Hello Mozilla, When using Firefox I always have Enhanced Tracking Protection turned on - Custom, all four categories are checked, no exceptions are identified. Yet when I look at the Process Manager I consistently find third-parties (defined by me as NOT my OS, my browser, or any website I have visited during this session). As I write this I have just killed the following 4 processes, which I think Firefox should have caught. And in a few minutes when my active window is another application or when I take some browser tab to full-screen mode, these processes I thought I killed will reactivate. The current sample:

kampyle.com setpay.com signifyd.com trustarc.com

You may identify these as innocuous, but they are the very definition of third-party sites. Anything that calls itself TRUST is the first thing I'm going to question. Its exhausting having to police this constantly. What good is ETP if I have to supplement with my own time and energy, diverting me from my primary tasks?

Steps taken: Before submitting this I took a moment to check all the sites I have open or have had open on this device in this browser session. Clicking on the shield near the web address field, I have confirmed EPT is ON for each of them and I can see that many trackers, etc., are apparently being blocked. I also re-checked the related Firefox settings to ensure it remains as I selected.

Info: I work in remote locations, and carry my own hotspot with me. Its a cellular hotspot and I can have many devices as well as many tasks on any single device sharing the bandwidth. I started looking into this because these extra processes interfere with my use of my own devices and the bandwidth that I need and PAY FOR.

Thank you for your help. -LLD

Greetings. I recently upgraded to Windows 11 and started using Firefox again. In order to be more secure and private I am reviewing all of my settings everywhere. I am concerned that the security certificates that are currently in my Firefox are safe, secure and current. I know the internet is worldwide and bad actors can from any country but when I see them from certain countries that does concern me. Is there a way to verify the certificates are good? Is there an harm in deleting certificates? Is there any suggestions of what countries, websites to stay away from concerning certificates? If the validity is expired should I delete it? I do not like to make assumptions. I try to make informed decisions. Thank you, bkh8611@gmail.com

Hello, i need help. If I create shortcut, and start firefox in another profile, like this:

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -class FF2 --profile "C:\Users\mire\Desktop\TEST\Apps\Instagram" --no-remote instagram.com

And if i set in "user.js" --> user_pref("taskbar.grouping.useprofile", true);.

For some reason after firefox starts, or after second start, firefox icon on the taskbar turns into a private browsing icon!

I tried everything to prevent this, I tried to add:

user_pref("browser.privateWindowSeparation.enabled", false); user_pref("browser.privacySegmentation.windowSeparation.enabled", false);

Nothing works...

I checked million times that im not in private browsing, and i'm not.

Then, after some tests I found that if I remove the flag: "user_pref("taskbar.grouping.useprofile", true);" from 'user.js' and 'prefs.js', and start profile again, taskbar icon becomes normal firefox icon.

Is this a bug?

And what should i do if i want to have separate grouping for the PROFILE2, and i don't want to have that private browsing icon?

You can see in the picture what was happening...

Hi,

I noticed that the shortlinks/websites on my startpage (the House icon) are placing cookies as soon as I start Firefox. Not all of them and also in a random manor. This does not happen in Private Navigation, which i almost never use.

For me this is rather strange, I do not visit these shortlinks and already being tracked by those cookies. How can this be changed?

My settings are to clear all cookies and history at closure. Subquestion: Do I need to choose Options/Close or does this also work by clicking the X in the right upperhand corner to close Firefox.

Hope someone can shed some light... Lasco

This one really caught me by surprise! I have an internal Django database system. Staff typically use Firefox or Chrome to access it from Linux or Windows machines. As part of this system, it uses Grappelli library which in turn uses TinyMCE V3.5.8. Specifically, in a text box TinyMCE provides advanced editing and fonting. Allows the user to embed links or images. This system was working fine on Django 2.2. My provider (Python Anywhere) retired the server image I was running on, so I updated everything to Django 4.2 on their latest "haggis" system image. Everything seemed to transfer over without any errors - at first. In fact, it was a week later somebody tried to change a font colour by clicking the popup button that opens a colour picker. That pop up looks blank! (its not, the HTML is there but without the custom CSS nothing is visible)

In developer mode on Firefox or Chrome I can see what the problem is: The popup is disconnected from the parent. The parents CSS and classes - specifically tinyMCE - is not present. So its missing the styling and JS to operate. One of the first things the popup JS does is copy in the tinyMCE and tinymce classes from the parent. But they are not there, in fact .opener is null and .parent is stripped down.

