OK - I must be missing something. On my previous browser, Opera, if I wanted to see details of my passwords then I needed to put in the computer password, so keeping them quite secure. However, Firefox seems to let anyone using the browser to access the full details of all my passwords, even offering to copy them! This has to be the most insecure approach possible - surely this can't be correct, can it?

NOT to remove personal data? Does it give you an option for personal date not to be removed?? what about all the stored password? Can one of you tell me why all of sudden I get this error COULDN'T LOAD XPCOM? can you send me a link where to reinstall new version on top of the one I have running now Thanks

Firefox is my favourite browser so I prefer using it in all my online activities. When I go to Adobe Firefly though, I consistently get a warning that this browser is not compatible and they suggest using Chrome, Safari or the latest version of Firefox !!! I am using the latest version available, 127.0.2 but Adobe does not detect it correctly. I have to switch to Chrome, that I'm not very fond of. I saw that a similar issue was posted 10 months ago but it's now archived and I can't even include a link to it here :( So, I hope this comment helps in case others have the same problem. I also hope Mozilla can fix the bug or whatever gets in the way. Lenovo laptop - Windows 10 updated Thanks!

Is about:config > app.update.auto set to false sufficient, How to Disable Firefox Update Notifications: A Step-by-Step

Or how about the registry? Turn Off Update

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.

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?

Regular download works fine, but when I try to download attachment in outlook.live.com website, it didn't ask me where to store it, but simply places it in my default location, while at the same time opening the attachment even though I only want to download the file.

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”?

Hello, when in the library, pressing F6 is meant to "Focus Search Field". This is documented at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

However, since a recent update this no longer works. Instead, pressing F6 now switches the keyboard focus to the lefthand tree pane. A further press of shift+tab is needed to move to the search box.

My questions are: Has F6 stopped jumping to the library search box for anyone else? If so, was this a deliberate design choice? Does anyone know of an alternate keyboard shortcut to jump to the searchbox? Finally, is there anyway to revert to the old F6 behaviour?

Even if you can only answer the first question that would help, so I can determine whether or not it is just my Firefox. Although I have already tested in a brand new profile with the same results.

Thanks.

I do not have any ad blockers and have disabled "Block pop-up windows" in Firefox and turned off "Enhanced Tracking Protection" for sites but I still get the message that I am blocking ads.

Every time I use YouTube on Firefox it feels like a mental torture. It starts off with micro-stutters initially - annoying but nothing crazy. After some time the loading speed of the website and the videos themselves increase dramatically. And eventually it becomes unusable:

• Scrolling feels like the website is running at 30 fps
• The videos take several seconds to load
• It also takes multiple seconds to catch up when you select a specific moment of the video

The only solution so far has been restarting Firefox entirely, just close and open and pray. Then the problem comes back after some time.

Solutions I Tried:

• Disabling AdBlock (didn't work)
• Enabling Hardware Acceleration at all time (didn't work)
• Uninstalling unwanted Extenstions (didn't work)

All of these problems disappear when using Chrome or Edge.

about a month ago youtube was only letting me watch videos in 720 or 360, as of about a week ago i only have 360. i've disabled every single extension i have and i have firefox version 127.0.2.

i'm not having this issue in edge, so i assume it's firefox specific. anyone know what's going on or what i can do?

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

When you check the image, you can see two "HOME" entries. This is an issue I discovered after uninstalling and reinstalling the Firefox browser and using Sync.

HOME is my PC, and this image was screenshot on my laptop.

Additionally, the Sync for these HOME entries is not functioning properly. I tested this by opening several sites, and while Sync works well from my smartphone to my PC, it doesn't sync properly from my PC to my laptop.

Does anyone know how to solve this problem? I tried rebooting my PC, but it didn't work out.

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

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?

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".

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.
