When I go to some websites, such as Corair.com it hangs. I cannot click on anything. If I try to access specific pages via a search engine the same happens. I can close the browser but the 8+ processes don't terminate so I have to kill them from task manager.

I clear all of my browser history when I close FF so I can't remember all of the sites this happens on, but it was more than just Corsair.com.

I'm using 140.2.0esr, but also had the problem with 140.1.0esr. I did not have this issue on 128.12.0esr (I upgrade to 140 after that).

I tried turning use hardware acceleration off/on, that didn't fix it.

I am just about to try safe mode.

Hello!

Currently we deploy Firefox via SCCM Package on our machines. The problem is, that Firefox currently only updates itself when you opened it once. This leads to all sorts of Vulnerability warnings etc.

At the moment these regkey settings in HKLM\SOFTWARE\Policies\Mozilla\Firefox are configured: AppAutoUpdate (REG_DWORD) 0x00000001 (1) DisableAppUpdate (REG_DWORD) 0x00000000 (0)

These two are enough for the updates, when the user opened Firefox (and created a profile).

So we tried the information detailed on this page: https://firefox-source-docs.mozilla.org/toolkit/mozapps/update/docs/BackgroundUpdates.html

To achieve a 100% unattended update we added following Key: BackgroundAppUpdate (REG_DWORD) 0x00000001 (1) which yielded no results. Firefox stayed on his old Version (V131 for this example).

We also added pref("app.update.langpack.enabled", false) in the autoconfig.js File as kind of a 'hail mary' action (bc. the documentation wrote, that this setting should be disabled); but it still does not work.

We've been through this rabbit hole quite some times now, and researching it also yields inconclusive results. (answers like: you still need to start Firefox once, before it can update).

So, what are we missing/doing wrong? Is a true unattended Background Update even possible or is "start Firefox once to create a profile" still the only way to go?

Thanks in advance for your time & help

I have a lot of Firefox windows and tabs open, and I really don't want to lose my session.

I wanted to open a webpage in Firefox in fullscreen mode. But evidently there's some kind of serious flaw in Firefox that makes it incapable of opening webpages in fullscreen mode. Everyone says the only workaround is to open the webpage in kiosk mode. So I tried it.

But now I have two big problems:

1. One of my Firefox windows, with all its tabs, is stuck in kiosk mode. (Even if I close the window and then restore it with Ctrl+Shift+T, it's still in kiosk mode.)

2. All new Firefox windows I open with Ctrl+N are also stuck in kiosk mode.

I don't know what to do, and I'd really appreciate any help. Thanks!

Hi guys,

I'm trying to uninstall an extension using a GPO, but it's not working.

I've placed a GPO on the user's OU and configured the ID to be removed in the User-Part of that GPO. I previously retrieved the ID using about:debugging.

But nothing happens; the extension isn't removed. (Logoff/Logon/reboot/gpupdate /force .....)

128.11.0esr (64-Bit)

KeePassXC-Browser Extension

The GPOs for Edge and Chrome have the same function. Enter the ID there, and the extension is reliably removed.

Any suggestions? Thanks

Hello community :)

hope everybody is doing well. I´m coming here with with asking for a help.

I´m managing browsers (Google Chrome, MS Edge and Firefox) in my company via GPOs. What we´ve been dealing with since 135 version came up is having the "Did Not Connect: Potential Security Issue error page , Error insufficient cert transparency" while visiting our internal resources.

Despite of having the security.pki.certificate_transparency.disable_for_spki_hashes set up -> main three certificate hashes are correctly added, basically copying the setup from Chromium browsers , where everything works as expected , Firefox is not.

The only way how to make it work is via security.pki.certificate_transparency.disable_for_hosts , which is , of course, not desirable , because of the security risks.

Does anyone face the same issues ?

Thank you very much ya´ll

I look after about 20 PCs. All Windows 10. All were running Firefox ESR ranging from 115 - 128. As I get time I update each to the latest 128.x. Using group policies I've disabled all update settings.

