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.

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 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.

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

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?

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.
