Forum der Gemeinschaft Firefox

Is there a way to remove specific stories from appearing? I'm Canadian and do not wish to see what the US President has done in these stories. Google News has a hide feature for specific keywords. Does Mozilla?

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?

I abhor the use of AI in the one browser I use because I thought it was far safer than any other browser. I have switched to Firefox because I knew it hadn't tracked my data, nor did it shove useless and unwanted features onto me without the ability to tell it no. But apparently, that has changed.

The blatant disregard for any opinion other than the CEO's in terms of including the implementation of AI tells me that Mozilla has little care for what their users want. Many people are speaking out against AI, many people here on these forums especially, and I am adding my own voice to the choir.

If the use of AI features continue to be added, I will consider simply switching browsers to one where I can at the very least patch out the AI entirely. I will be taking me, and my funding, with me, and I will not be looking back. I would hope these rising voices will be heard, and taken into consideration, before Firefox all but goes up in blazes and never reignites again.

Hi, i synced everything, in your browser, checked it few times, i had all my bookmarks from chrome to firefox few months ago, reinstalled windows, downloaded firefox and connected to account its clean, no of my information is there, wtf? i forgot the password, so recovered it. Give back my data for fuck sake, or it was mistake comming from chrome to firefox?

My browser has been acting off lately, it takes a longer amount of time than usual to even open gmail. Sometimes, it just fails to connect to a server and keeps loading forever and just stops (including gmail).

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.

Emoji in question: 👨🏻‍💻

Is there anyplace that shows how to use what the new release says on the 146.0. I got the message below when viewing new options in 146.0, but going to settings, sync just wants me to sign in and do a cloud backup.

Doesn't sound like what is in message below that I got after updating to 146.0. From what I found looking around, you are suppose to go to setting, sync, click on backup and choose location. There is no option backup, just an option to sign on. Below is message I got when checking what is in update 146.0:

Windows 10 users can now automatically protect their passwords, bookmarks, and more by turning on backup in Firefox. Your browsing data is saved daily on your device and can be encrypted with a password When you set up a fresh install of Firefox on any operating system for a new device or your current one, you can restore from this backup and pick up right where you left off. This feature is currently available on Windows devices and will be coming to other operating systems soon.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

I read article at: [https://support.mozilla.org/en-US/kb/.../firefox-backup?as=u&utm_source=inproduct#w_create-a-firefox-backup-file]

But in my up-to-date (or updated) FireFox, the restore backup by file option is appearing BUT enable backup or backup to file option is NOT appearing (screenshot attached).

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)
