Firefox Support Forum

I am trying to access the online library website for my college. I had no trouble all week then all of a sudden I keep getting this message: "Unauthorized LTI Launch Request 401

   Please check the configuration settings used for the LTI/OAuth/OpenID access.
   Your browser's "Block 3rd party cookies" or "Prevent cross-site tracking" setting can also cause this error."

I already changed the cookies settings to allow this website and my school's website. I don't understand the issue and why it popped up out of nowhere. I use firefox latest update on Windows 11. I do use a vpn but I used it the whole time, even when the site was working and I have tried turning it off. It doesn't help.

I have a local web server which is misconfigured. Its my server, its on my LAN, and no data traverses any devices not under my control. I need to be able to access it via HTTPS with an expired certificate in order to FIX THE EXPIRE CERTIFICATE. How do I do it? Firefox used to have a "accept the risk and continue". Whoever took this feature aware has created a very significant problem for me and I want the capability back.

Hello, In order to log into Netflix I have to uncheck the Cookies box and Private Browsing box in Privacy and Security under Settings (I usually run with these enabled when just browsing). When I do this it asks for a Restart. Upon Restart the Netflix Login page always appears on its own. I am curious as to how Firefox is getting steered to the Netflix Login page when it is not being specifically told to go there. I assume it is somehow tied to the unchecked boxes. It's not a big deal to me but I am curious about what is going on in the background and the dynamics involved. If someone has the time to explain what is happening I would appreciate it. Thanks you !

And thanks to Mozilla in general for keeping Firefox so excellent.

How do I disable secure connections for local domains? like http://nas.local or http://nas.home.arpa ?

I search for the subject but nothing came up. Apologies if this has been asked before.

Hi.

I have several internal sites, each signed with their own internal CA/subCA. These CAs are all named the same, but have different crypto materials.

If I import just 1 CA into FF (directly or in Windows store with security.enterprise_roots.enabled ), the site with that CA works fine (browser warning is not presented), but ALL those other internal sites give this error:

An error occurred during a connection to 10.1.1.1. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE

with no option to add a security exception.

If I add the CA for another site, that one works as well, the others won't. If I remove all the internal CAs, all the sites start working again (with browser warning, ofc.).

I tried in Chrome and Edge and I get the option to create a security exception for the sites for which I did not install their CA, which looks like the ideal/preferrable option to me.

Is this as intended (and why?) or can it be fixed?

This looks somewhat similar to this: https://support.mozilla.org/questions/1170738

Thank you. Davide.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something fascists do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

Hello, I need a bit of help. Specs: FireFox 127.0.2, Apple Silicon M2, Sonoma. For some reason in my privacy & security settings with enhanced tracking protection, it's set on Standard which I believe is the default but after some time passes it switches itself to Strict, or Custom settings, then none of my pages load properly or not at all. Can someone tell me how I can get it to stay on the Standard?

Thanks

I use Firefox with a VPN. I also use the Chameleon extension to alter my fingerprint. When I log into Messenger.com it asks if this is me and gives my actual, physical location. I've checked in settings under location and it doesn't show any sites requesting my location. I have it open in one of the tabs where it's showing my location. I have block all location requests checked. How can I get Firefox to not show my physical location?

Also on this page, it gives I'm using Firefox and the OS I'm using. Both are supposed to be changed for fingerprinting protection.

This looks like it could be a big security loophole. Any help is appreciated.

How can I use Firefox for private browsing or anything when you cannot even keep me as your Default Browser? Edge changes it everytime!! They override you so they have taken over my computer so I can't have firefox as default browser or anything? Thank you, Margaret P Miller peggiemiller1209@gmail.com
