Hello,

I see with windows Firefox version 118 a TLS extension id 65037 on every client hello handshake containing a bunch of data. Does somebody know what this extension is used for? I couldn't find anything about this on the web or in the firefox docs / release notes. Other browser (chrome / edge) don't have this extension in use.

Thanks

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

Hello:

I must use the magnifier that came with Windows or I cannot read the screen. All was fine until Firefox updated. Now, when I try to use the magnifier, Firefox and all the sites I am using freeze. The entire screen fades out, and an hour glass shows up. But nothing happens after that. I have to go to the task manager and close Firefox, then start it up again.

I checked for Windows updates and everything is current. I am using Windows 10.

How can I fix this?

Is there a main location where Firefox extensions (like Forecastfox) keep their settings? If so, or if you happen to know where Forecastfox in particular keeps its settings, I could use some help locating this folder. I have a settings file I could put in there to overcome some difficulties that the folks at Mozillazine can't seem to help with. (https://forums.mozillazine.org/viewtopic.php?f=48&t=2913287&p=14963740#p14963740). The folder I have is named Forecastfox.2023.04.22.21.11.51.txt

I want to report that spyware named FindItPro which I, foolishly, downloaded. Well, it's a virus, right? But no antivirus can delete it completely. It comes back and you can't find the source. So, there should be some problem in your browser that allows it to live.

I'll send you a website where I got it. [link to suspected malware removed] BE CAREFUL. Virus will be downloaded along with Opera browser or something. I'll send this report also to some antivirus company. Yes, I was foolish, but I hope you will fix it.

Hi! please help me lmao i'm not sure wtf is going on. I recently (as of a week ago) had to wipe my pc and reinstall windows 10 after a botched update. So i installed firefox on a practically new pc. thing is... when i turn it on, i get this baby in my taskbar (see image): right under the pinned firefox and thunderbird logo, i get a really scrungly OLD (and i mean OLD) firefox logo. clicking it opens nothing. hovering over it shows a preview of a blank window with a random string as title. clicking it only opens a second blank window with nothing in it. eventually when windows finishes starting up, it closes itself. i'm scared it might be a virus. help? how do i make it stop??

I'm running firefox 117.0.1 on windows 10 home single language 1903 (sorry if that's wrong, i dont know where to check otherwise)

What is the proper format for the ExtensionSettings policy registry key/value that is used to manage browser extension settings?

When looking at the ExtensionSettings page for Firefox or Chrome they both use an example that shows the registry key Software\Policies\Mozilla\Firefox\ExtensionSettings (REG_MULTI_SZ) being set to a long JSON string with every extension ID and the settings for that particular ID. For example...

{

 "*": {
   "blocked_install_message": "Custom error message.",
   "install_sources": ["https://yourwebsite.com/*"],
   "installation_mode": "blocked",
   "allowed_types": ["extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"
 },
 "https-everywhere@eff.org": {
   "installation_mode": "allowed"
 }

}

The problem with this method is that if I am installing an extension, and I overwrite what already exists in Software\Policies\Mozilla\Firefox\ExtensionSettings then all of those other settings get removed. So even if I am a non-malicious actor and just make a mistake with my installer I can easily delete every other extension's settings. Instead what I have to do is during install I have to read the current value of Software\Policies\Mozilla\Firefox\ExtensionSettings and then insert my extension's settings into the JSON blob.

So the examples that Firefox and Chrome provides do of course work, however they do not make very much sense to me. Why would it be formatted this way since all of those are additional key/value pairs and that is exactly what the registry excels at storing. So why put all of those into a single key/value instead of breaking them into multiple?

Additionally breaking them a part into multiple key/value pairs does work! So if instead of the example above I were to split them into multiple key value pairs it works just fine!

Software\Policies\Mozilla\Firefox\ExtensionSettings

   uBlock0@raymondhill.net
       "installation_mode": "force_installed",
       "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"

So knowing that this way with multiple key/value pairs works why am I bothering to ask this question at all instead of just doing it the way that makes sense to me? Well the issue is that by breaking it up into multiple key value pairs it actually overrides the other method and makes it so that all those registry settings are ignored. So it doesn't delete them but it still leaves me with nearly the exact same problem.

While I believe "my" way is superior because it uses the registry in a more common sense route, if that is not what the majority of extension developers do then it doesn't matter and I should be conforming to the other way.

As I am typing this question up I did realize just how hard/annoying it is to properly format and make it clear and digestible what the multi key/value format of the registry would look like instead of being a JSON string. So perhaps that is the reason why all the documentation puts it all as one JSON string?

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

Certain images are never created or loaded in my browser. Youtube thumbnails, for example, display as only light grey squares. I thought maybe my addons might be causing this, but the only one that seems capable is uBlock Origin, and I even disabled it completely. Anyone know what could cause this? Surely its a caching issue or something. I can include images if anyones curious.
