The following content is machine translated: The passkey feature (login via QR code scanning with a mobile phone) is not available the Linux version of Firefox. Compared to Windows and macOS, the Linux version does not have a passkey option when logging in; it only has a "security key."(as shown in the image) I cannot use the pass key saved on my iPhone to log in to websites, which is very frustrating. Is this a bug or an incomplete feature? Thank you for your reply. device: archlinux

Untranslated (chinese) : 通行密钥功能（通过手机扫描二维码登录）在linux版的firefox上并不能使用，相比windows和macos，linux版在登录时并没有通行密钥选项，只有一个“安全密钥”（如图），我无法使用保存在iPhone上的通行密钥来登录网站，这很令人沮丧，这是一个bug还是没有完成的功能？感谢您的回复 设备：archlinux

This may be an old problem. In Linux, in bookmarks library, the scrollbar thumbs behave differently than in browser web pages. Even in new profile. This isn't a new issue for v157. Same behavior in any theme (any Fx themes, and / or diff 'Nix system themes).

I set scrollbars to disappear when not used or being hovered. On sites, when hover scrollbar area, they reappear. AND while pointer is over the track or thumb, it remains visible - does not reduce to an unusable width or disappear completely. As I think it should.

But in bookmarks library, the track & thumb disappear, even w/ pointer hovered, unless thumb is grabbed immediately. Even grabbing thumb & move it, then pause a fraction of second (still gripping thumb w/ L mouse button), the thumb & track STILL disappear. As long as you don't release grip (on now invisible thumb / track) they reappear when move pointer.

The bookmark library scrollbar behavior is also erratic. How long you have to grab it, when you 1st hover it. If you accidentally move pointer from folder pane, past vertical divider into bookmark pane, then left - back into folder pane, the scrollbar doesn't appear.

You have to move pointer well left of scrollbar, then approach it from the R, to make it reappear. It doesn't have any of this behavior in the browser (never has, AFAIK).

An 8 second delay when I open Firefox for the first time.. Once it has been opened once, it reopens immediately when required. The problem has been present since I installed Linux Mint 9 months ago, Linux Mint 22.2 then, since upgraded to 22.3 Zena. I can live with it, but it is very frustrating! I have tried the obvious things like removing extensions, but I suspect it is a "Linux" connectivity problem rather than a "Mozilla" problem.

Currently on Linux, but the problem is probably not OS-specific (although any work-around may be).

What I look for:

I want one setup for work, one for union, and one for personal use. If my work setup would be compromised, union bookmarks, search history etc is not compromised at the same time. Also, my work setup is not cluttered with private bookmarks and addons. Obviously, it'd be nice if those setups could be handled as separate start menue icons, so that I don't need to switch using a couple of clics, but just start the right setup directly. Needless to say nowadays, that these setups need to be syncable between devices. Ideally I as a person would have one Mozilla account that can store multiple profiles and protect each one with a seperate password, OR I as a person would have multiple Mozilla accounts that are made for easy switching.

What I've tried:

Multiple accounts, obviously; they sync between devices, which profiles really do not. The problem I run into is that I still need a separate profile for each account if I don't want to log in and out of them (which I don't want indeed, Alt-Tabbing during my leisure time is the only way for me to get things done for union and often for the office-part of work).

Finding the profile feature was hard enough but I adopted and have the about:profiles page bookmarked in all profiles. But whenever I start using a new computer, I need to set up new profiles. I tried saving them in a custom location on my nextcloud so that they can sync, but there is no straight forward way to import profiles. You need to create new ones and then move the contents of the old ones, instead of just pointing ff to an existing profile; that kind of kills the point of picking a custon location in the first place. All I ever do with a new profile is logging in to one of my already highly profiled accounts.

Along the way I realized that there is a now more GUI-way to create profiles, so I tried that. But when I tried choosing a custom location for them, I failed. Took me a while of restarting and googling to find out that Mozilla has managed to have two completely seperate features with the exact same name! That is, when you create a profile the modern way, it does not appear in about:profiles and vice versa.

Since I ditched the idea of custom location anyway, I setteled with the new way. But when I thought I'd make seperate startmenue links for them, because surely you can handle that with some kind of flag in the command, I could find only one option for profiles, and, as you can guess, it works with the old profiles.

