I am a Cyber Security Specialist and System Integrator (www.techwareusa.com and www.cybersecureusa.com ). I have developed a pretty good Cyber Security Stack with the exception of one chink in my armor. I have been running the Stack on my Clients systems (about 100 total) for over two years and have had only one breach. That breach was caused by the Client not following my suggestion (read any popup and don’t just click through it). He does now.

Part of my Stack is Firefox which I like a lot except that your cyber security leaves one thing as an exposure.

If one were to browse to a poisoned website (namely one infected with malware of some type) and click on an inserted link, malware is automatically downloaded and installed. Firefox does nothing to stop the system from being infected. This kind of website is one that pops up with a big red screen saying your machine has been infected with a “trojan” or some such. Do not attempt to turn off your system and call Microsoft Support at xxx-xxx-xxxx” (often an 800 #). Indeed, the browser is locked and can’t be closed from a normal action. (When I install Firefox, I setup the security features for my Clients including telling it to block pop-up windows and Warn you when websites try to install add-ons in the Privacy & Security, Permissions section. I have my Clients systems under my control via Splashtop Remote Support into my office. If the “Tech” hasn’t messed up my Splashtop install, I will go in, use Task Manager to shut down Firefox and then clean the system. If the “Tech” did mess up my Splashtop install, the system will have to be sent to me to fix. I have Clients in several states across the southern part of the country.

If the Client calls the 800# the “tech” will remotely access their system and totally messes it up with registry entry’s, replacing files with corrupted versions and such actions. All of this to raise the cost to my Client. They will charge the Client about $700 to $800 but also they will get the Client’s Credit card information to sell. The Client will then call me and often the system is so messed up that I have to reload the OS and missing applications plus my time and the total cost to the Client is often well over $1,000.

I have been looking for software that will block these poisoned websites. The only one that I have found that looks like it will work is Threatlocker. While a good product, the company has its head in the wrong place as far as setting up resellers. I am a reseller and have been in business for over 28 years and have had many vendor relationships. These folks want us to sign both an End User Agreement (that makes me responsible for the way that my Clients use their software) plus they want me to sign a Partner Agreement. In my mind I cannot be both and certainly will not agree to be the end user.

Back to what I am asking help on is the automatic install of the malware off of the poisoned website. Perhaps a browser “setting” to ask for an override button option to be able to install software on the system. If I chose this in the Firefox Settings it will take an action on the part of the user to override the automatic install. In fact, if we could add to the option a number of times (and maybe a message, like CALL BILL before you proceed) that the override button has to be pressed to do the install. The more I can get the user to think, the better it will be for them and the more they will appreciate Firefox and me. No other browser has any feature like this.

Mozilla's website states:

"Numerous features of the kiosk mode are configurable through policy or command line parameters when launching the browser."

However, other than a single example to run kiosk mode as a private window, it doesn't seem to provide any information on how to access such configuration. I couldn't seem to find the information anywhere else either.

How can I configure kiosk mode? Preferably via the CLI, but I'd be interested also to learn what is meant by "configurable through policy".

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);

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?

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

Hi all,

we are using Mozilla Firefox ESR in our enterprise environment.

Is there a documentation which URL's Firefox uses when (Mozilla Maintenance Service) when it tries to update his version ?

We have tried with following URL's on our Firewall:

aus.mozilla.org aus2.mozilla.org aus3.mozilla.org aus4.mozilla.org aus5.mozilla.org download.cdn.mozilla.net archive.mozilla.org ftp.mozilla.org

It is finding the new version, but when trying to download the update it fails.

Thank you for any help on this case.

Permission Problem with Camera

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.

We use GPO to push out our Firefox homepage and bookmarks. I get totally different results for each user, some will make changes right away if I add a new book marks, but they don't see older ones?

I decided to build a few test machines (we don't have time to build a dev envir) and it applies the GPO for the home page but not the bookmarks, I can see the book marks in the registry even but nothing on firefox. Anyone have a guess?

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?

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.

Hi,

I've been tasked to make some changes to the way users deal with logins and passwords in the office. So, in short, one of the issues is this: is there ANY way to disable (I'd say "hide" is more accurate) the about:logins page on Firefox?

  • pref.privacy.disable_button.view_passwords (with a lock pref) in autoconfig only disables the "View saved logins" button in Settings.

As for policies:

  • a few policies for blocking about: pages do exist - BlockAboutAddons/Config/Profiles/Support, but can't find one, say, "BlockAboutLogins" or something like that.
  • PasswordManagerEnabled set to false disables the password manager completely, including about:logins, password autofill is disabled as well - not what I need.
  • WebsiteFilter, as expected, doesn't treat about: as a protocol, so it can't be done there either.


Any help is appreciated. Thanks in advance!

I am deploying Mozilla Firefox using Intune. The application is deployed no problem but there is always the error in Intune portal. I was told that Mozilla Firefox has custom return codes to indicate post-installation behavior. That is why though the application itself is installed and works properly on the device, Intune portal does not know the status of the installation and gives the error. This error causes a lot of issues to the further application management. Dose any one knows what those codes are? Or maybe can point into the correct direction on how to get them. Thank you.
