Firefox: форум сообщества

I have a local file I wish to view in firefox without starting a HTTP server (it's only docs for a crate I'm building) however Firefox is unable to open the file despite the file existing and having correct permissions. The file was in a separate mount (disk) to where Ffox is installed so I copied to to /tmp/ to remove that as a variable but still no joy..

➜ ~ file /tmp/index.html /tmp/index.html: HTML document, Unicode text, UTF-8 text, with very long lines (3556) ➜ ~ ls -la /tmp/index.html -rwxr-xr-x 1 ben ben 4208 Dec 30 14:04 /tmp/index.html

Am I missing some new setting which allows local file browsing using the good old 'file:///' protocol?

Thanks, Ben

OS Info: PRETTY_NAME="Ubuntu 24.04.3 LTS" NAME="Ubuntu" VERSION="24.04.3 LTS (Noble Numbat)" VERSION_CODENAME=noble

F/Fox version: 146.0.1 (64-bit)

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.

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.

I can not open : www.mobile.de What is here going wrong ??

Access denied  ?? I cannot understand this ?? Thanks for help, rainer banspach

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.
