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.

My cat jumped on my keyboad and Firefox detected 'unusual activity' She probably hit a combination of keys which lead to said activity. Instantly, I had to verify whether I was a human. I did, but really, it was my cat. Neither my cat, nor myself have bad intentions. I just thought Firefox security should know that these things might happen.

I hope that my cat's activity didn't compromise my account. Maybe 'unusual activity' should be less strict, though I do understand that Firefox must be vigilant. Maybe it would be a good idea to let users describe what happened, before sending Captcha?

What or who is Certification Manager? I have never heard of 99% of those listed in my settings. Why is this necessary? I would just like to go in there and delete every one of them!

I don't know whether I can trust three warnings I've recd, ostensibly from Mozilla Firefox: -Attention Click here to secure your data. -McAfee: 3 viruses found, Hard drive is infected! Remove viruses via ...(but I don't have a McAfee account) -McAfee license has expired. Click here to stay protected online? via ....

I have run MalwareBytes (basic free account) and it found nothing.

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.

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

Hi,

Microsoft and Google are part of Anthropic's Project Glasswing but Mozilla is not. I am concerned about Firefox security if Mozilla in not being included. What is your plan to participate? Do I need to switch browsers in the meantime? Please advise. Thanks.

Cheers

Hi,

Why private window is the same as general window browse? It should be different, yesterday was different, when I created a new account, this new private window change it to the public window, are they any bugs? Can you fix it? Thanks.

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

Hello This evening as I was going to pay for a book on a site well known to me, I notice that I don’t see a lock to the left of the address. I read your page 'Mixed content blocking in Firefox' after seeing that its little French sister was not up to date and it seems that it is the version of Firefox installed tonight that is behind this big change. Even my bank’s site no longer shows padlocks and it’s destabilizing. Why such a change without explanation??? I only read information about the split view in the same tab (which seems very useful) but nothing about this disappearance of the lock... Can you confirm that it is indeed the version from tonight 27/03/2026 that made this change at first glance worrying.

Thank you in advance and have a good day.

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]

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.

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.

When the AI chatbot is enabled in the sidebar but "collapsed" -- the tool not engaged -- is any data sent to the chatbot provider? Can the chatbot be collecting data while not engaging with the user? Or is context sent only with prompts and limited to the tab that is open?

What sort of sandboxing is enforced by Firefox?

I am getting repeated pop up "alerts" from Firefox, McAfee and others about Trojan Horse and other viruses. I did not click on the links offered. How do I stop them from coming?

I can't delete the malware "Startfenster. I tried to find help with "Google"-Search. Without any success! This malware exists for me in "Firefox" only. Other browsers are not affected. Perhaps anyone can help me... Thank's!

When accessing important accounts on websites, like financial websites, I've always heard you should close your browser when you're done with the secure website. If you log on in a PRIVATE window and close the private window afterword but leave the main FireFox window open, is that the same thing? I think it is and the private window will delete any login or activity info as if you closed the browser, I just want to confirm with someone more knowledgeable before I make a bad assumption. It also seems to have the added benefit of deleting anything you might download and save elsewhere from the download folder so you don't have to delete it from the DL folder and then the recycle bin. Seems like it's good practice to use the private window this way. Again, just looking for a 2nd opinion.

Thanks,
