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.

Firefox popped up an offer to change the screen to dark, which I did. I don't like it, want to change it back. I went to settings but was unable to make the change.

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

Hello,

It seems that Firefox has lost the ability to clear cookies on exit without also clearing history. This affects the current version, 153, but I started observing it a few versions back, maybe around 148.

In Settings -> Privacy and Security, if I select "Clear cookies and site data every time you close Firefox", this automatically enables "Clear history when Firefox closes". If I unselect the latter, the former also becomes unselected.

I would like to clear site cookies and data whenever I close Firefox, but not browsing history. I'm sure this used to be possible in the past. Is it an intended change that this is no longer possible, or is it a mistake?

Thank you.

Currently on Linux, but the problem is probably not OS-specific (although any work-around may be).

What I look for:

I want one setup for work, one for union, and one for personal use. If my work setup would be compromised, union bookmarks, search history etc is not compromised at the same time. Also, my work setup is not cluttered with private bookmarks and addons. Obviously, it'd be nice if those setups could be handled as separate start menue icons, so that I don't need to switch using a couple of clics, but just start the right setup directly. Needless to say nowadays, that these setups need to be syncable between devices. Ideally I as a person would have one Mozilla account that can store multiple profiles and protect each one with a seperate password, OR I as a person would have multiple Mozilla accounts that are made for easy switching.

What I've tried:

Multiple accounts, obviously; they sync between devices, which profiles really do not. The problem I run into is that I still need a separate profile for each account if I don't want to log in and out of them (which I don't want indeed, Alt-Tabbing during my leisure time is the only way for me to get things done for union and often for the office-part of work).

Finding the profile feature was hard enough but I adopted and have the about:profiles page bookmarked in all profiles. But whenever I start using a new computer, I need to set up new profiles. I tried saving them in a custom location on my nextcloud so that they can sync, but there is no straight forward way to import profiles. You need to create new ones and then move the contents of the old ones, instead of just pointing ff to an existing profile; that kind of kills the point of picking a custon location in the first place. All I ever do with a new profile is logging in to one of my already highly profiled accounts.

Along the way I realized that there is a now more GUI-way to create profiles, so I tried that. But when I tried choosing a custom location for them, I failed. Took me a while of restarting and googling to find out that Mozilla has managed to have two completely seperate features with the exact same name! That is, when you create a profile the modern way, it does not appear in about:profiles and vice versa.

Since I ditched the idea of custom location anyway, I setteled with the new way. But when I thought I'd make seperate startmenue links for them, because surely you can handle that with some kind of flag in the command, I could find only one option for profiles, and, as you can guess, it works with the old profiles.

It seems that one can start with a profile at a certain path, so maybe the old way with custom path could be something for me anyway, but when I used such a profile, I got a warning message that says that history and bookmark functions might not work properly and that some security program may cause this.

So, how is one actually supposed to use different accounts OR how is one supposed to sync different profiles between devices?

Hi 🙂 This is a follow-up to https://support.mozilla.org/en-US/questions/1511440.

The problem is this: support.mozilla.org is a site intended for asking support questions, and it is very inconvenient not to be able to use extensions that assist with typing (notably Unicodify and Clippings).

i have 2 suggestions to do:

1) Let the user choose whether to keep extensions enabled (in which case support.mozilla.org is not privileged, the user cannot send "Troubleshooting Information", and there is no security vulnerability), or to send "Troubleshooting Information" (in which case extensions are disabled).

2) Review the design of support.mozilla.org in a way that a subdomain like ffinfos.support.mozilla.org is privileged instead of support.mozilla.org, Firefox sends "Troubleshooting Information" to ffinfos.support.mozilla.org, and extensions are enabled on support.mozilla.org but can never interact with data that Firefox would send to ffinfos.support.mozilla.org.

What do you think about this?

Hi, On previous releases of firefox I could load 8 items across the home display. After upgrading I can only get 5 items and I can't find a way to increase this. I'm a new user so maybe I'm just dumb but I would appreciate some help. linux/ubuntu/firefox desktop. mike_a

My Firefox sync stopped working after the latest update. Bookmarks are not syncing between my desktop and laptop. I have tried signing out and back in but it still does not work. Any suggestions?

After updating Firefox to the latest version, my bookmarks are no longer syncing across devices. I have Firefox installed on Windows 11 and Linux, and the sync was working fine before the update. I have tried signing out and back in to my Mozilla account but the issue persists. Any help would be appreciated.

Hi I noticed that some old links in my history are automatically deleted. How to configure expiration rules (if possible) in order to keep links forever, until manual deletion? I know that links can be saved in the bookmarks, but when browsing the Internet, unless bookmarking everything :(, no one knows if a link can be useful in the future.

Thanks for your help

This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N

Sometimes, the bookmarks toolbar disappear and the history list became hidden for no clear reason. Then, after I reboot my laptop and log in again, everything is back to normal.
