Extension has permission "Access your data for sites in the abc.de domain".

The documentation says that such extension can read "data you enter into those web pages, such as usernames and passwords"

Can extension send such data away (for example to its developer)? What kind of permission is needed for that? Can you quote exact name of such permission/s from linked article so i can lookup that?

I am currently experiencing a technical issue with the Firefox browser that is impacting our workflow. After accessing a specific URL, we encounter a problematic page that we're unable to bypass. This is reminiscent of a past issue that was resolved by modifying certain configurations in Firefox's about:config page. Unfortunately, the previous fix is not effective this time. I have attached the error page with this ticket.

The settings we've adjusted are as follows: - security.insecure_field_warning.contextual.enabled = false - security.certerrors.permanentOverride = false - network.stricttransportsecurity.preloadlist = false - security.enterprise_roots.enabled = true

Can anyone tell how I can bypass this page?

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

Hi, I have a lot (+1600) password stored in my profile and i would like to clean its and delete olds ones. So i look for an utility or an extension to mark only those i want to delete (or keep).

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?

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.

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.

M2 MacBook Air running macOS Ventura. When I open a website which wants access to my camera I am asked if I want to allow this. I say "Allow", and the light next to the builtin webcam turns green, but I see nothing in the camera sub-window on the webpage which was granted access. No error message, just no camera video is shown by the webpage. In the menu bar is a camera icon which I can click on and confirms I have "Allowed" camera access. Setting / Privacy / Permissions / Autoplay is set to Block Audio. I have verified the camera works with other apps (Photo Booth). How can I diagnose this?
