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 ?

I am really frustrated by the additional AI features coming to Firefox soon. How can I ensure I will be notified as those features are rolled out, and how can I turn them off for my personal browser? To clarify, I don’t want any of my data, activity, or history to be accessible by any AI, and I don’t want to interact with any AI when I use Firefox.

Since the new CEO of Firefox seems to be very determined to add more AI features to the browser that I've been using (among other things) specifically to escape AI slop, I will be considering switching to another browser. It will be disheartening to abandon the browser I've been using for years, but I value my personal data (and cpu) too much to let an AI handle it. I appreciated his words that it would be "Completely opt-in, you have full control, and if you try it and find it’s not for you, you can choose to switch it off", but I strongly believe that all AI browsers are inherently insecure. The first AI feature that I can't make completely disappear forever with one click will be my sign to switch browsers. Hopefully, Firefox re-thinks its approach and decides not to destroy the exact thing that makes it so valuable - the commitment to protect the users' privacy.

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've purposefully used the environment variable to disable the security sandbox.

How can I acknowledge and hide the persistent warning? Is there any about:config value for it?

Thank you!

As my title says, i manage to make my Tabs length to be as long as possible, i even manage to make it when i scroll with my mouse wheel one tab at a time, but after accepting to update Firefox, my tabs shrink when i play a video! or when i open a new youtube video in a new tab, that is only on youtube,

So how do i stop this? i do not need my tabs to shrink when i play a video

I know I am far from the first person to bring this up, but it is absolutely horrid how a browser that is supposed to be one of the better options for privacy is starting to integrate more and more unwanted AI "features". None of us want this, nobody asked for this. Generative AI (including LLMs like ChatGPT and its equivalents) is horrific to even try to get a correct answer out of. It's simply processing your input and guessing what you want to hear in its output. It doesn't give facts, it doesn't help the user experience, it just makes things worse.

Every single time a new AI...thing is added, I have to go find a way to turn it off. If this keeps going, I cannot see a future where Firefox is a viable option for secure browsing. If anything, it may actually become on-par with or, dare I say worse than Google Chrome.

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.

I keep getting annoying popups claiming to be from Mozilla Firefox. clicking on one takes me to a malicious website. Dismissing them only results in new ones opening. I am attaching a sample of a screen showing the popups on the right. I scanned for viruses and was told my computer is clean.

How can I stop this from happening?

I log into a secure web account, use user ID and password, go through 3 rd party verification and gain access.

When I logout it takes back to the sites Home page.

If I decide to login again by using the login icon the website immediately logs me backin with No requirement for user ID, Password or 3 rd party verification.

I am trying to determine is Firefox holding this information (User ID, Password and Third party verification code) and auto logging me in or have I not really logged out.

If I completely close Firefox this does not occur.

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

Firefox ver 145.0.2 (64bit)

there's no way I'll continue to use Firefox if AI is implemented, for years the reason I used this browser is because of it's safety and security and I believe if AI is implemented that will indefinitely go away. I will ditch this browser if this comes to pass.

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.

Hello, I choose to use Firefox because it does not have the amount of bloat and spyware that exist with other browsers. I fear that the recent call to add AI to the browser's functions will both slow the processing time down as well as increase the amount of spyware involved. I cannot see how this is a positive for the future of Firefox. All I can say definitively at this point is that should AI functions be added in I will be finding a way to never use them, even if it means kneecapping things for other functionality in the process. I will also be keeping an eye out for extensions or addons that remove the AI, as I have already with other AI online.

Hi i saw something saying the browser wanted to use more ai etc, is this true? Is there a way to opt out of these services in total if so?

I use firefox for the privacy and to avoid bloatware so itld be really disappointing if its now looking to use ai more in its services.

The continued addition of AI features in Firefox has shaken my belief that this browser centers privacy for their users. AI is bloating the Firefox service and creating my strain not only on my devices but our environment as more and more data centers are being built. This "tool" is often inaccurate, plagiarizes, and poses a threat to the security of our data. Firefox has always stood their ground to being a quality browser as other browsers got worse and more invasive, but with the addition of AI tools, it would seem it is eager to join the ranks of Chrome and Edge. If this is the trend Firefox intends to continue, then it is time I look for a safer alternative.

I realise any privacy or user control statements made by Mozilla are really a farce. One, there's no meaningful way to protect user privacy these days, not on the web. Trying would be a more accurate term. Two, the CEO is in control of the product design and he's banking on customer loyalty, betting on an outcome where people will just continue to use the product regardless of how bad the new AI features are or how much they contradict the company's supposed ethos. And it'll probably work for a spell, but here's the thing: free clones of Firefox already exist, and customer loyalty only goes so far. It won't be terribly convenient, but if I continue to see Mozilla adopt AI in its updates, I'll just switch over to something else.
