All our Firefox browsers (version 99.*, Windows 10 Pro or Enterprise) in the company need around 20 seconds to load a web page when first opened. All other browser functions work fluently from the beginning. Also the slowness only happens after opening and not during further use. Which Firefox is refusing to load I can open other tabs and e.g. do a Google search and then the "slowness timer" starts again (independently if the first tab is closed or stays open) and refuses to do anything on that tab. Once the slownedd period is over all tabs are loaded and no further problem occurs. This issue occurs only when the GPO "URL for Home Page" is applied. But this page is reachable and when Firefox is working it loads within milliseconds. For testing I created a new profile and on the first startup the problem already occurs. And all other startups too. When temporarily removing this one GPO entry it immediately works again fluently. It also doesn't matter what I set as home page (company internal website or some random web page); it is always slow once this setting is in place.

Hi All- I am in charge of deploying Firefox ESR to my company and trying to get it to silently auto update on it's on with user interaction. We have policies in place (GPO) that prevent it at this point. I need some guidance on whether I should use just GPOs to manage this or should I go the route of the .cfg file? If someone has a step by step on how to best achieve this I would appreciate it. I am currently using the .msi installer.

Here is settings in an old .cfg file that I am testing with:

lockPref("app.update.mode", 1); lockPref("app.update.service.enabled", true); lockPref("extensions.update.enabled", false); lockPref("extensions.update.autoUpdateEnabled", false);

// Set default homepage - users can change // Requires a complex preference defaultPref("browser.startup.homepage","data:text/plain,browser.startup.homepage=http://workday");

// Don't ask to install the Flash plugin lockPref("plugins.notifyMissingFlash", false);

// Disable Search Engine automatic updates lockPref("browser.search.update", false);

//Disable telemetry lockPref("toolkit.telemetry.prompted", 2); lockPref("toolkit.telemetry.rejected", true); lockPref("toolkit.telemetry.enabled", false);

// Disable health reporter lockPref("datareporting.healthreport.service.enabled", false); lockPref("datareporting.healthreport.logging.consoleEnabled", false); lockPref("datareporting.healthreport.uploadEnabled", false);

// Disable all data upload (Telemetry and FHR) lockPref("datareporting.policy.dataSubmissionEnabled", false);

// Disable crash reporter lockPref("toolkit.crashreporter.enabled", false); Components.classes["@mozilla.org/toolkit/crash-reporter;1"].getService(Components.interfaces.nsICrashReporter).submitReports = false;

// Don't show WhatsNew on first run after every update pref("browser.startup.homepage_override.mstone","ignore");

// Don't show 'know your rights' on first run pref("browser.rights.3.shown", true);

Hello! As you may know, FireFox does not use the Windows Certificate Store by default. Therefore I have to change the "security.enterprise-roots.enabled" in the preferences on each workstation. I have searched and found ways to enforce this change by GPE , but I wonder if there is a way to change firefox preferences, especially the one I've mentioned, via Registry Editor.

Hello

We use our own CA to secure some websites on the internal network. Until version 101.0, the SSL was working correctly. I have updated today to firefox 101 and all our internal websites started giving SSL_ERROR_BAD_CERT_DOMAIN. There are no issues with external CA issued certificates, so I'm assuming it is something related to the way we generate the certificates. Were there any changes done at version 101 which might reject certificates with a valid common name? Is there a way to disable it and revert to version 100 options?

Thank you

I manage SCCM in my environment, and have been successfully offering Firefox ESR for a while now, along with silent updates when new versions are released.

Today I realised that not all of my users are using the ESR version from the Software Centre (90.10.0), but have instead installed the normal version to their profile (ranging from 83.x.x to 101.x.x). These are clearly not being updated, and it's been flagged by security scans.

So, I'm looking for a way to remove them silently with a script that I can insert into the ESR deployment, and replace these unsupported versions.

Can anyone help me?

Hi,

We've GPOs in place for Edge and Chrome that set said browsers on all our Windows endpoints to open downloaded ICA files in Citrix Workspace.

I've imported the firefox.admx and mozilla.admx file along with assocaited .adml files, checked Github, checked through the GPO settings yet cannot figure out how to do the same with Firefox.

Is there a Mozila Firefox for Windows GPO ADMX setting I can use to control the "Firefox>Settings>General>Files and Applications>Applications" section to add "Content type: ica | Action: Use Citrix Workspace"?

