Firefox 社群討論區

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'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.

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

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

I have Privacy & Security set to Strict with Cookies and Site Data deleted when the browser is closed with only 3 sites in the exclusion tab. I also use a VPN to assist with masking and for connections to defined systems and as part of that I will randomly set it to different countries 'because I can'.

I was looking at the website for the current Rugby World Cup (https://www.rugbyworldcup.com) but it was showing the wrong times for the matches. A little digging showed it had remembered my location from some point last week when the VPN was active and set to Iceland.

There is nothing I can find in my browser settings to permit this and I would appreciate pointers to check further since one of the reasons I have set the higher level of restrictions in my browser is to stop this kind of activity from websites.

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 have spent hours with Tech department and digital assistand department at Directv. Today they are telling me as long as I use Firefox I will be unable to access my account. I have paid to have my computer checked out and was told that it was updated and the system was working fine. How to I get Directv to recognize my system?

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?

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.

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
