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 keep getting the error in the image and can't use my tabs at all . The search loads for 10-15 seconds and then I get the error. I have tried troubleshoot mode too !

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?

In the Add Bookmark menu that is accessed from the address bar, the field for adding a keyword shortcut is absent. This is the same menu that is accessed by Ctrl + D. It's ironic that the menu accessed via a keyboard shortcut is missing the field for adding a keyboard shortcut.

"Tags" field is present on all, but I find it orders of magnitude less useful than keywords.

Dear friends,

Update on the question below. Attached you will find data about my system.

For a better understanding I have created this video. https://cloud.haller.family/s/Zyt9DFoCnFwtgn8

Description of the video: From the form I call up the homepage ostseesattel.com. Then I click on the guestbook form. Unfortunately you cannot see the pointer. There is no reaction.

Then I change the tab back and forth. Now the guestbook can be clicked on.

Why is that?

Kind regards Uwe

Dear friends,

I am using Firefox Browser 127.0.2 (64-bit) on a PC.

Sometimes it happens that an input field on a page in an IFRAME cannot be clicked. The buttons work, but you can't enter anything in the text field.

Only when I press in the address bar and then in the text field, now I can enter text in the text field.

Example page https://www.fantastic-food.ch Then click on the "Feedbacks" link.

Does anyone have an idea?

Kind regards Uwe

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”?

Google search engine suddenly stopped working on my Firefox app on my laptop. Please tell me how to fix this. I have already checked settings and Google is the preferred/default search engine.

I'm using a macbook air, and I was trying to use the fingerprint login thing, when instead of unlocking my puter it shut down the whole thing and it started to make very loud fan noises. I waited a few minutes for it to stop, then got back on, and my bookmarks and saved passwords were deleted from firefox. No passwords or logins were reset on any other applications. This is very alarming since I had just made an email and some accounts to manage some event I'm holding, and now the password I trusted to firefox is lost. I need this password, as otherwise I cannot log into my email since I hadn't time to set up recovery measures (I have tried to recover it, but there's insufficient evidence for google that I own the account :/ ).

I tried looking through my browsing history for anything helpful, but everything was deleted from there as well. I also was not logged into my Mozilla account at the time either, so I am really in some sort of predicament here, , I'd appreciate any advice and ideas here!!

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!

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

Firefox keeps going off for from 5 seconds to about 20 seconds. It happens several times a minute. The screen goes blank and I can’t click on anything. Really aggravating. I would appreciate any help. Thanks

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

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

For the past couple of weeks I have been getting the "Hmmm, We're having trouble finding that site" error screen quite often from both searches and links from other sites. It's always happened once in a while but it hasn't been anything bothersome. However recently it has become quite bothersome because it's happening a lot! However not all the time. It's not completely broken, just mostly. And it's happening while trying to visit sites that I know and visit frequently such as Amazon, Ebay, and even sites for local businesses that I trust and know are working. I'm not having any internet issues with my home wifi, nor am I having this issue with other browsers. I have however also noticed it on my Firefox mobile browser as well. I posted about this a few days ago and got some email back about an issue with my post. If this happens with this one and I'm unable to get this resolved I will just get rid of Firefox on my devices. FF has been a long time favorite and is usually set as my default browser but if stuff like this is going to continue, I can change that real fast. There are plenty of other browsers that work just fine and have decent customer support.

I have a lot of tabs open, and I don't know which are responsible for the popups. Previously, I'd get 2-3 unexpected popups per day (that were not triggered by navigation in visible tabs), but since yesterday, every ~10min I'm getting 2 popups right after each other.

How do I find out what tab is triggering them?

Besides the annoyance, I find it worrying that firefox apparently "intends" to input login details into background tabs - if I had entered my master password previously, I wouldn't even notice that the password store had been accessed.

It would be really nice if the master password popup had a button to view the triggering tab (and perhaps highlight the fields that would have been filled after unlocking), but until that happens, I really need some way to locate the problematic tab(s)...

edit: changing the "fill usernames and passwords automatically" as well as "ask to save passwords" settings did not prevent the frequent popups from occurring. Even worse, while such a popup is open, firefox seems to be unable to load new pages in any tabs, and interactive applications (eg. google sheets) lose their connection until I close the popup...

If you are currently using a normal window then there are ways to open a bookmark or link in a private window. But if you are currently using a private window then how would you open a bookmark or link in a normal window?

I have tried several things including pressing shift+enter or choosing "Open in new Window" from the context menu, but this just opens the bookmark or link in a new private window.

My current method is to copy the address of the bookmark or link then paste it into the address bar of a normal window.

But is there a more direct method of opening bookmarks or links in a normal window, if currently in a private window?

Thanks.

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?

Ive been with Firefox since 0.4 20+years and am thinking of binning this browser. The Firefox updates wipe your bookmarks ,your page set up with the 4 rows and your preferred sites they then push in the boxes last visited or recommenced stories i had to reinstall and older version,get bookmarks from a different drive i have to get back to where i was.

  I have turned off updates but am continually bombarded with download latest version,Firefox used to be great ,you got what you want,no adds,no pushing stuff its starting to feel like google chrome.
  So before i bin it,is there any way you can save ALL your setting as you like them and reinstall them with your preferences as was?     If not i will give Duck duck go, a go as my new browser.

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
