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!

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!

Hi, we use Firefox 128.9.0esr (64bit) on about 6000 workstations. We redirect the stored bookmarks on a personal network drive for each user. For that we use these settings via Windows group policy:
browser.bookmarks.file = P:\Firefox\Bookmarks browser.bookmarks.autoExportHTML = true browser.places.importBookmarksHTML = true
For some time the automatic export/import with that settings above does not work any more. When I close Firefox on workstation A, the bookmarks seem to be exported correctly in that export-file (check the file via editor). But when I use another workstation B an start Firefox, the exported file does not import on startup. But this worked fine in the past.
I found out, that the switch "browser.places.importBookmarksHTML" is obviously automtically set to false when I have startet Firefox (checking with about:config). I dont know if it is correct.
Any suggestions? Maybe it's a new bug?
Thanks Malte

I am trying to manage Firefox browser for our users with MDM. On doing so, I can't able to get expected output on blocking the camera access for certain websites with the following OMA-URI.
./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Permissions~Camera/Camera_Block
I can add websites in allow section and even lock the setting so that the users can't change. But facing issues with blocking camera access.
Is there any place where I can see the log if there are any error encountering by any chance? Any insights or suggestions would be greatly appreciated.
Thanks in advance!

Hello,
For enterprise solutions, for our browser extension can we disable the switch button where user can turn-off the "Access your data for all websites"?
This can be informed to the end user and also approved by the IT admins.
But the option to disable at runtime on the fly needs to be disabled.

We are currently considering using Firefox ESR as our default browser but experiencing a few issues and one of them is with our configured SailPoint IdentityIQ Single Sign-On Experience, which uses Basic Authentication.
Issue Description First, the login button needs to be clicked multiple times before access to the site is granted. Once signed in, the Firefox inbuilt authentication dialogue appears, prompting the user to log in again (see the attached screenshot). The landing page is only presented after clicking the login button several times. This creates a poor user experience, sometimes causing pages to load improperly. Interestingly, the same process works seamlessly in Edge Chromium.
Troubleshooting Steps Taken I have already attempted the following: 1. Temporarily disabled all custom and security settings in mozilla.cfg and config.json. 2. Temporarily disabled Firefox Tracking Protection. 3. Allowed third-party cookies for the specific URL. 4. Upgraded Firefox Version to 128.7.0 5. Since our Firefox browser is significantly hardened, I have also enabled and reconfigured the following settings in mozilla.cfg to ensure Basic Authentication is allowed, functions properly, and suppresses Firefox’s authentication prompt, but without success:
network.http.phishy-userpass-length = 255 network.http.use-basic-auth network.automatic-ntlm-auth.allow-non-fqdn network.automatic-ntlm-auth.trusted-uris security.enterprise_roots.enabled security.enterprise_roots.enabled
Observations from SailPoint Team Our colleagues from SailPoint have tested the setup in their environment, and according to them, it works as expected. However, their browser is not hardened, and they have leveraged the SailPoint UI for authentication instead of the built-in Firefox authentication prompt.
Further Investigation • Is there a specific configuration required in the user profile settings? • Network trace analysis shows 404 errors on GET requests and the following error codes on POST requests: • 302 Redirect: Mozilla Documentation • 408 Request Timeout: Mozilla Documentation
Next Steps Is there a specific security setting that needs to be enabled or disabled? Are there any particular Firefox enterprise policies we should modify? I have also attached screenshots for reference. Let me know if you need specific logs or network traces for further troubleshooting.

Using group policy there is various settings required for our users. We have been using the preferences policy located at: Administrative Templates > Mozilla > Firefox > Preferences
This policy requires the use of JSON, we have been using the following which has been working ok:
{ "media.navigator.permission.disabled": { "Value": true, "Status": "user" }, "browser.warnOnQuit": { "Value": true, "Status": "user" }, "keyword.enabled": { "Value": false, "Status": "user" }, "browser.tabs.unloadOnLowMemory": { "Value": false, "Status": "user" }, }
Within the old "Preferences (Deprecated)" there is a setting called "intl.accept_languages" which we are wanting to use but I can't seem to find a way to include this within the JSON. We are wanting to set it to "en-GB".
If I enable this within the old deprecated preferences section it causes the Preferences with the JSON to stop working.
I have tried various combinations of including it within the JSON but neither are working:
"intl.accept_languages": { "Value": en-GB, "Status": "user" }
"intl.accept.languages": {
"Value": en-GB,
"Status": "user"
}
I've checked the Mozilla website here: https://mozilla.github.io/policy-templates/ There doesn't seem to be any reference for the intl.accept_languages setting to be used within the JSON
Please can someone advise?