What is really weird is on my test server, where I tested everything before updating the live server, it works! The test server uses Django's "runserver" to run a very simple (unsecure) http server just to test code. Whereas the live server is locked on HTTPS.

What confuses me is I don't see any console log messages that would indicate the browser decided to "protect" me. How can I figure out what is going on? Or disable this feature for a test?

I am writing this on my Dev machine using the browser I test with, so I shall try to paste in tech info below.

Just to reiterate, in this browser I can have my test server in one tab, my live server in another tab, test server popup works; live server popup does not.

Thanks in Advance, Richard

PC/WIN7 - I access my bank and get a login screen from them... when I enter my name and password I get a "FILE NOT FOUND" ... but it accesses just fine on my android phone or on my other laptop running WIN10... maybe a problem in firefox site permissions ?? Used to work up until about 4 mos ago....

I use OnlyKey usb key as FIDO2 MFA with most of my accounts. On Firefox 123.0 on MacOS Sonoma 14.2.1 (23C71) however, I get presented with multiple pop ups to touch my usb key but the key expects only one input/touch and it fails when I touch it the second time. This was not the workflow that I used to use before and it still works fine on MacOS ventura with Firefox + protonmail.

In some recent update firefox privacy and security settings changed from saved logins to saved passwords. I find this much less useful. Can i change back to saved logins?

Dear Support Team,

I tried enabling localfilelinks in firefox and found this thread https://support.mozilla.org/fr/questions/1264779 which mentions creating a "user.js" file and adding this:

/ Create policy enabling http: or https: pages to link to file: user_pref("capability.policy.policynames", "filelinks"); user_pref("capability.policy.filelinks.checkloaduri.enabled", "allAccess");

// Sites to which the policy applies (protocol://hostname protocol://hostname) user_pref("capability.policy.filelinks.sites", "http://example.com http://intranet");

then reloading firefox.

The fix worked and i was able to use local files in firefox. My Problem now is reverting localfileaccess to default (blocked).

i tried modifying the "user.js", deleting it, deleting and reinstalling firefox, cleaning the firefox install and creating a new profile. when i deleted user.js the enabled options vanished from "prefs.js" but local file access was still enabled. I also tried to edit the generated options in about:config but i cannot get it to revert to localfile access beeing locked and couldn't find any way to fix my problem.

Is there an easy way to relock this?

I'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

Randomly after certain updates, the browser history gets randomly erased. The cookies are not deleted, so my sign in information is retained across my usual website (no issue here).

I wanted to report this as it happened twice around the past two weeks and it was inconvenient.

I have Canon EOS Utility installed in order to use a better camera when streaming. For some reason, when I'm using Google Meets, it will only let me use EOS Utility, ignoring the option of using my laptop's webcam. I've tried revoking permission, but when it asks me for permission again it won't show me my laptop's camera, only EOS Uitlity. I've tried disabling EOS Utility under Windows settings, but it's still the only camera that appears.

Hello

I recently reinstalled firefox . After I logged into my firefox account it synced everything.

When I check my password manager it said my passwords for 2 sites were last "used" today. It's after midnight now so it would have been in the last 1 - 2 hours.

One of the websites had a 2nd factor authentication and nothing came to my phone. I am just wondering if this was a password manager glitch or something to worry about. The place I synced is my family computer and no one else would log onto those sites since they are work sites. And again it's midnight the other computer is off too.

Im using Playwright with JS and when Im running ny test on FireFox i get a PopUp message to select the screen i want to screencast, even when im choosing screen and pressing "Share" its happened in the next test and not recording my tests. its happened only in FF. How im removed this PopUP ?Thanks. Using also Linux Ubuntu.
