Firefox Community Forum

We are in an enterprise environment and for years we have had disabled automatic updates.

Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.

Computer Configuration > Administrative Templates > Mozilla > Firefox

- Custom Update URL = Disabled
- Disable Update = Disable
- Application Autoupdate = Enabled
- Background updater = Enabled

We also have a system proxy configured.

Updates do work if someone goes to Help > About Firefox.

Looks like the update interval is once every 7 hours but how is this triggered?

Latest update, 4. oct. Using Firefox Developer Edition. Closed the browser window for the day, and then on opening again it had updated, my entire toolbar, and also icons where the tabs are, are just gone - including the "+" icon for creating a new tab, along with the bookmarks bar having vanished. Picture added below.

It seems like the bookmarks bar is still there, you just can visibly see any bookmarks. Tried adding a new bookmark, but nothing appeared.

How can I fix this?

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

 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.

Hello to all, since I have updated the Firefox to the version 115.15 a notice showed up that this version is not compatible with Windows 7 / Vista, although I use Windows 11-22H2 on my laptop. What I can do to receive regular updates for the Firefox-Browser. Thank you in advance klk

After today's W10 update, I'm getting an error on Firefox:

XULRunner: Error: Platform version 129.0.2 not compatible with

minVersion >= 128.0.2
maxVersion <=128.0.2

What do I do now? It's a Lenovo 64 bit machine.

Honestly, i keep trying to support FF but your releases are making me mad. first off my addons are missing after upgrade, they aren't in toolbar or bookmarkbar, they show enabled, but no control exists I use download all images for years, now there is no way to use it .. with the existing version. https://webextension.org/listing/save-images.html i've used this extension literally for years w/o incident.. damn.. this is majorly annoying and disturbs my workflow

why should i have to 'fix' something that was working prior to the upgrade. this is annoying even if some of the browser functionality is improved, your costing me unnecessary work

also why would you located the + new tab control to the left of the 'tabs', you never open a new tab there, always to the far right hand side, the user now has long mouse movements or short-cuts to open, its' broken theUX I've filed a bug on that one.

please you had to know this release had these side effect where are the release notes and the playbook for restoring this add-on functionality.

Last Pass Firefox extension was working on my Windows 10 computer until 3 weeks ago. Now when I click on extension it hangs. (the extension is red red in tool bar so I know it is correctly installed).. I was able to solve by deleting Firefox extension and instead installed Last Pass 4.0 directly from Last Pass's site. Please fix your extension. This is not a Last Pass issue.

Good morning,

I am developing a browser add-on for Firefox. I would like to ask a question. Is it possible to publish the add-on in an unlisted way, but making sure that when it is installed in the browser it always maintains the same internal UUID (which does not correspond to the add-on ID)? If it is not possible to do this by publishing it unlisted, would it be possible to do so by publishing it in your store in a listed way?

I await your kind reply Thank you, best regards

i am not a computer knowledgeable person, as I am 84 years old, and do not understand or know how to make the changes that are constantly being made. Please help me make sure everything is set up correctly for the current rules and that the computer is secure, as I discuss monetary issues with many of my clients. When directions are offered, I often find it impossible to follow them, as whatever they tell me does not show up, or is not found on my screen. I have a relatively new computer, maybe a year old, so i am sure the problem is with me, and not the computer.

Thanks for any help you can offer. From past experience, please have someone with lots of patience, or some one that can just et it set up right. Thanks, Bette :>)

After recent update bookmarks disappeared. When I restore them and then close firefox developer edition the bookmarks toolbar is gone again. It seems like a bug in that recent update. Please advise.

hello,

is just wanted to know if the new feature "Users in the United States and Canada can view local weather directly on the new tab page. Additionally, they have the option to select a specific location to see current weather conditions.", which was released with the version 130.0 also comes to europe someday?

I updated a few days ago and I noticed that dragging and dropping a tab is creating a copy of the tab in the place where I drop it, instead of moving the tab which was the previous behavior in older versions.

Hello, 1. I can't run Firefox - there is error appeared as screen shot. I'm using Chrome to make it this report and Firefox disappoint me again... 2. Before i had problem with Firefox ver. 30.0.0 - 32bit version was stack on some webpages so I changed for 64bit version and problem gone, but now see pt.1.

I have installed Thunderbird on a new PC desktop running Windows 11, copied all the server settings from my Mac laptop that are working correctly, yet i keep getting an error message that "Thunderbird failed to find the settings for your email account". My ISP will not provide detect support for your client, a "third party provider". What do I need to do?

Today I manually download and rename the firefox executable so a script that runs as a Sandbox is spun up is ready to go immediately. But that entails me manually downloading, then renaming the installer to a name that the script always knows. And often the setup file gets updated on the web and I am running the prior version, or older depending on when I went thru that manual process.

So I am back looking for a way to either find a way to download the newest installer each time or find a way to kick off the internal updater right after its currently scripted install completes. Either could work.

I hate having to use Edge as its the browser MS automatically installs when a sandbox is spun up.

Or are there other ideas on how to accomplish this? Thanks, Bill

The update two days ago has left me with an error message: Platform version '131.0' is not compatible with MinVersions and MaxVersions 130.0.1

What can I do? This is the 3rd update corruption within the last 6 weeks - last time I was told to remove Firefox and install from new so lost at least 6 years history.
