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?

Is it possibile to change horizontal or vertical size of the main firefox window using mouse? Now I am able to open only one size between the maximum and minimum. Why? Mary

Whenever a Firefox extension connects to a particular native application for the first time, a dialog opens that looks like the attached.

I've pressed "cancel" on this prompt.

Where are the "privacy settings" I can use to revert this ? Nothing in the "Privacy & Security" section looks like it, and there's nothing in the "about:extensions" sections either.

I encounter PR_CONNECT_RESET_ERROR when accessing to some websites

mainly github google and stackoverflow

Sometimes "Reload current page" will work, with multiple tries

I am in China and I am using v2ray+v2rayA for accessing foreign websites (it is a necessity)

This issue happen only on firefox, as edge and chrome can access without error

Is there some settings to disable the PR_CONNECT_RESET_ERROR feature?

Will Firefox ever be updated to use end to end encryption so that users of Facebook Messenger can do audio and video chats as they did before META's change?

If not, Mozilla could lose a lot of Firefox users of Facebook Messenger. That includes me. I have been with FF since v0.93 :-P

Messenger audio and video chats work fine on several other browsers including Brave. There is even a Messenger App on the Microsoft store.

I would really like to see someone at Mozilla answer this.

I've followed all the steps for updating Firefox on Linux, but every extension prompts me to update when I go to add them. How do I know when Firefox is really updated? I access Firefox through Linux on a Chromebook, in case that helps.

I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

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)

I have changed operating systems from windows to linux mint. I made sure to sync my profile before uninstalling, but now the profile looks to be empty. there are no saved passwords or bookmarks. This worked when I changed between different windows devices last year, but this time it seems stuck. I will check on a windows device when able, but in the meantime, are there any other ways to troubleshoot this?

Is it possible to click individual segments of an URL in the address bar to navigate there directly (without manually selecting and deleting the tail)? It's a convenient way to reach upper layers of a website.

For example Vivaldi implements it via Ctrl+<Mouseover/click> (see attached screen capture)

Is there an option or addon to enable this? Thanks in advance

(In reference to [post] where it said "This thread was archived. Please ask a new question if you need help.")

Why isn't there a simple means to remove/prevent searches for the address bar, using config doesn't work.

I've used Firefox for over twenty years, this annoyance will end that and force a move to Brave.
