We are deploying Firefox installed via the v122 binary on Ubuntu 22.04.4 Server w/ubuntu-desktop-minimal --no-install-recommends (we need to have no-user-interaction install). We are using an Ansible playbook to copy over and unarchive the tarball, then create a firefox/distribution folder in the install directory and copying a profiles.json file to said folder, links the install directory to the /usr/bin/local directory, and setting firefox.desktop as the system default browser.

Using the instructions from: https://mozilla.github.io/policy-templates/

What we are hoping to accomplish is the user who has never launched Firefox will click on a link in an application, which will launch Firefox and go directly to the requested page. As it stands right now, the first time a user clicks the link, it launches firefox and shows a start page. The user must then close this window, and click the link again. This brings up a "Use Firefox as the default browser" prompt, which the user must accept, but then does not display the link. The third time the user clicks the link, the requested page pops up, and works from this time out.

We would like to have this be a one-click experience for the user. Looking at the options in about:config after getting firefox to launch, it appears firefox is not getting the options from the profiles.json file. Are we missing something about placement of this file? Missing some lines? Should we be using AutoConfig instead? Thank you for any assistance!

Why isn't firefox ESR 102.1 available for download via this link, it still downloads 91.12 which has vulnerabilities. https://www.mozilla.org/en-US/firefox/enterprise/ I found it after digging around but it was a hassel.

We use Firefox ESR for along time in our organisation but with the last update, a specific page wont redirect to the ADFS page. In the latest normal version of Firefox it works and also other browser but not in ESR.

The webpage is https://rx-base.nl/ and https://preprod.rx-base.nl/

We are using the latest version of ESR. It gives a blank page with in the console a error:

Uncaught (in promise) TypeError: Fout bij het oplossen van modulespecificatie ‘@rxbase/root’. Relatieve modulespecificaties moeten beginnen met ‘./’, ‘../’ of ‘/’.

Please advise on what to do.

Hello Guys,

in our network we have several Fritzbox Routers which we remote administrate. If we connect to the routers with Firefox V115.2.0 we get a warning message - because it´s a Fritzbox self-signed certificate and cannot be validated. No Problem - everything okay with the message. But in Firefox 115.2.0 there is no advanced button that lets you go futher to connect to the website. With Version 102.14.0 ESR the advanced button is there. The webinterface works fine with Edge and Chrome (with warning but with advanced button to continue)

Is this a bug?

Best Regards, Michael

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?

I've successfully added all the admx profile settings we want for our deployment except I can't seem to get right syntax for adding multiple sites to the exception list. We've successfully blocked all urls in the block oma-uri but for the exception it only shows a single example not multiple. (https://github.com/mozilla/policy-templates#websitefilter site) OMA-URI:

./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/B_WebsiteFilter_Exceptions

Value (string):

<enabled/> <data id="WebsiteFilter" value="1*://*companyurl.com/*"/>

this works.. all internal sites are accessable. what i want to do is as well make these sites avail as well *://company.sharepoint.com/* accessable and

• //login.microsoftonline.com/*

I've looked at https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns but i can't seem to find proper format for multiple that doesn't cause line to either be ignored or errored out

any assistance would be appreciated

Hello,

My operating system is 64 bit Windows 10. I perform many membership transactions through Semrush.com. But I think semrush blocked me. When I try to log in or become a member, I receive a "Your Request Has Been Locked" warning. I uninstall Firefox 64bit and install 32bit and the problem disappears. But I want to use 64 bit again. For this reason, I also did a thorough cleaning with uninstaller programs, but to no avail..

I think Semrush 64bit firefox seems to see something in my program and banned it. How can I change whatever it sees so that it doesn't get blocked?

When downloading Firefox ESR via the website for macOS (https://download.mozilla.org/?product=firefox-esr-latest-ssl&os=osx&lang=en-US) one still receives the old 91.13.0 version instead of the current release 102.2.0. Can you please fix this?

I keep getting this error. I reinstalled mozila firefox esr, but the error seems to persist. What could I do to get rid of this error that constantly appears at a certain time interval?

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.

Hello,

Toggle button yahoo setting - desktop notifications, not working

I am facing this problem only in firefox windows 11. Sometimes it works but rarely and inconsistently. I have tried the suggested solutions..

At your disposal

Environment:

• Version: 102.3.0esr
• Build ID: 20220912135840
• OS: Windows_NT 10.0 19044

Issue: I had Firefox window 1 opened in virtual desktop 1, then I switched to virtual desktop 2 and open Firefox window 2 there. After using window 2 for some time, I switched back to virtual desktop 1 and found Firefox window 1 was gone. I checked `about:support` page but found no crash report there. I don't know what's going wrong.

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.
