Beside my VPN icon in toolbar is a circle with a exclamation mark inside. When I try to turn on VPN, I get a message that says that I cannot and to try again later. Why?

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.

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.

When opening the "Show all history" window (command Y) the text is garbled. I have checked the font book and there are no duplicated and I have validated all fonts. I have tried using the troubleshoot mode and occasionally the text is rendered correctly but mostly it has no effect. There is no other location in the browser where the text is garbled. I have tried changing the text in the advanced settings and both performance settings are disabled.

Good Morning,

my Firefox /Mac OS blocks my NAS in my local network. otherwise I can contact my NAS via Firefox / Ipad OS. Where´s the problem, Firefox kann sich nicht mit dem Server auf 192.168.178.112 verbinden

I don´t find any switches to change.

I can"t access my individual bookmarks. One day ago, Sunday, April 5, 20226m I was able to access my list of "other bookmarks" and click on whatever I wantded. Today, April 6, 2026 I cant do that

Up until the last week, on my iMac, if I clicked on the Firefox button on my bottom toolbar, both of my main FF windows (each with multiple tabs and open all the time) would come to the front of the screen.

Now, only one window comes up and I have to specifically select the other window to see it.

Is this a new behaviour or have I inadvertently deactivated whatever it was that let me do as I have always done previously!

I can't find any setting that appears to refer to this condition.

All of my passwords were deleted from Firefox on my MacBook. I am trying to get everything to sync because the passwords are there on my desktop and they are there on my phone. However when I try to sync from my phone nothing happens. When I try to sync from the macbook it is telling me to go to Firefox on my phone and sign in on my phone. The problem is that I'm already signed in on my phone so it is really difficult to follow the instructions because what it's asking me for I'm not able to do. I'm just trying to figure out how to sync the passwords and get the passwords back in the Firefox on my MacBook.

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

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.

This is the message I get when trying to login to my Costco account: Application error: a client-side exception has occurred (see the browser console for more information).
