Firefox Community Forum

Why am I receiving repeated warnings from Malwarebytes about blocking every-day websites due to a "Trojan"? The sites include Gmail, Ancestry.com, Newspapers.com and others.

The report warnings are being generated by the Malwarebytes program on my PC. They are confusing to me. I am running Windows 11. The warnings are being logged by the Malwarebytes program in the "Web Protection" section of its "Detection History" web page. In every instance, the log reports are the same: in the URL identification column there is no identification of the URL, only repeated instances of "N/A"; the IP address is identical for all the warnings; the port is always "0"; the file column alternates from "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe" to "System" and back again to "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe"; in the final column of the log, the Date column, the warnings began last evening, Monday the 12th, at 6:50 p.m. and have now extended to to a total nine warnings.

Even as I was writing this communication, the Malwarebytes warning popped up on my screen, telling me that this website and this web page are blocked due to the presence of a Trojan.

Is my PC infected? The Malwarebytes "scan" reports no "detections." I am at a loss.

Good Afternoon

I have exhausted all possible restrictions for Fire Fox to sync with McAfee I have gone to Windows Firewall the inbound rule is blocked if rules don't apply Fire Fox and McAfee are both enabled on my personal computer as private The McAfee keeps showing a setup window for both Googles and Fire Fox At one time all 3 of my browsers were setup and then it drops as a change in default browser is selected

Hello,

Recently I have noticed 'Your browser is being managed by your organization. - That being ImportEnterpriseRoots' appearing in settings. I have seen this mentioned by others but as of yet I cannot see if it has been sorted yet. I have uninstalled and it went away, but it has since returned the following day. I Do not have any other anti-virus on this laptop other than Windows Defender so it cannot be that. I will not be using Firefox as default until this is gone, or at the very least know that its safe.

DO NOT COPY AND PASTE! This is not written correctly! Someone please help with this or correct the code. I tried different ways to do this and nothing works ---- I am beyond frustrated with it.

Security features warning

You may see a warning that “some of Firefox’s security features may offer less protection on your current operating system”.

The sandbox in Firefox makes use of unprivileged user namespaces when creating new processes for enforcing more security. This can be considered a security risk, therefore some Linux distributions have started to restrict its usage and only allow it to work where there is an AppArmor profile.

Such profiles can only cover a limited set of installations paths, including Snap and Debian packages. They cannot however cover some other use cases, such as tarball installations as well as local development builds.

To create an AppArmor profile for Firefox:

In /etc/apparmor.d/, create a file with the name firefox-local

In the file, add the following:

1. This profile allows everything and only exists to give the
2. application a name instead of having the label "unconfined"

abi <abi/4.0>, include <tunables/global> profile firefox-local /home/<USER>/bin/firefox/{firefox,firefox-bin,updater} flags=(unconfined) {

   userns,
   # Site-specific additions and overrides. See local/README for details.
   include if exists <local/firefox>

}

Replace <USER> with your Linux user name. This assumes the Firefox install is at $HOME/bin/

Once you have saved the file, run sudo systemctl restart apparmor.service in the Linux terminal.

Hello.

Everytime I open a new Firefox window, I get this warning from my antivirus:

Suspicious connection blocked 8 minutes ago

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to sync.contextualadv.com. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Usually, when I see this happen, the company fixes the issue within a day or two, but this has been occurring since at least 4/9/2025. This warning occurs regardless of whether my browser is logged into it's Mozilla account or not.

How to get rid of ImportEnterpriseRoots, so I can control my own computer & update Firefox? (Update options are not shown under Settings- General tab any longer for me due to the message showing "Your browser is being managed by your organization"--ImportEnterpriseRoots"? I am the only user on my computer & definitively not part of an "Organization". I found some help online that was way too technical for me. Thanks!