It seems that one can start with a profile at a certain path, so maybe the old way with custom path could be something for me anyway, but when I used such a profile, I got a warning message that says that history and bookmark functions might not work properly and that some security program may cause this.

So, how is one actually supposed to use different accounts OR how is one supposed to sync different profiles between devices?

Hello! I am having trouble restoring my old Firefox profile after migrating my system from Windows 10 to Linux (Fedora). I have a backup file in .html format that is 197 MB in size (originally created on Windows). When I try to select and restore it using Firefox's built-in recovery tool, it throws an error: "Something is wrong with this file. Please try again with a different file." What I have tried (and what didn't work): Moved the file from an external drive to the local Linux Downloads folder (the error persists). Tried dragging and dropping the file directly into Firefox (the recovery page loads, but the restore buttons are missing or inactive due to security/script restrictions). Tried renaming the file extension from .html to .zip to extract its contents manually, but the archiver threw a "Not a zip archive" error. The built-in recovery script fails to process a 197 MB HTML file, likely due to size limits or memory handling on local files. Could you please advise on how to properly handle and restore such a large backup file or extract my data (passwords, history, bookmarks) from it on Linux? Thank you in advance!

Recently I updated to Firefox 157 and expected the newer New Tab UI to appear, with widgets and the like. But instead, it is displaying the older New Tab UI, without the new widgets. I don't want to create a new profile and have to start over with all my extensions and the like so what can be done in this case?

I'm trying to use Firefox Backup and have it save my sensitive data, but every time I enter a password, even if it meets the requirements, I get an error banner: "Something went wrong. Please try again."

It's very frustrating that the error message is so unhelpful. I have no idea what went wrong, nor how to fix it -- just trying again results in the same thing.

What is happening? How do I fix it?

How can I make sure the Vertical Tabs sidebar stays visible in full screen mode?

It worked this way by default until the [154.0 release](https://www.firefox.com/en-US/firefox/154.0/releasenotes/#note-792047):

> Fixed the Vertical Tabs sidebar staying visible in full screen mode. It now hides along with the toolbars and reappears when the cursor moves to the edge of the screen.

Is there a config setting that re-enables the old behavior? I want the address bar to be hidden in full screen mode, but not the Vertical Tabs sidebar.

I open Extensions and I can't find my extension so I open manage extensions and it shows but it's not letting me use it the image that is roblox unfriender is the one not showing up and the picture of 2 extensions is the ones showing up don't roast me I'm a new user

I have st installed Lime on my old Asus Zenbook an have installed Nord VPN. I am using the Firefox browser showing connected to the internet but am unable to access my webmail account and its popping up messges advising Problem loading webpage and another showing 502 Bad gateway. I am also having problem with the Zenbooks Keyboard with keys randomly not operating when pressed but will work after a prolonged or multi pressing.

My Firefox browser has just been updated .. not by me but somehow .. to 140.11.Oesr(64-bit) Its completely messed up all my settings .. why? Its taken me the best part of this morning to sort everything out . All my bookmarks were not displayed, the web pages that should have been displayed on startup weren't.. and to cap it all the "Done" button is hidden at the bottom of the page .. and why is it needed  ? all other setting just need to be changed to set them. Its so annoyed me that I've downloaded Chrome. and I'm using Opensuse Leap!

Hello,

I am trying to further secure my Mozilla account and was delighted to see that they added support for passkeys. I am signed into my Proton Pass on Firefox addon, but Firefox does not seem to understand it is supposed to create the passkey inside Proton.

This is unlike behavior I have witnessed on other sites supporting passkeys which has worked flawlessly to set up, such as Amazon.

i don't think you can you've fallen into the secure everything at the cost of your consumers going top Google chrome or Brave or etc just not firefox. It used to be my fav not any more congrats on your fuck up

This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing.Learn more i tried add froxyproxy standard the above is what i'm getting

all tabs failing to play; is this a profile grep e unlock issues; GROK 5 linux ubuntu link action: terminal commands: ps aux | grep -i firefox ; kill -9 those PIDS; is the number one cause of firefox silently failing to relaunch after a hard kill
