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?

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

I can no longer download pdf's (bills, statements,etc) Downloads come in with "name.pdf.part" When I delete ".part" then I can open file. If I don't change name it reverts to pdf.part extension. It's a pain renaming every download. Please help me, I don't want to switch to Chrome. Thanks!

How do I stop these recurring update notices? Every 3 seconds. I'll update when I am ready as this current one does not affect me at all. For a while I fell for it, stopped what I was doing and did the ridiculous update, it still continues! I can move on to a different non-Mozilla browser if I have too. Return the option to not update and/or do it manually. FF127.0.2

I'm using Firefox 127.0.2 on Arch Linux. In settings under General>Startup>"Open previous windows and tabs" is not checked. Under about:config browser.sessionstore.restore_on_demand is false, and browser.sessionstore.resume_from_crash is false

How do I get Firefox to give me a clean slate after restarting my computer?

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

My old 'Legion' laptop had my (I'd guess) open tabs history from late June! I now have a new laptop, and I logged into Firefox, and didn't see all history from June. I need those 'previous' sessions... Where are They??

i am trying to find out how to capture an entire web page. Appparently Edge provides such an option with a camera icon. How can i do a similar function in Firefox. Are there add-ons perhaps?

I have Firefox currently installed on my Windows 10 computer as a backup browser. Normally I don't run it and it isn't the default browser. However, for the past couple of days the Firefox Crash Reporter keeps popping up when I don't even have Firefox running. I can't see anything running in the Task Manager that looks as if it might be related to Firefox. Why on earth does this keep happening?

So, I've switched to Firefox as my main browser (I was using it before, but as a secondary option) and I've spotted this native extension called Pocket.

When I pressed it, I was on YouTube Music already, so it automatically saved that url. Now, the reason of contacting support is more of concern than anything. When I pressed it, a weird message has been attached to it, so I am wondering why, as it is confusing to say the least. I've attached a screenshot with the saves, which also has the weird message and YouTube for comparison next to it.

Thanks.

I can't connect to Amazon.com. I keep getting the following error message:

Secure Connection Failed

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I think this is a problem with Firefox. Any suggestions or should I switch to a new web browser?

I appreciate any suggestions.

Hi, To who it may concern, a big thank you. I am a longtime Linux Firefox user. I had a secondary password, but somehow it has been deleted. I have changed my primary password and I have full access to Gmail, Youtube and other Google pages. My email address has always been the same for many years. It is recognised by Firefox when I type "My account on Firefox" though I am not allowed to enter another secondary email address.

I am almost 80 and not very computer literate.Kind regards,

Patrick Van Niekerk.

Why am I getting the message below every time I try to go on the The Great Courses website? The Great Courses Customer Service Dept it is Firefox that is blocking me from accessing their website. Please tell me how to correct the problem.

"You don't have permission to access "http://thegreatcourses.com" on this server.

Thank you.
