, so my laptop would appear as if it had been powered up straight out of the box and never had Firefox initially installed or what do I do with my profiles to make them accessible?

When starting firefox I had 5 windows open. After a MAC notebook restart, I tried to open firefox and then the five pages showed to disapear when I clicked on one - nothing can be seen. On the firefox icon I cannot do anything other than look at "About firefox" to learn that it is up to date. I have no idea what to do to get it started again ... thank you so much for any guidance here

My firefox is completely broken and I have no idea why it just happened out of the blue. I open firefox and all i get is a blank screen. It won't go into troubleshooting mode nothing. completely broken. I have tried uninstalling and reinstalling no luck I'm at a loss please help. Thank you

Here is the troubleshooting information if this helps

I have used firefox for 13 years now and I have never had any major issues with it. but recently I have noticed that whenever I open it on my laptop, the laptop freezes and then a black screen, then a mozzila firefox crash dialog box. sometimes I am forced to hard restart the laptop then use another browser. I still want to continue using Firefox but that issue is really frustrating.

Thank you

By Firefoxwss working great the last time I used it it is the primary search engine for my iPhone 17 as well as my Mac however, when I loaded it today it the screen just said blank. All of my bookmarks are on Firefox. How do I get this fixed quickly? I am, right now being edited. I’m sitting here looking like a fool because I chose to use Firefox rather than Safari or Google. First question they ask me why are you using Firefox. And then, of course, Firefox /x I/ dies all of my bookmarks are on Firefox. Firefox will not open! I have used Firefox for the last nine years. Never had a problem until today when I needed it not to have a problem.
