Firefox Community Forum

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.

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.

I'm sending this from my phone. My desktop FF (Win 10) suddenly displayed a black wireless globe type icon called Prox-Media pinned to my taskbar. I can't find the app on my system, though, but the full path leads it to a firefox.exe file. Before my brain kicked in, I'd clicked on the icon right after noticing it, and Firefox came up with the attached error message displayed.

"Prox-Media" comes up nowhere in my searches - not as legit, not as a virus - just no results. Can you help?

I have a paid AVG account and I ran a deep scan but it found nothing.

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

every download gets stopped with "This file contains a virus or malware", have to click on the file, then click "allow download" every time!

I check the file with my antivirus and it finds NOTHING!

I clicked on a link in a forum site - pentaxforums.com - that should have pulled up image from a private web site but I think the url has been hijacked, the image didn't appear and instead the browser started pinging alerts. I have run avast anti virus and malwarebytes, these found suspicous malware (trojan, key clone) and rebooted, but these alerts still keep appearing, however I am wondering of the browser alert system itself has been compromised. See screenshots. if I click on one it seems to be trying to go to a suspicious url. any advice appreciated Marcus Brown

I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

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 ;-)

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

Also McAffee notification with all these popups stating that my McAffee protection expired yesterday - I have never had a McAffee notification for a virus or pair for protection from them. Popups are happening every 10 seconds continuously! looks like about 20 or more popups describing different problems with 20 digit numbers and letters as a serial number of the problem!

After all of those years, am I witnessing now that FF literally failing?

How could it become mysterious by that it lets user's location leaked to github even though: - third-party HiFi company VPN is active and in OpenVPN UDP/TCP, Wireguard, IPv6 On/Off, etc... - No bookmark to corresponding website - Cache and website data were so-called cleaned, - Other browsers don't give that symptom, only FF - No related plugin, out of only 3

it's impossible to find out how it lends to the language and region query of this website every time after cleaning. Is FF getting closed app?

Is that a no-way-to-explain effect of language models' evolution is exponentially higher in every 4 months after two years?

I did some research recently on some travel sites.

Today, while trying to research which tab was doing DNS queries to SnapChat (which I never use) I learned about `about:processes`. I found 5 "hidden" tabs from various travel sites (some of which I never visited) running in the background. I did not explicitly hide any tabs.

WHY IS IT ALLOWED FOR SITES TO KEEP OPEN HIDDEN TABS AT ALL WITHOUT TELLING ME ABOUT IT?

This is not conducive to trusting Mozilla.

There must be a way to turn off this popup off. This is REALLY annoying when it covers a password box and to remove it i must click outside it and I lose focus on the password box. If you must put he box there then at least leave the first part of the password box clear so I cab click on it and not have to click again to get the focus back.

What happened to Firefox's permission's page? There's so few options now. I'm being harassed by websites to give them permission that should be blocked across the entire browser. I'm autistic and sensitive to popups/interruptions/distractions. So most permissions I simply had off for everything, because I don't want to be asked anything. I don't want to confirm anything. I don't want any popup of any type. So I turned everything off and it was good. (except blocking cookies of course)

But now sites are asking me again and there's no way to blanket turn off everything. I see I can press "Ctrl+i" to bring up specific permissions for that site, but that's not good enough. I specifically need permissions blocked for sites I've never visited. Needing to visit the site first completely defeats the purpose.

The permissions listed in the settings isn't all of them. How do I turn off ALL permissions for ALL sites. I can turn on specific permissions when I want them. Essentially, how do I recreate functionality that used to exist but was removed from us for whatever reason.

Also, it's a huge security hole! I'm a senior full stack developer. Asking permissions for a user is a great way to fingerprint them. If I accidentally hit "yes" to a few key permissions, I can be fingerprinted. Another reason I should be able to blanket ban these permissions. I just want my browser to be a browser. These permissions do nothing for me but make the experience worse.

Last few days I've been getting this popup:

Attention!!! Click to turn on the antivirus

or

Attention!!! Click to scan the device

obviously some phishing or something. How can I get rid of it?

WHAT THE HELL IS THIS???

EXPLAIN PLEASE IF NOT I AM DELETING FIRE FOX

Some extensions I use have been updated and now ask permission to "Access your data for all websites." What is the scope of this access? Can an extension which facilitates video downloads see my bank password? Can it access data for sites in a different Firefox container? Can it access sites which I use in a different browser? Can it access data for sites which, on my system, are only available to a different user? Thanks for any clarification. [I am running Firefox 149.0 under Kubuntu 24.04]

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

At the top of my settings it says: Information: Your browser is being managed by your organization.

What does this mean? It's my personal laptop, I bought it myself and I don't work for any organization.

Thanks for your help. Nancy
