Firefox Sandbox implications of User Namespaces being disabled

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem.

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

I have recently noticed that I can no longer see the "comments" sections on various "News" websites. I first noted this with Townhall Media sites (Townhall.com, Redstate.com, Pjmedia.com) and now Foxnews.com. What has Firefox changed that has resulted in this issue? Most of these sites use Disqus for comments. I have tried explicitly allowing content from these sites. I've been using Mozzila products since the advent of Netscape. Always found Firefox to be superior to other browsers, and I'd like a little help in finding out what is causing this problem. Thanks.

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

I transferred by Firefox bookmarks from my old computer to my new Windows 11 computer. I think they transferred fine. But to access them, I have to click on Bookmarks and then go down to Manage bookmarks and click on it. Then I see them on the page that has all the Import and Backup access on it. How do I get them to appear in the side panel as a list like they did on my old computer?

I have Windows 11, Firefox yahoo email. I must have clicked somewhere that consolidated all my email to the left in a narrow format. Can't locate where to correct it. Also had no luck attaching a screen shot. Next to the condensed email, is another column that is blank except for the white envelope. Is there a place where I can change the format? Thank you.
