I had switched to Firefox some time ago because of the privacy-invading AI that Google and Microsoft were implementing at the time, and it appeared Mozilla had their consumers' interests in mind when it came to privacy and performance. I suppose even they are willing to shoot themselves in the foot with the market failure that is generative AI, despite the recent reports about Copilot's abysmal sales proving that this maneuver is incredibly short-sighted.

Not only are these AI "features" enabled by default upon updating, the options to disable each of them are all hidden away in the about:config page. On top of that, having these options enabled leads to worse performance overall, and the breach of privacy inherent to these features is quite worrisome as well.

The best step now is to remove these features completely. If Mozilla won't remove them, they should at least have them disabled by default, making them opt-in as opposed to the opt-out situation currently in place. Perhaps they could be listed as proper options somewhere in about:preferences so that people don't have to comb through the about:config list?

I know I would appreciate not having to switch browsers again, and I'm sure plenty of users would like to have their privacy respected as well. We don't want to see this browser become as terrible to use as other big-name brands. If Mozilla keep pushing these invasive features, we will find something else to use.

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

Hello there,

I am new to Firefox. I recently installed it on Android with the latest version (I believe it is 143) and while playing with the settings, I found the "Private Lock Tabs" feature. However, even after acknowledging it with my fingerprint, I can switch back and forth to normal browsing without it ever requesting my fingerprint again, and my private tabs remain visible and are never hidden. I have tried uninstalling/reinstalling the app and turning on/off the feature but it doesn't seem to work. Any help is appreciated!

I accidentally clicked on a site that was supposed to be a game review site that I found on a Bing search. Now I get pop up ads for fake virus programs whenever I run Firefox.

I ran a scan with Mallware Bytes and Microsoft Defender and both scans came up clean.

I am including a screenshot of the popups.

Any ideas?

Thanks

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!

Why is Firefox leanining into this ai nonsense? Its antithetical to privacy amd security, it slows down the browser for no benefit, so i end up jumping through hoops to turn it all off. If I wanted AI, I'd be using chrome or edge. I don't want AI. If firrfox continues to shove this ai onto us i'll have to switch again. Its self sabotage at this point

Hello,

I downloaded the Firefox installer from the official website (https://www.mozilla.org/ru/firefox/download/thanks/). After downloading, I checked the SHA256 hash of the file: 051deb55cf9579e1f9b3bad71ec4a390353c568ef21849671953d08343b4e890.

However, this hash does not match any of the hashes listed on the official page: https://ftp.mozilla.org/pub/firefox/releases/133.0.3/SHA256SUMS.

Additionally, a VirusTotal scan flagged the file with a potential virus alert.

Could you clarify why there might be a discrepancy in the hash and whether this file could be legitimate?

Thank you.

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

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 ;-)

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?

For 2 days now I am overwhelmed with Firefox Security alerts about everything from Trojan Horses to system warnings. I know they are fake, but they are driving me crazy. Can anything be done about them?

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’ve dowloaded firefox. i’ve read the tutorials for browsing setting private browsing but the “masked symbol never appears to click. I tried to download from “App Store” the Private Mode but indicated I had it and back to square one. I like it on my desktop bur can’t on my iPhone 11 Pro Max updated to highest release of IOS

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.

Hello I have an application that shows forms where the input fields are inserted on table columns. When the column contains two fields sometimes the second field is showed not in the same line.

It must be said that the second field is added after the creation of the form.

Whit Chrome and Edge the form is showed correctly. At thislink the behavior can be seen. Thanks

I'm sick of having to turn off ai features in every freaking thing, if the product was any good you wouldn't have to push it so hard!

This is bad for my data security and privacy. Bad for the environment. Spreads falsehoods. And promotes plagiarism.

I'm already starting to look around for other browsers so I can switch over and delete this account if you don't stop this garbage.

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!