I have attempted to sign in to MyHealtheVet.gov 3 or 4 times over as many hours. Every instance has encountered the same message "Secure Connection Failed. This is the Verterans Administration website and find it hard to believe their website is not secure. I'm not a computer geek, far from it, hence utilizing this method of contact. I have been notified by email that I have a secure messaging message on the VA site that I am unable to access/ Thanks in advance,

Well I've been chasing this problem for about a year. Things I have done. 1) reinstalled firefox 2)reinstalled windows 3)attempt to remove the ImportEnterpriseRoots flag via Regedit. (Mozilla does not even appear in in the policies folder) I Suspect this has something to do with having logged into my firefox account on a shared work computer, and the sysadmins subsequently removing the ability to use personal firefox accounts on these computers, to the point of not even being able to logout of the account.

It just keeps coming back. I only have MS Defender for security so I don't think its security software causing it, and I do not believe a virus/rootkit would survive several formats and reinstalls.

For the last couple of days, when I am using Firefox I am bombarded with security alerts ranging from "System Alert" to "Viruses found (3)" to "Trojan Detected". The icons shown are Windows, McAfee, Google, and others. Mozilla Firefox with its logo are in small print, top left corner. I am usually asked to click; I do not click! I scanned my computer (Webroot) and the scan comes back clean each time. The last line in all of these is "via d04e3a0hubcc73bbgvsg.chainintegration.co.in" How do I get rid of these? Thanks for any help. Susan

How do I remove "firefox browser being managed by your organisation" . I have looked at several posts and don't understand a word of it. I recently re-installed Firefox and lost all my passwords but still have bookmarks, every time I turn off firefox it forgets my account sign in, I then get an email to say I have signged in on a new device. I suspect it is the Norton 360 security software. Please can someone explain in simple terms how to remove it. I have tried contacting Norton but their support is worse than Microsoft.

i was trying to access shopify and its protect behind a firewall and it was asking if firefox as access to the internet or its being protect by the firewall how would i go about using this website if i don't know how to go about this

I'm getting alot of messages several times a day for a week now. Just about all of them are with the Firefox logo but I'm pretty sure it's not Firefox.

Things like phone is corrupt.  Delete certain files.  18 viruses found.  I have some screen shot of them. How can I make this stop?
 It's constant and annoying.

OK, this is getting to the point where I no longer want to use Firefox. I have had trouble in the past where if I went on Edge for some reason and logged in to my email, when I returned to Firefox I was logged out of all my Yahoo powered email accounts. When trying to log on I would receive the attached message and it would take hours, and sometimes days to be able to log on. Even when I was logged on to my main mail account, I would not be able to log on to the other two accounts. The last time this happened is when I realized it coincided with me logging into my email on Edge, so I have not logged into my email using Edge since then. Unfortunately that was just a coincidence, because it happened today and I hadn't been on Edge since I posted my previous question in February.

I am always logged into all three accounts, but since this happened two months ago, I only logged into my main account and one other on Firefox, but I have only accessed the main account since logging in to both of them. I only accessed the other two accounts on my phone, which was fine, but I sent my phone to get the fingerprint sensor repaired so I'm using my wife's old iphone now. Don't get me started on how this phone sucks, but I needed to access one of the other accounts today and I don't have either of them set up on the Yahoo app, and I didn't want to take the time to set up the one now when my phone should be back in my hands in a couple of days. I came in the house and fired up my computer again opened my email and switched to the account I needed and surprise! I was logged in. I did what I needed to do and tried to switch back to my main email when surprise again! I received that same dreaded message.

I have been trying to log in to my account on and off for about five hours now, and I'm about to toss my notebook across the room. That would leave me without a PC though, so I am forced to use Edge, but for how long? I have posted on Mozilla support many times in the past for different things, but I have never actually had anyone from Mozilla provide an answer to any of my issues. Is that because this is only a community forum? Does anyone that works for Mozilla or Firefox actually access this forum and see these questions? If it's only a community forum, where do I get post my issue to be able to receive answers from the people that make Firefox work? My last post in February had 17 views, seven others that have the same issue, (so I'm not the only one), and no replies other than my posts adding content because you can't edit your original post. Evidently the people that have an answer to my problems haven't seen it.

Maybe I selected the wrong topic? I don't remember what topic I selected two months ago, but I selected passwords and sign in today, so hopefully it's not the same topic and maybe I'll receive some input this time.

Thanks in advance.
