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.

When you open firefox private mode, it says leave no trace. Assuring users that whatever happens in their private session, stays in that session, but this is a blatant lie and firefox knows this. Go to any site that has cookies, or user login, or something similar. login into the site. Than simply remove firefox from ram. Now open firefox again, go to private mode, and go to that site. Most of the time, it still remembers the user. This issue has been present for far too long, not addressed, still pushed to the users that it is safe to use. Instead of warning the users, it is promoting them to use it by saying leaves no trace in this new update. This is unacceptable.

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!

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.

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.

I was prompted to install a .js file while on a website unrelated to mozilla organization. I was taking a work call and distracted at the time and was dumb enough to install it before I realized this was not a normal update. Should I uninstall and reinstall firefox? My McAfee blocked the script from "trying to hijack one of [my] apps"

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

To sign into Chatgbt I used my google account. Mozilla asks me "do I want to store info in persistent storage?" I click "learn more" about persistent storage. It takes me to a page that has zero mention of the words "persistent storage". That is a huge UX error. It says to me that really, you don't want me to know about persistent storage, and prefer that I remain confused and feel forced to agree to things I may not really want to, because you're making it difficult to understand what's actually involved. Not cool. Definitely now considering changing my browser after over 20 years.

On Windows 11 Pro, with the promotional McAfee app already uninstalled, the Firefox browser persistently presents what amounts to a Pop-up advertisement in the form of a fake new tab that remains in the background, unseen and left open even after one closes the browser session. How can this phenomenon be permanently terminated?

Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

Size: 695424 bytes SHA-256 hash: EEB242895F8ED48B43EAAA9ECA06C6DDE54425F8AE0E16200D2D46F839B9A540 File version: 145.0.0.327 Copyright: ©Firefox and Mozilla Developers Date modified: 16.11.2025 12:35 Original filename: firefox.exe Digital Signature: Mozilla Corporation

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

Size: 389248 bytes SHA-256 hash: E8DA5735FE1B5E92BA3636B8D17B5BEC0EA521DB6A8B5A52177FF3E8B2F60710 File version: 145.0.0.327 Copyright: Licence: MPL 2 Date modified: 16.11.2025 12:35 Original filename: desktop-launcher.exe Digital Signature: Mozilla Corporation

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

So, as I’m sure everyone has heard by now, the new CEO wants to make Firefox an “AI browser”. As a long time user, I think I speak for a lot of us when I say WE DON’T WANT THIS. In fact, the reason many of us were here is that Firefox was pretty much the last major browser not to give in to using generative AI for everything. I hope the CEO backtracks on this, or Firefox is going to lose a TON of users and money. Let’s go over the facts.

- Generative AI uses an unsustainable amount of energy and water, and AI data centers are responsible for a lot of air pollution. - AI tools are frequently incorrect, and lead to misinformation being spread. - Data is frequently scraped for AI training without user permission, and leaks are very common. This goes completely against Mozilla’s commitment to privacy, which was one of the big reasons I started using Firefox to begin with.

This announcement is very disappointing, and the CEO really needs to reconsider. Keep Firefox secure. Keep “AI” LLMs OUT.

Was prompted to download a program to Firefox before I paid my phone bill. I did not recognize the web address or name that was shown, and the account number from which recent payment was deducted did match any accounts I hold or held in the past. I cancelled the action immediately, without downloading, but am still concerned. I found nothing on the internet about this, just got a summation chat AI response that stated the phone company had no download/extension for Firefox. Has anyone had any experience like this or could someone shed some light on this?

Hello! Long time Firefox user here, grew up with a father working in IT security. He's mentioned this a few times before, but now we've both really noticed the push towards using generative AI in roles in IT where it's really unsuitable, and honestly quite a risk to security and privacy, not to mention quite a waste of time having to fact check things properly because I cannot even be sure that the first result in a Google search for "how far away is the moon" will be correct. We're quite concerned that Firefox is following suit, especially with the new CEO evidently not understanding some of the fundamentals of why this browser has such a dedicated user base. Just wondering if saving the money by not having to hire competent, trained professionals who can provide the human touch needed to run a browser is truly worth eroding Firefox's reputation of being the genuinely good alternative to Chrome? How long before the AI stops being optional? How much of the code is going to end up written by some language learning algorithm and passed off as safe? If this push is to continue, what alternatives does anyone in the community suggest? Thank you for any responses from both myself and my father :-)

In settings, it says Your browser is being managed by your organization. I clicked it and it led me to the policies page. In there it says Policy Name- Certificates, Policy value- ImportEnterpriseRoots and then true. I neither work in an organisation, nor I have any antivirus in my computer. Why is this happening?
