Hi everyone, I’ve been using this browser for years—it’s my favorite. I recently ran into a problem: I reformatted my PC and reinstalled the browser, but since I’d been using it for so long, I had forgotten my password. I managed to recover it by sending an email to my primary Gmail account, but upon logging in, I discovered that I’ve lost all my stored passwords. I would appreciate it if you could help me by explaining the process to recover them.

Hola, amigos, he usado el navegador durante muchos años, es mi favorito. Recientemente he tenido un problema, y es que he formateado mi PC y vuelto a instalarlo, pero de tantos años que tenía, había olvidado la contraseña. La volví a recuperar mandando un correo a mi GMAIL principal, pero al ingresar resulta que he perdido todas mis contraseñas almacenadas. Les agradecería si me ayudaran indicándome el proceso para volver a recuperarlas.

Tengo como página de inicio el calendario de Google, desde la ultima acualizacion no me permite modificar, cuando cambia el mes Anteriormente figuraba por ej 2026/06/01 yo cambiava 06 x 07 y me mostraba el mes en curso

Hello everyone,

I'm experiencing a strange issue with Firefox's Add-ons Manager, and after several troubleshooting attempts, I'm out of ideas.

I performed a completely clean installation of Windows 10 LTSC. Before installing Firefox, I only installed the drivers that Windows installs automatically for my peripherals. I didn't install any third-party software, tweak utilities, antivirus, or anything else.

I then installed the latest version of Firefox, and I noticed the following problem:

From the Add-ons Manager, I cannot open any extension in a new tab.

I've attached screenshots to show the issue.

The extensions themselves work perfectly. I can install them, configure them, enable/disable them, and use them without any problems. The only thing that fails is opening an extension's details in a new tab from the Add-ons Manager.

The issue occurs both when:

- Middle-clicking an extension. - Right-clicking an extension and selecting "Open Link in New Tab."

In both cases, Firefox opens a new tab displaying the following error:

«Firefox can't connect to the server at "addons://detail/[extension-name]".»

I originally noticed this during a previous Windows installation, so I assumed I had broken something while tweaking the system. However, after trying the common solutions I found online without success, I decided to perform another completely clean installation of Windows.

The problem is still present, even on a fresh Windows installation with a fresh Firefox installation.

To rule out Firefox Sync, I also deleted my Mozilla account before reinstalling Windows. The screenshots and all the tests were performed before signing in to any Mozilla account, so no settings, extensions, or preferences had been synchronized.

Has anyone experienced this before or knows whether this is expected behavior, a Firefox bug, or something else?

Any help would be greatly appreciated.

One additional thing I noticed:

Immediately after installing Firefox and launching it for the first time, the Developer Tools opened by themselves without me pressing any keyboard shortcut or changing any settings. They opened and closed on their own for a short time, and then never happened again.

The exact same thing also happened during my previous Windows installation, before I decided to perform a completely clean reinstall.

I'm not sure if this is related to the Add-ons Manager issue, but I thought it might be worth mentioning.

Hi, After the update to the version 152.0.4 RC, the options and other topics only shows in English. I'm configured in Spanish*ar.

Also the main menu alternate in different sessions beetween both languajes.

Thanks.

Desde hace unos días se cierra mi pestaña al poco tiempo y me indica que la vuelva a recargar. Tengo Windows 10 64 bits y Mozilla está actualizado a la última versión. Abajo estan los reports de error que también les he enviado. Espero alguna solución. Gracias.

La ultima actualización de Firefox arruinó mi trabajo. Trabajaba con varias ventanas abiertas y cada vez que abría Firefox aparecían todas sin ningún problema. Hoy 17 de Junio abrí Firefox y ya no estaban todas las pestañas con las que estaba trabajando, y al contrario aparecieron unas 6 ventanas de hace meses. Debe haber alguna forma de recuperarlas. He intentado varias y no he podido, o todo me manda a ver el historial o me hablan de Marcadores, cuando lo que quiero es recuperar mis pestañas. Y no recuerdo la mayoria como para hacerlo manualmente, sin mencionar lo laborioso que puede ser, y tambien el tiempo que me han hecho perder y sigo perdiendo.
