Firefox Support Forum

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...

I have moved to another password manager, and would like to completely remove my saved logins from my Firefox account and stop using the auto-fill, auto-suggest feature. However, no matter how many times I delete my passwords and Sync, they keep appearing in my Android Firefox app. I have cleared the app Storage and Cache, I have reinstalled it from scratch, but no matter what I do they reappear. My (also Synced) PC on which I deleted the passwords has not shown it again since I deleted them there.

I just want to completely delete all my logins in my Firefox account, permanently and across all my devices. How can I do this?

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....

Some sort of problem deleted saved passwords on my desktop passwords on devices are saved I can tried to sync them but nothing happends. Whenever the request to save a password it is not saved on desktop.

Update 123.0 deleted all my firefox data from logins.json. backup files are corrupted or have no data. No support article suggestions have worked. The .json files indicate that there is data, but appears blank in notepad, and wont load in json reader in firefox

I do not use SVG

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?

Hi,

I'm developing web app. I created and set up ssl auth for localhost with self signed cert.

When I hit my endpoint with firefox I see:

Secure Connection Failed

An error occurred during a connection to localhost:8081. SSL peer cannot verify your certificate.

Error code: SSL_ERROR_BAD_CERT_ALERT

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

How to disable security in FF so I can test my endpoint?

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?

Hi,

I've been using Firefox on my laptop and my phones for years. I have a concern about my saved passwords in Firefox. If I need to lookup a password, I go settings, saved logins, put in my pin# and search and copy my password. Many times; however, when I get to the enter password on a website, Firefox comes up above my keypad and will let me just hit the down button to pick my credentials and automatically fills in my credentials without asking for my pin! It will also come up above keyboard to unlock Firefox? Please help me to clear this mess up. I want to have to put in a pin for my passwords. Anyone could get into my websites if my phone were taken, etc. I know I un-installed the app for passwords from Firefox when it was no longer available, sorry can't remember name of this app. I hope there is an easy way to make this happen. The only way I want to look for a password is with a pin #. It's a pain but I am OK with this.
