When using the built-in Firefox AI sidebar and clicking the "Summarize page" button, I consistently get the error: "431 Request Header Fields Too Large" from chatgpt.com.

Cookies were cleared multiple times Extensions (including AdGuard) were disabled The issue persists

Previously, changing a privacy setting temporarily helped: switching from "block all cross-site cookies" to "block cross-site tracking cookies and isolate other cross-site cookies". After that, the feature started working.

However, after restarting the browser today, the issue returned, and changing this setting no longer helps.

I would also like to note that currently there is no way to disable or hide the "Summarize page" button, even though I did not need it initially. I tried to configure things so it would work properly, but was unable to do so.

Steps to reproduce:

Open any webpage Open the Firefox AI sidebar Click "Summarize page" Observe error 431

Expected behavior: Page summary should be generated successfully.

Actual behavior: The request fails with HTTP 431 error.

AV1 Hardware Acceleration stopped working. In about:support->Media->Codec Support Information Firefox states that Harware Decode AV1 is supported but it uses only Software Decoding. AV1 worked perfeclty before in Firefox, is still working in other browsers and apps in my system.

Hey there Mozilla team, Love the new free built-in VPN for the browser and Kit. :D But I have problems with enabling the VPN. I am on Linux Kubuntu and the VPN cannot start. Funnily enough when i turn on Mozilla VPN on device level the Browser VPN does manage the enable itself.

Also I have a question about the Mozilla VPN browser extension. Is support for Linux still being worked on? And could we see the support being implemented soon?

Have a wonderful Day

Hi, the home page shortcuts used to be bookmarked sites I selected, and they stayed in one place. After a recent update Firefox litters the page with recent searches, displacing the ones I saved. I can't see a setting to select recent search shortcuts ON/OFF, how to restore the old (and very useful) shortcuts?

Every time I open Firefox I get a message saying "Getting close to your VPN Limit. You have _ GB left. Your data will reset at the start of next month" and I want to stop seeing it

First of all I've noticed that even logging in to the account management page doesn't work with my vpn on. So of course sync itself doesn't either. It works perfectly fine with it off though. Is there an IP address that I can add to split tunneling to allow only the sync/FF account manager through my vpn? Or another way I'm not aware of? I'd rather not have to allow the whole browser through my vpn if possible.

I've recently had a bit of a strange problem. I use on-line banking. When I wanted to print off the latest transactions, I proceeded as usual. Then, when I clicked 'print', the list of transactions was overwritten by an (apparent) HSBC document headed 'Reactivate your unclaimed account'. I could still print my transactions, but only at a much larger font size.

I phoned HSBC and could not get any help. It was suggested I took the printed pages into a local branch (fine suggestion with all the branches that have closed!). I did. I also took my pinpad into the bank so I could sign in on their computer. Surprise, surprise, the strange document didn't appear. The bank said that it must be my browser at fault and suggested I update the version. However, they were able to confirm that all my accounts were fault and trouble-free, with no suspicious activity.

This evening, I tried to do just that. Nowhere could I find any way of updating Firefox, so I deleted the entire app and reloaded it, using Edge. Once set up, I tried again. I still get the document. If I try using Edge, I don't get the document. Now I'm completely puzzled. What makes me even more suspicious is that this strange document shows all of my HSBC accounts, with the correct figures, but at the foot of the first page, in large letters, is the line "Are you sure you want to redirection?". Very odd language. At the head of the second page is another line "You will be token to a new page to login an view your credit card details". More odd language.

This problem has only occurred on Windows 11 - it never occurred when I was using Windows 10. My anti-virus software (Bitdefender) reports my system is clean. The problem also does not occur when using any other web browser.

My conclusion is that there is a problem between Firefox, Windows 11 and the HSBC online app.

Please can this be investigated. Many thanks, John Jesson

I'm having problems with AOL ad blockers. The program says that I have ad blocker plus turned on in my Firefox extensions. I turned everything off in the exension menu and still have the same issue.

Firefox update did not fully complete. All bookmarks have been lost. I did not have a back up file. Can I still get them back? It's still asking to finish setup and has not completed.

What happened, All my important bookmarks are missing. I have had to log into every account I have, No saved passwords. Really upset. I need help to restore all this information that I need

vary unhappy with the new update. never have had issues with fire fox like this. when going to zillow.com i get this message: upstream connect error or disconnect/reset before headers. reset reason: connection termination. I noticed this is only the fire fox browser having this issue. i have already disabled ad blocker and vpn reset fire fox lost all my tabs! reset the computer and nothing still, i get the same message. i have used fire fox since it was a thing and recommending it always. getting a different browser right now to do my house buying, i don't feel safe using fire fox for this adventure any longer. my apologies if this seems like an emotional decision but i see this in everything that gets to big they lose the plot its an infection that is embedded in everything now, windows, home and car pricing. major changes to os and how its used. company's hate there customers anymore and were noticing.

I don't know which topic describes my question. I want to put the New York Times as a short cut on my firefox home page and it won't do it. For a bit of history, I USED to have the short cut and one day it was removed by Firefox when it re-arranged things.
