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.

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

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!!

• OS: Windows 11 25H2 (26200.8037)
• Browser: Firefox 148.0.2
• Camera: Logitech C925e

When I go to a meeting on meet.google.com, Google Meet says "Camera is starting". My camera light flashes and then stays on. However, Google Meet is unable to connect to the camera.

Upon closing the tab, the camera light stays on and the camera is unresponsive to all apps. The camera must be unplugged and plugged back in to work again.

The issue does not exist when I go to webcammictest.com in Firefox or in other desktop apps. The camera works correctly on meet.google.com when I use Chrome.

I have tried removing camera and microphone permissions to meet.google.com and re-granting them. I have tried deleting all meet.google.com cookies and storage.

Gmail will suddenly not open in Firefox with error saying there's a problem with my cookie settings--i did not change settings and cannot find any way to fix this. See attached image. I follow link in error message for "browser specific instructions" to fix it but there are no instructions.

Gmail opens in Edge and Chrome. I've spent some real time on this, cleared system memory, checked cookie settings wherever i can find them. Searched for tips online. Did Google do this on it's own to force me to use their browser? Wouldn't surprise me.

To eliminate multiple problems (including disappearance of bookmarks) in desperation I uninstalled and cleared out all remnants of FF, then installed a new FF. Fortunately I had recently imported all the stuff FF more recently lost into MS Edge so I used the FF feature to import from MS Edge. However, every effort to import my bookmarks failed. So I used MS Edge's ability to create a HTML file of my bookmarks and then in FF used the "import a HTML file" feature to get them into FF. However, FF fails to recognize my bookmarks as bookmarks. It lists them in a "Favorites Bar" which cannot be strewn horizontally across the top of my screen as did my bookmarks in the past nor be viewed as bookmarks.

So HOW can I get FF to change the "Favorites" into Bookmarks?

In the tiny image I've uploaded, IF it can be read, the Bookmarks selections are "empty"

Today, when I opened my firefox page, I was forced to create a profile whether I wanted one or not. I did so, and lost all my established bookmarks and other links to items I frequently use. How can I recover those?

A few weeks ago, I started to get repeated messages from Firefox asking me to make Firefox my default browser. Firefox has been my default browser for years, and I have never made anything else my default browser. Anyway, I followed the prompts and re-selected Firefox as my default browser. A little while would go by (sometimes as little as a minute) and I would again get the prompts to select Firefox as my default browser. This append 20 or 30 times. And, every time it happened, all of my saved passwords disappeared, but would reappear when I re-selected Firefox. In the last week, this situation has gotten a lot worse. Now, the saved passwords don't come back. And, the prompt you usually get when entering passwords to a new site offering to save the password doesn't appear any more. So, the only way I can rebuild my saved passwords is to enter them manually, which I am not going to do because it would take a couple of hours and then I'm pretty sure they would all disappear again. Also, I like to go to my homepage when I open a new tab. Can't do that anymore. When I open a new tab, I get a new private browsing window. I have checked all my settings a dozen times, and they are correct. I have combed your support sites and there is nothing there to help me. I don't want to dump Firefox, but I cannot continue with it behaving as it does now. Is there anyone anywhere in your organization who can help me? Thank you.

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).

Thank you for the help! I'm wondering if other AI chatbots, Lumo, in particular, will continue to be added as options to the updated sidebar? An unofficial extension exists (https://codeberg.org/daskashk/lumo_ai_by_proton_chat_in_sidebar) that adds the ability for a link to appear in the sidebar. However, it does not offer the full integration that the official browser update provides to the other supported LLMs. I like Lumo for its privacy, encryption, and the ability to make "Projects." Thanks again for the help.
