Now the latest update solves the problem of autoplay on YouTube can something be done about viewing the whole site? Videos take forever to load or generally never load and when they do all it shows on the page is the video and nothing else.

I go to my YT history and the page will not load. YT at times says I am offline when in fact I am not because I am also at the same time,while waiting for YT to load, viewing articles and videos on Yahoo and MSN as well as other sites.

This has only started today, March 12th.

Hello everyone,

We are currently investigating an issue where browsers are sending HTTP requests with Connection: close in the header during integrated Windows authentication (NTLM authentication) via SAML Service Provider (SP), leading to premature termination of the TCP connection.

This behavior occurs in the middle of the authentication process, preventing the NTLM authentication from completing and subsequently prompting for re-authentication.

We have observed the following browser behaviors:

Chrome and Edge: These browsers function without issues, communicating with Connection: keep-alive. Safari (macOS): Older versions of macOS with Safari exhibit the Connection: close behavior, leading to authentication failure. Newer versions of macOS with Safari work correctly with Connection: keep-alive. Firefox (macOS): Even on the latest versions of macOS, Firefox continues to attach Connection: close, resulting in authentication failure. Upon reviewing logs, we've identified that various browsers attach the Connection: close header during the NTLMSSP_NEGOTIATE request in the NTLM authentication sequence. Although this happens in an environment with a load balancer, we have confirmed that the load balancer is not modifying the header; rather, the client (browser) is adding it.

We would appreciate your insights into the conditions under which Firefox attaches Connection: close to HTTP requests, especially considering the differences across macOS versions and other browsers, addressing the following points:

Are there any known conditions or past cases where Firefox outputs Connection: close in an NTLM authentication environment via SAML SP? Given that older Safari versions show similar behavior, we are also considering if there's a common factor depending on NTLM authentication and browser version. What are the general heuristics, logic, or triggers for a browser to decide to "close" a connection or to attach Connection: close? We are particularly interested in cases that occur mid-authentication process. Could specific configurations (e.g., the combination of SAML and NTLM authentication, or the presence of an intermediate proxy/load balancer) potentially influence Firefox's Connection: close behavior? Are there any additional logs or debugging information we should collect from the Firefox client side to further pinpoint this issue? Any guidance or suggestions you could provide to help us resolve this problem would be greatly appreciated.

Thank you.

Listen I have a profile in another partition in Mint and want to transfer my Bookmarks/profile etc to my new 22.3 install but far too complicated. I also have a previous Key which I no longer wish to use as it has deleted all 20 years worth of messages.

I don't plan to use any provided AI chatbot. I want to use models that I have downloaded and tested myself and which run on my PC. So please add the possibility to connect through major LLM APIs, the same way other tools way simpler than Firefox already allow to do.

i can't use the microphone in the AI chatbox. i have been to several sett tings in different places and none have the option to allow it'. I clicked on every gear icon and setting link (and AI chat link) i could find in the firefox browser

Hi everyone,

I’m running into a frustrating issue where Firefox is opening PDFs in two places at once.

The Problem: When I click a PDF link, Firefox opens the file in a new tab (internal viewer) but also launches the standalone Adobe Acrobat app to display the same file. I only want it to open in Firefox.

Details: - Settings: My "Applications" setting for PDF is currently set to "Always Ask." - The Glitch: Even when I manually select "Open in Firefox" from the prompt, Adobe Acrobat launches anyway. - Timeline: This started happening 2 days ago without any manual setting changes (I think it might be after a firefox update? I might be mistaken)

- Troubleshooting done: I have tried toggling the action to "Open in Firefox" directly, but the dual-launch behavior persists.

Thanks

Hi Everyone,

I’m Harmandeep Singh Kandhari from India, A Health and Wellness Motivator and Now, Recently, my Mozilla Firefox browser has started using much more memory than usual, and multiple tabs cause noticeable slowdowns. I haven’t installed many new extensions. What steps can I take to identify the cause and optimize Firefox performance without resetting my entire browser profile? 🦊💻

Thanks, Harmandeep Singh Kandhari

Tab groups work well with the standard tab bar, but when changing to vertical tabs, there is no clear way to expand the menu (aka hit the 'V' at the right of the tab bar for horizontal tabs) to see the tab group.

The only fix i found was to turn off vertical tabs, open the tab group, then turn on vertical tabs again.

I love my current Firefox settings, bookmarks, folders and color, background image, dark mode. All I want to do is to create a Firefox browser backup file. I don't want to restore or sync anything. I just want a backup file in case of computer failure to restore to my next computer if ever necessary. I'm using Windows 10. I think they used to be "json" files? The only "Backup" link in the menu only addresses Restoring from a file. I just want to create a backup file for this current browser just the way it is. Is there a simple solution? Thank you SO much!!

When I go to the all trails site, I get a blank page, with only the words, "Please enable JS and disable any ad blocker" I checked my settings, and my ad blocker in Firefox is disabled. I cannot figure out, in my settings, how to verify that my javascript is enabled.

If synchronisation works bidirectional - does that mean that all bookmarks vanish on all added computers when they are erased from one of them? Can and should one define one of the computers as the one from which the installations should be preserved?
