We have an intranet site behind an Active Directory Federation Services (AD FS) - after updating the SSL certificate, the website will no longer allow Firefox clients to log in.

They will be prompted to sign in (with a default sign in prompt, not even the website login prompt), even if you enter the correct user/password it will continue to prompt you. The new cert works with Edge, Safari, and Chrome - I've enabled the following settings in about:Config network.automatic-ntlm-auth.trusted-uris, network.negotiate-auth.delegation-uris, network.negotiate-auth.trusted-uris, and set signon.autologin.proxy to be true - but the issue still persists.

Has anyone seen this/been able to figure this out? I've seen a few other posts, but no resolutions. Does Firefox not support Certificate Signature Algorithm SHA-384 With RSA Encryption? This is the only difference I can see between the 2 certificates; the original is SHA-256 With RSA Encryption.

Thank you!

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?


Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

I've been trying to reply to moderator "Phil" who requested information regarding Firefox crashing while on Youtube. When I press "Post reply" all I get is an error message:


An Error Occurred

Oh, no! It looks like an unexpected error occurred. We've already notified the site administrators. Please try again now, or in a few minutes.

It's important "Phil" gets my message as others may be affected my possible Youtube shenanigans. If possible, can you forward this message to "Phil": Unfortunately there are only two reports generated during the problems with Youtube:

bp-91f496a8-971c-4a87-a642-011d10240220 bp-7d820f6c-dcf9-4cef-bb60-1a9f50240217

The problem caused my system to stop responding forcing me to power cycle to clear my PC, so no reports could be generated. Hopefully these two will show what the problem is. In the meantime, can you check the reply system to make certain it's working properly?

Hi Windows 11. Every time I open a new tab and make a search I get a field under the bookmarks for my google account. I do not want this. On the web it says I should go to account settings and scroll down to the Linked Accounts section. I cannot find that section. Elsewhere I read that I have to do something in my google account as well. How do I get rid of the field for my google account when searching in firefox, please?

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

A tab for the Etsy website automatically appears every time FF starts up. How to stop this?

Just began after using the site a couple of times, but I did not indicate or click a setting on the Etsy site to ask for this.

All solution suggestions seem to be for pop-up ads, and don't work to block a website. Is there a way to block this?

Hello, I am writing this as I have yet to find any answers

My problem lies in the fact that while browsing on YouTube the ratio suddenly changed with no warning. When in a private window it does not change the ratio and I have no idea as to why. I have tried to restart both FireFox and my computer, but none of this have helped, I then tried disabling all my extensions, this also did not help, and as I have yet to find anything about this problem elsewhere I hope that I could get my answer as to why this has happened, and how to fix it

The first picture is the ratio that is the "normal" and the second is should be, does anyone have any answers?

My company uses Oracle Fusion as its ERP solution, and I frequently have to download files from Oracle BI Publisher. Prior to V123 of Firefox, which installed this morning, I could click on the file/report in Oracle Fusion, and the file/report would get moved to my Downloads folder. After the update to V123, nothing happens after I click on the file. I had a co-worker replicate the problem after his Firefox updated to V123. Please advise if this is a known issue and if there is a resolution.

This AM, I opened my Firefox Browser for the first time today and attempted to sign into my EaseUS account. I was confronted by a "request" to add "Browsing Safety by Safely" as an add-on to my Firefox. However, it would not let me to skip this "request" without adding it to Firefox. Nothing I attempted worked. I've never heard of a compulsory add-on, least of all from Mozilla! If I would have had the time, I'd have tried different accounts/log-ons/browsers, etc. However, I didn't have the time to do it then. Help please.

What is this? Have you heard of it? Do I have a problem? Should I remove the Add-On?

Thank you.
