Komunitné fórum Firefox

When trying to log into my work Microsoft Office 365 account on Firefox, a QR Code is supposed to appear, which I scan with my phone and the MSFT Authenticator app logs me in. This doesn't happen in Firefox but instead says, "Touch your security key to continue with login.microsoft.com. I am not using a security key and they are not allowed by my work. This works fine on Chrome based browsers.

Is there some setting that will fix this or is this a bug with Firefox?

Recently upgraded to version 146.0 on Linux (Mint, Cinnamon)

YouTube will work fine when I first start the browser. Eventually videos will stop displaying and sidebar links will not be active.

From a separate forum article I cleared all site data and restarted Firefox. That fixes the problem for about 4 or 5 videos, then you need to rinse/repeat.

The latest incident seems to have been triggered when I tried to watch a video embedded in an X (Twitter) post. That failed. And the YT failed as a whole. X was open in a separate tab container at the time.

While I have both Privacy Badger and uBlock Origin installed, both are deactivated for YouTube.

See the attached images. The video is just not displaying, though the screen is reserving space for the player.

Both/all videos I have tested do work in Chromium.

To whoever this new CEO is of firefox,

Stop with the AI garbage. Please.

AI is a notorious waste of space in software and all it does is bog down the experience and make everything harder for everyone. Also it is notorious for collecting information and violating users privacy like the lab rats you apparently take us for.

Stop it.

I loved Firefox because I could use it comfortably without all of this stupid AI crap making my life harder. I've already hacked my browser to make sure this doesn't appear but I'm not satisfied. To any other firefox tech reading this get that Anthony guy out of here. We don't want him, and we don't want AI.

Thank you.

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Untill latest update when on a site was link, ex. http://site.site/repository/text.txt i could select the link and from context menu select "open link in new tab/window" or "save link as". Now only "copy link" action is available. Im on Ubuntu 24.04.3 LTS Thanks for any response.

If Firefox becomes an "AI browser" as it's new CEO says I will switch to another browser. The privacy and environmental problems alone are enough for me to warrant this change, to say nothing of how it's slowing the browser itself down and making it worse. I'm sick and tired of AI shoving itself into every single aspect of life, taking things that already worked fine on their own and making them worse for no reason, in addition to ruining the planet and encroaching more and more on the privacy of everyday folks like myself. Anthony Enzor-DeMeo's insistence that we should "trust" this hypothetical version of the browser is frankly sickening, and everyone involved in this scam should be ashamed.

Anthony Enzor-DeMeo wants to push way more AI onto Firefox. I originally became a Firefox user for the customizability, privacy, and security it offered in comparison to other browsers. How does Mozilla Firefox intend to maintain these features with so much AI slop? Will there continue to be versions of Firefox available without the AI components? I'm sick of having to turn off new data-stealing AI settings all the time on a browser I once trusted. I hate that I am now looking for other options.

This isn't so much a question as a complaint, I guess. Get your shit together, Firefox!!!

I wish Firefox would realize that when working on this machine I am at work and my laptop is personal. I now have too many work things registered under my personal email. I am considering no longer using FireFox because the browser can't seem to be cognizant of work vs. personal.

I installed firefox on ubuntu 24.04 following the guidelines from https://support.mozilla.org/en-US/kb/install-firefox-linux

I followed the direction from the section "Install Firefox .deb package for Debian-based distributions", adding the https://packages.mozilla.org/apt repository, prioritizing that over firefox snap from ubunto repors and finally installing firefox.

All good, now I have the latest firefox.

Question: what entry should I add to the "Unattended-Upgrade::Allowed-Origins" section of "/etc/apt/apt.conf.d/50unattended-upgrades" in order to enable unattended upgrades for the mozilla repo?

Googling this got me different contradictory recommendations that did not get my system to firefox 146 until I manually run the apt update/upgrade.

Thanks!

I've been using Firefox for years because more popular browsers like Chrome and Edge have anti-features I dislike. In recent years, however, it feels like Mozilla has been more eager to follow trends set up by it's larger competitors even when those trends seem destructive to the principles that used to be at the core of this project. AI is the final straw for me. I don't understand why I would even use Firefox over Chrome if both are full of AI anyways. Even if AI wasn't a deal-breaker for me, I'm worried Firefox will make similar decisions later. I want out.

Is there any good and maintained alternatives to Firefox? Something like how Firefox was just a handful of years ago? Maybe a fork of an old version?

I'm getting seriously sick of the AI "features" Mozilla keeps adding to Firefox. I use Firefox primarily for its privacy and to get away from AI! If it doesn't stop, I'll have to start exploring other options.

I was positively surprised recently when the new Firefox profile manager (about:profilemanager) was introduced. https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/ is an article about that.

However, I thought it's just a new visual UI with an in-browser switcher for the existing profiles (that I already had setup). However, it does not appear so.

The differences I see:

1. 1. 1. old profile management

• was managed by `about:profiles` or when starting FIrefox with `-P`
• is saved in `~/firefox` and the `profiles.ini` clearly and quite obviously mentions them there, so it's easy to manage them.

I also found this old support article: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

1. 1. 1. new profile management

• automatically asks on startup if more than one profile exists
• is managed by `about:profilemanager` or with the Firefox burger menu
• seems to be saved in `~/.mozilla/firefox/Profile Groups` (Linux path here) in some .sqlite files, and I do not quite understand the format. Not mentioned in `profiles.ini`.
• also, when you change something here (even like opening a profile?), you cannot open `about:profiles` anymore, because it says "Some Firefox process has made changes to your profile, […] you need to restart Firefox", only after a restart further changes would be possible, which I find quite confusing but it also indicates somehow the features belong together?

And this seems to be the new one: https://support.mozilla.org/en-US/kb/profile-management#w_whats-the-difference-between-profiles-and-multi-account-containers

1. 1. Questions

• What are the differences here (I may have missed)?
• How can the new profile feature save so few files? Is it technically called "profile groups"?
• And the most important: How can I migrate an old profile? (In order to use the new features and GUI etc. I quite like)
