I currently have Firefox 149.0.2 rapid release channel on Win10 Pro ESU.

I want to switch to the ESR channel.

How do I do that?

Is there anything I should be aware of to avoid problems?

Thanks!

I am currently on 133.0a1 (2024-10-04) (64-bit) Nightly and the new tab button to the right of the tabs is missing. It will show up sometimes, but I have to go to customize and move some things around, then start browsing and it will pop back up.

I use that button often, how do I get that back?

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

The last update did something to my search bar. I still have it, but when I click on it, it moves to the upper left corner, prevents me from seeing my tabs, bookmarks etc. How can I disable this annoying change? If someone has the answer, I would greatly appreciate it.

Tenable is reporting 128.1 and 128.2 as affected by vulnerabilities covered in CVEs' in their plugin 205009 ( https://www.tenable.com/plugins/nessus/205009 ). The rule they are applying is: Mozilla Firefox < 129 That implies that 128.1 and 128.2 are also < then 129 -> therefor vulnerable. Can you please answer 2 questions:

• are Firefox 128.1 and 128.2 part of the same branch of product as 129? Or are they necessarily ESR?
• are Firefox 128.1 and 128.2 affected by CVEs' covered in their TENABLE plugin 205009?

Many of Linux Distributions take firefox binaries from https://packages.mozilla.org/apt/ as given in the Mozilla Knowlege Base Article Install Firefox on Linux. In this article there is a option to Install Firefox .deb package for Debian-based distributions.

However the binaries and libraries that are hosted in Firefox repositories are not compiled with the PIE/PIC flag. That prevents Firefox browser from using ASLR capabilities and to a large degree prevent Buffer overflows attacks. Please refer to the output given below for more details.

$ file -e elf /opt/firefox/firefox /opt/firefox/firefox: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) $ $ readelf -h /opt/firefox/firefox ELF Header:

 Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 
 Class:                             ELF64
 Data:                              2's complement, little endian
 Version:                           1 (current)
 OS/ABI:                            UNIX - System V
 ABI Version:                       0
 Type:                              EXEC (Executable file)
 Machine:                           Advanced Micro Devices X86-64
 Version:                           0x1

The output of the first command is ELF 64-bit LSB executable, which indicates that it is not a PIE executable. If it had been a PIE executable then it would have been ELF 64-bit LSB pie executable. Similarly the output of the second command has a Key, Type, whose value is EXEC (Executable file). However for a PIE binary the value would be DYN (Position-Independent Executable file).

Can Mozilla please compile the binaries and shared libraries with the PIE/PIC flag and then host them in its repositories? Many of Linux Distros do not have the bandwidth to take the source and compile binaries for different architects and are dependent on Mozilla to provide the same. Doing so would be appreciated and would help in enhancing safety of Linux users who use Firefox as their primary browser.

PIE = Position Independent Executable PIC = Position Independent Code ASLR = Address Space Layout Randomisation. PIC and PIE are used interchangeably and imply the same thing.

Yesterday, I installed whatever the current version is for Windows 11. At some point after that, it hung. It wouldn't close, even after doing End Task in task manager, nor shutting down the PC.

When I try to start it, it tells me "Firefox is already running, but not responding. The old Firefox process must be closed to open a new window."

Go to task manager, but the only thing I see related to Firefox is under Details pane. Shows a PID but I can't kill it even using the taskkill command as admin:

C:\Windows\System32>taskkill /im "firefox.exe" /t /f SUCCESS: The process with PID 24344 (child process of PID 19568) has been terminated. SUCCESS: The process with PID 15724 (child process of PID 19568) has been terminated. ERROR: The process with PID 32008 (child process of PID 8260) could not be terminated. Reason: There is no running instance of the task. SUCCESS: The process with PID 19568 (child process of PID 20576) has been terminated.

The PID noted above shows a location of C:\Program Files\Mozilla Firefox\tobedeleted, but if I try to delete it (or any other tmp files with yesterday's date), it says they're open in Firefox and won't let me.

Attempted uninstall and reinstall. Same issues as above. Firefox is now unable to be used. I have a ton of bookmarks that I haven't backed up recently by the way. I do NOT want to lose them.

Hey there! System: Windows 10 x64, Firefox Nightly.

Problem: Out of the blue, when I start Firefox Nightly (I think 2-3 days ago), it just crashed with no extra info. I see the "window of the update process", it goes to the middle or to the end, immediately closes and doesn't bring up the Crash reporter. However! When I tried to run a Nightly Installer that I downloaded through Chrome, it quietly runs and then just opens up my browser no problem, profile and all. I checked and it seems to be the exact same .exe file (according to the Task Manager).

So in short: it breaks if I run it straight from my usual shortcut, or with .exe. But if I run the installer myself, the browser opens up fine.

However, the installer didn't bring any new updates that would fix the problem, I have this for 2-3 days now, I don't remember. I start working, I see I didn't fix it and run the installer again.

Any ideas on the fix? I would love to not lose my profile, settings and, if possible, tabs. I'll try disabling all the extensions after I post this, I don't think they contribute, though (seeing how the external Firefox Nightly Installer opens up my browser just fine).

Thanks in advance!

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Good morning,

We are seeing that the key "DisableAppUpdate" being set to TRUE in about:policies. Not sure why this setting is being set. The result of the setting is "Updates disabled by your organization". So we cannot manually update firefox and are not sure why the setting is being set.

We used Procmon to capture logs:

Line 5169544: "2:29:45.2062951 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169546: "2:29:45.2063211 AM","firefox.exe","1720","RegEnumValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox","SUCCESS","Index: 0, Name: DisableAppUpdate, Type: REG_DWORD, Length: 4, Data: 1" Line 5169547: "2:29:45.2063338 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1" Line 5169548: "2:29:45.2063563 AM","firefox.exe","1720","RegQueryValue","HKLM\SOFTWARE\Policies\Mozilla\Firefox\DisableAppUpdate","SUCCESS","Type: REG_DWORD, Length: 4, Data: 1"

Is there anything in Firefox that can trigger the setting of this key?

у меня был VPN mozilla, сегодня он просто исчез!!!! что это было?? установила MozillaVPN.msi , она запускается и сразу исчезает, даже не могу ввести почту, что за бред???

I can't sign in to my Google account and chrome is my preferred browser and I am getting messages saying that I am signed in to another browser. I want to try uninstalling Firefox and hope that will allow me to get signed in to my Google account.

Before purchasing, I verified that Mozilla VPN will work on Chromebook (shown on the FAQ page for the VPN). Since I can't install software on a Chromebook, how do I go about using Mozilla VPN on it?

Greetings to y’all I am setting up a Microsoft Surface pro 7. Several days ago I installed windows 11 Pro on the machine.

I have tried to review previously loaded Extensions. For each of the Extensions There is a message:

"Can’t read and change data on this site"- listed after each extension. What is this about? How do I access settings for extensions?
