Firefox: форум сообщества

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.

seems that after Firefox 150.0.3 (20260511200624). I cant access locally deployed servers that are not secure. the Firefox forces https when hitting http://localhost. I've tried to disable the HTTPS setting altogether. Even in developer mode it still overwrites http to https.

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

woke up after doozing watching a yt video and on my pc i couldn't oppen firefox and it kept crashing so i just booted my pc again

After that i could open firefox but it had a yellow simbol on the three dot setting sections that stated "new tab has downloaded a new component"

i searched online and they said it could be an hijacker i refreshed firefox and run an anlysis with the base windows antivirus

the antivirus say's i'm clean but i still kinda unsure:

  was it really an infection? i ask myself if it could be just a firefox bug i checked extention before refreshing and the only one was 7tv and nothing else

  if it was an hijacker how can i fully know if i'm clean? what better steps can i take?

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.

Seriously Mozilla.

First with ramming AI everywhere in Firefox, now a browser VPN, why?

I do not want a VPN the web browser that I didn't ask for or other features you think people need without asking.

Corporate and business users would not have a bar of this either.

Enough!

Remove this from Firefox please in the next release.

In the meantime, tell users how to disable this VPN via the Settings and "about:config" so this never gets turned on.

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

Some users are abandoning Firefox because of the difficulty of protecting against Firefox fingerprinting. Therefore, I strongly recommend adding an option in the settings that allows the digital fingerprints to be made random, or at least, if it is difficult, to make the fingerprints indistinguishable. This will help improve Firefox’s reputation and the privacy of its users. Love you all 3:

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?

I use Firefox on Linux-Mint. When I check that I trust the digital certificate "Warsaw Personal CA" this information is not saved. Every time I restart Firefox I have to check this option.

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 ?

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?

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.

Max

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

Hi, When connecting to a HTTP:// site, when you enter your username in the username field, Firefox prompts the user with: "This connection is not secure. Logins entered here could be compromised. Learn More".

How can I turn this message off?

We are running Firefox in kiosk mode in the browser (on a Windows 11 PC), and they are logging into an HTTP site using a touch screen, but when they click into the username box, they sometimes miss touch where to enter this username and instead touch the link mentioned in the message. This then takes them to the Mozilla homepage, but because it is running in kiosk mode, they are unable to navigate back, and they are prevented from closing and restarting Firefox. This is why we need to turn the message off.

I assume Mozilla developers are working on this?

Quote from the article

"Its capabilities are a step change from the previous best models. Given the challenge of attacking the Firefox web browser’s JavaScript engine, Anthropic’s previous most powerful model Opus 4.6 succeeded just twice, compared to 181 times for Mythos. Most worryingly, the team found that engineers with no security background could use it to develop successful attacks overnight."

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 :-)