Thanking you....

I have been tasked to have our Firefox auto update without user interaction. We have a small enterprise of about 2000 or so PCs but only maybe 300 use Firefox consistently. According to the GPOs it claims that it will update even when the browser is not open. I have this working fine on Chrome and Edge. You can see my attached screenshots that my GPOs are dropping down correctly to my VM. When I open Firefox and leave it open I can see that an "updated" folder is created in the Program Files>Mozilla Firefox. If I close Firefox the updated folder disappears and and installs the latest update. Once I reopen Firefox I can see that it updated. I need this to happen without the browser being launched, closed and reopened. I went into Settings>General and noticed that my update section is missing some of the update options that I see when researching. Automatically Install Updates and When Firefox is not Running options (see screen shots) are missing from my install. I am pretty sure this is why it will not truly silently auto update. Does anyone know where those two options are controlled from and how do I get those to show on my installs?

We have several servers with Firefox installed and automatic updates enabled to include "When Firefox is not running". However, our security scans indicate that the version is out of date. We have to connect to the box and finish the updates. The current version is at 103.0.1 and the previous version was above 100 (failing to remember exact version). Is there a way to ensure that Firefox remains up to date without connecting to the server?

Hello,

I want to download an extension using firefox policy templates. I put the location folder and extension id so that it cannot be deleted, but for some reason it doesn't want to install most of the times. The policy is added after using the gpupdate /force command and restarting the machine then open and close the browser. I wait 10 minutes for the policy to be configured on the computer and open the browser again and nothing happens. Also, the keys in the registry have the corresponding value type (checked in site https://admx.help/?Category=Firefox&Policy=Mozilla.Policies.Firefox::Extensions_Locked). But when I drag and drop with a mouse, the extension is installed and cannot be deleted. Can you tell me why does the extension not install when the policy is in effect?

I sent pictures from Group Policy Manager, Registry editor and showing that the extension can not be deleted after drag and drop with a mouse.

Thank you in advanced!

We have a customer using our SaaS solution running through Firefox 91.12.0 ESR. The web application we provide requires access to the camera on the local machine so we can capture a photo. We give them instructions and they configure their instance of Firefox to ALLOW access to the camera, along with several other adjustments (like allowing pop-ups, and no autofill).

However, whenever they restart Firefox the camera permission reverts back to the DEFAULT of Always Ask. The other settings adjustments we make, like pop-ups and no autofill stick around, but not the camera setting.

We've checked the PREF.js file in the Profile folder and that doesn't appear to be a problem. On our in-house machines we are running the same version of Windows and Firefox and cannot reproduce the problem.

The customer has recently applied the upgrade from an earlier version of Firefox ESR to 91.12.0. The customer has also imaged the PC and copied over to a large number of additional machines for use around their organization. This problem is causing a serious disruption to their deployment of the updated PC's as we work with them to try and troubleshoot the problem.

Any ideas on what to try would be appreciated.

Hello, Qualys is detecting Vulnerabilites on our Firefox ESR 91.12 Versions which were patched by MFSA2022-29.

It is showing Vulnerabilities because MFSA2022-30 lists CVE's for ESR 102.X and we are on 91.12.

Is there anywhere I can go to get a list of all Vulnerabilities on 91.X to show our Security team, I believe CVE-2022-36314 and CVE-2022-2505 are not present in 91.12 because they are not listed in https://www.mozilla.org/en-US/security/advisories/mfsa2022-29/ but need evidence

I have an issue on a Mac OS Server environment with home folders. The user's login to the MAC which authenticates to the Open Directory MAC server giving home folders to the logged-on users that reside on the server and not the local workstation. Users commonly use different computers to log in. What we're finding is that the users are increasingly getting the error message that a copy of firefox is open and firefox cannot open.

Removing the lock file solves the issue.

cd ~/Library/Application\ Support/Firefox/Profiles/ cd uniqueid.default rm -rf .parentlock

Is there a way to avoid this? We have the most current version of FF installed.

Some users in my organization have been complaining about FireFox location protection since the update to 103.0.2. We would like an option to completely disable this "feature". Our users are complaining about having to individually make exceptions via the shield icon and selecting custom and unchecking all boxes does not work for our use case scenario. Is there any option to disable this completely or are there plans in future releases to allow us a disable feature (like you used to have) or is the only solution to switch our users to Chrome?
