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?

So, I'm switching from Chrome and there's this one thing I can't seem to be able to replicate in firefox.

When I start my day I usually open several tabs from different pages of the same website. In Chrome, I would do that by: -typing the name of the website in my address bar -all the pages I frequently visited in that website show in my suggestions -I middlemouse-click all of them, one after the other -this opens one new tab for all of them -I then switch to those tabs and browse them

However, replicating this in firefox seems impossible. When middle-mouse-clicking the 1st link, I would have my window forcibly switch to it, not letting me open the other tabs without changing tabs again. Recently I learned I can avoid this forced switch by middle-mouse-clicking the URL on my address bar while holding shift, which is great! . . . Except it still closes my address bar, not letting me click the other ones without having to type the website's name in it again.

I don't mind holding shift (though I wish I didn't have to) but I really just want to middle mouse click multiple links in my address' suggestion bar and open them in succession, without shifting back to it after each time.

how can I configure android Firefox to let me change the name of any downloads without it downloading without giving me a choice?

this is unacceptable browser programming that Mozilla should have FIXED a VERY LONG time ago.

Firefox 127+ Downloaded Filenames Appended With Underscores In Some Circumstances

Problem: When exporting or downloading content from the GUI in the digital forensics tool Velociraptor, underscores are appended to the beginning and end of filenames. File is otherwise downloaded correctly, but removal of underscores necessary if original filename is desired. One hypothesis is that perhaps for security reasons there were changes made in Firefox 127 for how character escaping is performed.

Tested Operating Systems: Ubuntu 24.04, Windows 11 22H2, Windows 11 24H2, macOS Sonoma (14.5) Affected Firefox version(s): Confirmed 127.0, 127.0.1, 127.0.2 Tested Firefox versions which do not reproduce the behavior: 126.x, 125.x > Testing Microsoft Edge, Chromium, Google Chrome on Windows, macOS, Linux: files download with correct name as expected. Testing performed with clean installations on clean VMs with no add-ons enabled.

To reproduce: Download the latest release of Velociraptor from Github (at the time of this writing, 0.72.3) for preferred platform / operating system. Run Velociraptor using the gui switch, e.g. "$sudo velociraptor-v0.72.3-windows-amd64 gui" or "$ velociraptor-v0.72.3-windows-amd64.exe gui" Navigate to Server Artifacts and click the "+" icon at the top Search for Server.Utils.CreateMSI - select and press Launch Select the newly-created flow, click "Uploaded Files" tab and click vfs_path to download the file or, click the Notebook tab and click Download JSON or Download CSV buttons to download JSON or CSV respectively, underscores are appended to beginning and end of filenames.

I am finding more and more sites that I regularly go to are no longer working on firefox. One site was because HTML5 apparently does not work on firefox. But others I don't know about why are no longer working on firefox. I thought it might be streaming related but just today I could not access one of my banks on firefox, and I tried many times, but had no problem signing on using Chrome.

Disable hardware acceleration for PDFs only?

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

I click the Share Data button, and instead I get a complaint every time, that "We can't automatically get your browser's troubleshooting data, please try these manual steps." I ain't falling for that no more, every time I click that manual steps thing, it blanks out everything I already typed, and when I come back I have to start over!

Anyway, how do I get that complaint to go away, and the details to appear in the Troubleshoot Information box like they ought to?

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
