Firefox Community Forum

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

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.

Is the following true and do you advise taking the steps mentioned. Cookies are dying. Google has been phasing out third-party cookies in Chrome, and Apple has aggressively blocked them in Safari for years. Advertisers needed a replacement that users cannot easily clear, block, or reset. Browser fingerprinting is that replacement: it is invisible, persistent, and rebuilds itself if your setup changes slightly. The result? Targeted ads that follow you across devices and sessions, even when you think you’ve gone "private." And because it operates below the surface of most privacy laws, the protections many people rely on simply don’t apply. What Actually Works to Protect Yourself Most people get privacy wrong by making their setup more unique (rare browsers + 30 extensions = the most identifiable fingerprint on the internet). True anonymity comes from uniformity, not obscurity. Here are the proven defenses, ranked by effectiveness: 1. Choose the right browser (the single biggest decision) Tor Browser – The gold standard. It forces every user to share the exact same fingerprint. Anonymity through uniformity. Brave – Excellent middle ground for everyday use. It randomizes canvas, WebGL, audio, and other fingerprintable surfaces every session. Firefox (with strict settings) – Strong out of the box and highly customizable. Avoid Chrome for privacy-sensitive activity; it offers no native fingerprint resistance. 2. Add the right extensions (Firefox or Brave only) uBlock Origin – Blocks fingerprinting scripts before they can run. (Note: Chrome’s Manifest V3 severely limited the full version; Firefox is required for maximum protection.) CanvasBlocker – Randomizes your canvas output whenever a site tries to read it. 3. Flip one powerful Firefox setting Type about:config in the address bar → search for privacy.resistFingerprinting → set it to true. This standardizes canvas, timezone, fonts, and other outputs so you blend in with everyone else. Takes 30 seconds and makes a measurable difference.

How do I stop pup ups with several different warnings. At the top of ALL popups say Mozilla Firefox . I clicked DISMISS, then another one will pop up. 1.) Red shield with the word Warning! Click here to secure device! anti virus notification. 2.) Red and black shield say Virus found. 3.) Blue Windows symbol with a the yellow triangle and !, Click here to remove it 4.) red setting wheel, Trojan virus detected, Scan and delete your system.

Please help

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

I need help with annoying pop-ups. I followed instructing. It only say allow, not block, when I go to settings, security & privacy, checked block pop-ups and third party redirects.

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

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:

Device Bound Session Credentials

Google has made Device Bound Session Credentials (DBSC) generally available to all Windows users of its Chrome web browser.

What is FIREFOX doing to defend us from session cookie stealing malware (STORM)?

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

I recently switched operating systems from W11 to Linux (Zorin), and installed a new copy of Firefox. I rely on local web pages I have written for some of my work, but the new copy of Firefox does not find the file. For example, when accessing an image, e.g., file:///magrathea/dmpase/home/index/coastal24.png, Firefox gives the message:

File not found Firefox can’t connect to the server at local file What can you do about it? Check to make sure you’ve typed the website address correctly.

The address is correct, that is, the file resides at: /magrathea/dmpase/home/index/coastal24.png and the user does have permissions to read the file. I've tried adding up to five '/' characters to the beginning, and I have turned off all of my installed add-ons, but without success.

An apparently related problem is that double clicking on a '.htm' file also changes the address, for example, from '/home/dmpase/Desktop/index.htm' to 'file:///run/user/1000/doc/f07a8988/index.htm'

And finally, the "Brave" browser is able to read the files with no errors.

How do I fix this for Firefox?

A while ago when using the setting firefox noticed that i was using a vpn and turned the settings off. At least that was what i believed. Turns out, that only works with browser vpn addons that use the firefox settings. But these addons do not use wireguard, but tls to encrypt your data. If i use a vpn, and want to use the dns settings provided by them, i have to turn of the feature the dns over https feature from firefox. I only want to use that feature, if im not "protected" by a vpn solution of my choice.
