Firefox Community Forum

I was asked to 'Allow Chatgpt.com to store data in persistent storage'. Would that add on the risk of having my data being more exposed and kept by stakeholders not of my own choice?

I attempted to put in an address of what I thought was a website today on mozilla. I soon found out that it was not available or a proper website.

Now I am getting alarming notices with heading Mozilla Firefox all via what looks like an Indian website, saying 1. Click to secure your 2. Trojan detected Fix it now. 3. Critical Error. Click here to remove them.

I have not clicked on any part apart from the x top right to remove the notifications. I can send photos of them

I have scanned with my Windows Security repeatedly and nothing.

PS. The messages are obstinate to remove and it takes effort to x them.

Regarding the new built in Firefox VPN. If I have Tabs open and Enable the VPN on a New Tab, does it then affect all previously opened Tabs, only the New Tab, only the New Tab and Tabs opened after that initial New Tab, or ? Also, is there a Meter Display or similar so I know how much of the 50GB VPN allotment has been used or is remaining ? Thank you, very kindly ...-- J V

Hi,

I noticed that in the latest release (I tried both MacOS and Windows 11 ARM versions) that the "network.cookie.sameSite.laxByDefault" is no longer enabled, and cookies set by applications without specifying the flag, are not set with Lax and are sent in cross-origin requests. Could you clarify if this is intentional and why the change has been made?

Thanks

Firefox detected a potential security threat and did not continue to myccp.ccp.edu. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I tried to open to a site WWW.RAFY-A.com this morning and got an alert it was not available, but, I am now unable to dismiss or close the following ATTENTION! messages. I did click on the "click here to secure your data! on the top two now it shows a yellow triangle which I'm still unable to close or dismiss. Could someone please explain how to get rid of these. I ran Dell Support Assist but I do not have a virus option. I have not rebooted yet as I wanted to clear this up first and then reboot. Thank you. Irene

I can't delete the malware "Startfenster. I tried to find help with "Google"-Search. Without any success! This malware exists for me in "Firefox" only. Other browsers are not affected. Perhaps anyone can help me... Thank's!

I have an old Mac desktop computer and use firefox as my browser. I go to hotmail and click on and up comes my inbox. I click on an item but nothing opens. then I get a message up top saying firefox prevented the opening of one or more pop up windows. I have changed my password with microsoft. That has not improved things.

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

Hi, I am using Firefox exclusively for my work Claude account, I only check my usage on it. Today, I noticed Firefox silently installed a webapp under $USER/AppData/Roaming/Microsoft/Windows/Start Menu/Programs, and it has a Claude webapp, which I neither click any install or add to my menu. I found it extremely concerning in terms of privacy, and I am wondering if any other people have similar experience.

Hello This evening as I was going to pay for a book on a site well known to me, I notice that I don’t see a lock to the left of the address. I read your page 'Mixed content blocking in Firefox' after seeing that its little French sister was not up to date and it seems that it is the version of Firefox installed tonight that is behind this big change. Even my bank’s site no longer shows padlocks and it’s destabilizing. Why such a change without explanation??? I only read information about the split view in the same tab (which seems very useful) but nothing about this disappearance of the lock... Can you confirm that it is indeed the version from tonight 27/03/2026 that made this change at first glance worrying.

Thank you in advance and have a good day.

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

Tonight I was roaming around my Firefox settings looking at something else, when I noticed this AI piece pre-checked. Why is FIREFOX, who is supposed to be for privacy and security, authorizing an update that automatically choose AI? Not cool Mozilla. Not Cool. Anyone else have this? and yes, I've already fixed it ;-)
