Can very old language package files in C:\ProgramData\O949 be removed without causing problems?

Hello all,

During clean-up of my laptop I noticed 31 language package files in C:\ProgramData\O949. File names look like: langpack-en-US@firefox.mozilla.org, and they all originate from 23-Jan-2017 so I guess they're very old files which might be relevant anymore. As these 10,058 files occupy 56 MB I'd like to remove them from my laptop.

Does anybody know if such task is wise, not harming current running FF v131.0.3?

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

I need Firefox up and running in order to access the application for which was the intended use of this container. However the lightweight desktop apparently doesn't have some of the services running like systemd and snap. There is a binary named "Firefox" already installed at /usr/bin/firefox but I've tried "systemctl start firefox" but that didn't work. Any ideas on how to get Firefox up and running? Thanks Norm

Hi, I just finished writing a few lines of javascript to automate bookmark management. I tested my Addon using about:debugging > Temporary Extensions, and now I'd like to keep the extension loaded across firefox sessions.

What is the best process for doing this? I attempted to create a .xpi file but when installing via "about:addons > Install addon from file" I get the message "This addon could not be installed because it could not be verified".

What is Firefox's self-signing process for this? I don't want to have to install dev versions of the browser just to automate one task.

How much longer will Firefox be down due to server updates on Mozilla.org? ALL of my extensions are disabled for that NLT 15 minute update that's been going on for well over an hour (I know, because my extensions are still disabled and have not yet reset themselves---Mozilla crapping them out, Mozilla returns them to my setup---to the way I had them configured. Specifically, the ones I'm missing the most right now are Tab Sidebar, Tiled Tab Groups, and whichever one(s) make bookmarks/new tabs open in a NEW tab, not clobbering a tab that is currently in use. I did that to open Duck Duck Go a minute ago, and had to re-write this whole support question because, for some reason, Duck Duck Go opened up in this ACTIVELY IN USE tab instead of a new tab. And not only that, it wiped the contents of this support chat window. Sorry, but that is totally UNSAT.