However, on two of the PCs, they have updated to v139.0.1. Both of the users swear they did not manually do any update. I can't figure out how they got downgraded to the retail channel.

So my question is, since 128 < 139 how can I get them back on to the ESR channel, without loosing history, bookmarks, passwords and saved logins? I gather FF's installer will detect 128 as an older version and throw an error?

ESR -> Retail to me is a downgrade. So is it possible then to upgrade back to 128.11.x?

Each PC is refreshed annually and the only backup of the profile folder I have is from the last refresh, which in most cases in 8-9 months old.

Is there any way to find out why the downgrade happened when group policy forbids it, and the user did not manually download and install the latest version?

When these downgrades happen they break things. For example, when one PC was downgraded to retail his outlook.com email no longer works. If he uses his laptop which is on 128.11.0 it works fine.

Until recently the Firefox docs described how to use the CDP-based Remote Agent at [this url](https://firefox-source-docs.mozilla.org/remote/cdp/Usage.html), now defunct. Here is the latest archive version I can find from the end of last year: https://web.archive.org/web/20241126214503/https://firefox-source-docs.mozilla.org/remote/cdp/Usage.html

One usage example looked like this:

% firefox --remote-debugging-port DevTools listening on ws://localhost:9222/devtools/browser/7b4e84a4-597f-4839-ac6d-c9e86d16fb83

I have tried the same but get no websocket address returned:- ``` % firefox-esr Mozilla Firefox 128.11.0esr ``` ``` % firefox-esr -h ... ... --remote-debugging-port [<port>] Start the Firefox Remote Agent,

                    which is a low-level remote debugging interface used for WebDriver
                    BiDi and CDP. Defaults to port 9222.

... ... ```

`% firefox-esr --remote-debugging-port` command exits with nothing returned

I have `remote.active-protocols` set to 3 in my Firefox prefs.

Please advise how I get the Remote Agent to return a websocket address for use with BiDi with FF 128. My OS is Debian-based Linux.

TIA

I'm using Firefox ESR 128.10.1esr on Kali, and I'm encountering an issue where the 'Refresh Firefox' option is missing from the ☰ → Help → Troubleshooting more Information. This is preventing me from restoring Firefox to its default settings. I've already tried the following:

   Restarting Firefox
   Clearing the startup cache
   Confirmed there are no extensions installed

None of these steps have fixed the issue. I need a way to reset Firefox ESR to factory defaults, but I can't find an option to do so. Attached is a screenshot of the Troubleshooting Information page.

Any assistance would be greatly appreciated!

Hello,

We are trying to automate updating Firefox ESR from 32bit to 64bit. There seems to be an issue with getting user's profiles to properly migrate for ESR. If we do a plain 32bit uninstall and 64bit installation, a new "default-esr-1" profile gets created (which is expected behavior from these Mozilla docs for new installs). But, when we set the MOZ_LEGACY_PROFILES=1 policy, this reverts to using the "default" profile instead of "default-esr" profile that was previously in use.

Are there any known ways around this which does not require user intervention to manually change back to the "default-esr" profile?

Thank you

We're exploring adopting a default deny policy for Firefox extensions in our enterprise. However when I tested this by creating a custom policies.json Firefox unexpectedly removed all extensions for me, including the ones I thought I had allow listed. Here is my policies.json but just keeping in the Facebook Container add-on to illustrate:

{

   "policies": {
       "ExtensionSettings": {
           "*": {
               "blocked_install_message": "Only approved Firefox extensions can be installed, please email your request to itdept@example.org",
               "installation_mode": "blocked",
               "allowed_types": ["theme", "dictionary", "locale"]
           },
           "@contain-facebook.xpi": { "installation_mode": "allowed" }
       }
   }

}

What I would like is to to allow pre-approved extensions (including if they already are installed) and all other types of add-on, but remove and prohibit installation of unapproved extensions.

Can anyone assist, please?