I'm developing a parental control add-on, installed with policies.json. It works... but it's easy to disable it by simply deactivating it in private windows + opening a private window, which kinda makes it useless.
Is there a way to force my add-on to work in private windows, regardless of user choice?
If that's not possible, is it possible to somehow disable private windows while the add-on is disabled in private windows.
Note: I know that I can disable private browsing entirely with policies.json `privatebrowsingmodeavailability`, but I'd rather avoid it. Kids browing privately is a good idea :)

Hello community,
i would like to ask about how to deploy security.pki.certificate_transparency.disable_for_hosts globally for users? With version 135 a lot of production webapps stopped working and as of now , we have to do manual modification in about:config. Our company has over 300k users , so the possible disruption might arise very quickly and there will be significant loses in production enviroment.
Is there a way how to deploy this specific setting via GPO/SCCM ?
Thank you

Hello,
New subscriber here. I have been given the task to test the install and uninstall of the Purview Firefox browser extension using Intune. I created 2 groups in EntraID, one for each (install and uninstall).
I have no issues with the installation. Initially, I left the test device in the install group and then added it to the uninstall group to remove it. (this usually works with other apps, it worked this way with the Purview Chrome browsing extension as well other apps) but when I do this, nothing happens.
Next, I removed the device from the install group and added it to the uninstall group only. Once the configuration profile applies to the test device, it allows the user to remove it manually (before it did not) but the extension remains installed.
I have created a policy using the administrative template extension uninstall option as well as with the OMA-URI settings but the same happens. When i check the device configuration for the device in Intune, it says it succeeded but that is not the case. The OMA-URI setting I was not too sure about, but gave it a shot. I used the UUID value for the Purview Firefox extension
I am attaching some pictures and hope someone can tell me what I am doing wrong. I can add additional information, if needed. I have opened a ticket with Microsoft last week but have not called me yet. I ran into this forum today.
Thanks in advance

Firefox is used on Windows 11 Enterprise. There is a firefox.cfg in the installation directory (and an autoconfig.js in the ./defaults/pref sub-directory). Everything works fine when a pref(...); entry is written to the firefox.cfg. However, we want the firefox.cfg to call the pref(...); entries from a global_config.js which is saved on the machines public directory.
Therefore, the firefox.cfg says:
// free line lockPref("autoadmin.global_config_url","file:///C:/Users/Public/.../global_config.js");
But firefox does not load whatever prefs are written to the global_config.js. There probably is problems with the formatting of the file path (file:///C:/Users/Public/.../global_config.js). What would the correct formatting look like? Unfortunately, Mozilla´s support guide only includes an example code for a firefox.cfg which calls a global_config.js via http:, but not via file:.

Dear Community,
i had .cfg file with following settings to clean up some userdata after closing firefox:
//Clean UP Cache etc. lockPref("privacy.sanitize.sanitizeOnShutdown", true); lockPref("privacy.clearOnShutdown.cache", true); lockPref("privacy.clearOnShutdown.cookies", false); lockPref("privacy.clearOnShutdown.offlineApps", true); lockPref("privacy.clearOnShutdown.sessions", false);
This cleaned the "Storage" Folder in the Firefox Profile folder, but cookies and sessions where remaining, so the logins where active.
Now i saw that all useres have lots of folders in the "Storage/Default" folder. After some research i found out that this behavior startet at 02.10.2024.
I also found a new pref: privacy.clearOnShutdown_v2.cookiesAndStorage which was set to "false". No idea where this key came from? When I set this key to "Yes", the storage is cleared after closing Firefox. But so also all the cookies. Was there a change at the prefs?
And is ther any other solution to clear the Storage but remain the cookies?
Thank you in advance!
