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.

All but 2 of my previous saved windows have been lost. They are not recoverable or present when trying to use "Recently closed windows." How could this happen? More importantly, how can I recover them? They contain numerous tabs that will be impossible to recreate from memory.

I have always been able to watch "NPR Watch" video clips. It was not functional on my new iMac with a new install of Firefox 149. I checked my laptop and it was fine on v147, but when updated to 149 it too was not functional. Please provide a step by step fix. I tried fixes available on internet without luck

If I have two or more tabs open it happens very often that all tabs which are not in use are closed independently by the browser. At the same time Firefox independently creates bookmarks from some closed tabs in the bookmark toolbar. I always use the latest version of the brwoser and no extensions. I would be grateful for a solution. Thanks!

Since changing profiles, which I regret immensely has created a problem when I want to completely clear all history despite choosing the correct settings under privacy and settings. The only box checked the does not clear is the temporary cache files and pages. Even in the menu bar under history and I choose history and clear all history it does not function. I have to manually uncheck the box and check it again and enter clear. This is frustrating, because this has never happened before. FYI, I do not use the AI feature.

QUESTION FOR FACEBOOK AND MAX FIREFOX USERS OS 26.3.1 on MacBook Air. Just called Apple trying to figure out if there is a setting somewhere to allow drag and drop of Photos into Facebook. I can drag and drop Photos into new FB posts, FB Messages, texts, emails etc. But I can't change the Cover or Profile Photo on Facebook by drag and drop. Facebook doesnt seem to have access to any photos but those previously posted. After an hour+ with Apple, checking all the settings o FB, Apple, and Firefox, he thinks it's an issue with Firefox and Facebook. I don't have a similar issue on IOS..IPhone or Ipad. Any thoughts?

I have noai.duckduckgo.com set as my default search engine. Almost always (but not quite every time) when I type anything into the address/search bar, I get a page with a "Server Not Found" error. (See attached image.) Refreshing the page immediately brings up the results without issue, but I consistently get the error first.

Oddly, if I go into settings and switch to a different search engine and then switch back to duckduckgo, the issue will briefly resolve and it'll work fine for a short while... and then I start getting the error again.

Is there any way to fix this?

I have checked my setttings to ensure everything to do with history is checked and all is showing as it should but when I start typing in the URL search bar, none of my previously visited websites appear. They are still in my history so i know they haven't been cleared but it is frustrating, as even after I manually type in the address, if I try to go back to that website later the same day it still doesn't appear.

Hey,

after looking through many Forums and solutions on the internet, nothing can resolve my issue, so i hope this one can help. I just switched to Firefox and have the reaccuring problem, that i cannot load sites, that are located in my local network (e.g. homeassistant.local; 192.168.8.265:2283).

I always get a "server not found" error from firefox and the certificate information, that i am communicating through an unsecured connection (haha, yes good joke firefox. I know my local services do not all have an SSL certificate.) I already tried altering settings for Proxy, DNS over https, MACos Safety settings but nothing helps. I am jsut looking for that one "trust this domain" button, that i get on 'ALL OTHER BROWSERS like Chrome, Safari and Edge...

P.S.: All the services are up and running and i can reach them through any other Browser.

i have a mozilla account i tried to login with my username and password but its asking a code sent in email unfortunately i dont have access to email i thought creating account in mozilla is enough as all my passwords are synced there and password of the email is also synced in this mozilla account need to login for getting the passwords

Running on a Macbook with Tahoe OS. Certain websites will not display my responses to a checkmark box. Certain websites will not permit changing a checkbox default setting. Specific example: https://cards.barclaycardus.com/ has a checkbox with remember user name defaulted to a check. Attempts to click to remove the check do not work. Also, on certain websites when entering login information that is incorrect, the message indicating to correct the item(s) in red or highlighted does not display the incorrect items in a highlighted condition. In fact at the bottom of this page, the response box labeled Email me when someone answers the thread does not display a response when I click on it, even though the "response" is accepted.

I followed the instructions to set a security and there is no option to do it. I need to be able to login to all of my gmail accounts. The correct password was used, and is shown when I click the key icon and is accepted on other browsers. What is the problem and how do I fix it?

Since latest update when trying to view pages with artwork on them I get a message that the page is slowing down Firefox and asks me if I want to stop the page to speed up the browser. I do not want to stop the page so I click the X, but Firefox refuses to load the pages at all anyway! I can no longer view many sites due to this issue. Please get rid of this awful code! Thanks.
