Hello everyone.

We are using a software in my company that runs a local server with a self-signed certificate. In order to access the software right now we need to instruct the users to manually bypass the warning page for potencial security risks.

Is there a way to use an autoconfig or policy to automatically add the exception to that specific URL? I see that copying the cert_override.txt file in users profiles will add the exception, but I'd like to avoid that. I've also looked at a question with a similar problem here, but I couldn't get this specific solution to work on my end (Firefox ESR 91): https://support.mozilla.org/en-US/questions/1287443

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.

There is a certificate for an internal website that FireFox is saying is not valid/secure and it makes you add an exception. However, if you use IE, Edge or Chrome it loads fine with the valid CA Certificate. I've cleared all data (cache/etc...) and it hasn't fixed it. Hopefully someone has a fix for this?

Getting "SEC_ERROR_UNKNOWN_ISSUER" for the certificate and its saying:

   Peer’s Certificate issuer is not recognized.
   HTTP Strict Transport Security: false
   HTTP Public Key Pinning: false

Firefox starting extremely slow when custom homepage GPO applied

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);

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 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?
