Hi,

I am currently working on a privacy study regarding Mozilla Firefox and I would like to have more detailed information on key log file using per-session secrets.

I used SSLKEYLOGFILE environment variable from underlying NSS library to get TLS session secrets [1], which can be used in Wireshark to decrypt HTTPS traffic. I looked at Firefox documentation for some answers and I found that NSS support for logging file is disabled by default since NSS 3.24 [2], that-is to say Firefox 48 and 49 [3]. I do not have found any documentation saying it has been re-enabled by default since then. However, I have made some tests on Ubuntu 22.04 LTS (it is disabled on Debian) and Windows 10 using Firefox 106 (NSS 3.83) [4] and it works properly.

So, I have two questions : - Is it normal that this feature still works for decrypting traffic whereas it should be disabled by default ? - What is the position of Mozilla developers and the community on the security of this feature (anyone who have access to someone computer could get all of their internet passwords) ?

Thank you for your reading and I am looking forward to reading your answer.

Best regards

On my personal home page, I have several links as in the subject: which I use to browse javadoc. Clicking on the link does nothing AFAICT. Is there some kind of configuration setting to get the "click" to work? (It used to work years ago)

There are some workarounds

Workaround One

  1. Copy Link (context menu action)
  2. Ctrl-L
  3. Paste link in search/open bar
  4. Return

Workaround Two

  1. Open Link in New Tab (context menu action)
  2. Click on New Tab
  3. Ctrl-L
  4. Return

Workaround two leave an unwanted open tab

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

I disable my option "Restore previous session" and it works fine if i close my firefox.

But if i do not close my firefox and reboot my computer directive, the session will restore at next startup.

Obviously when i reboot my computer, I don't want to see my tabs anymore, but I failed to find any setting to do so. I also find someone say to set `browser.sessionstore.resume_from_crash` in `about:config`, but it doesn't work, and I don't think it is the proper way to solve this problem because reboot is not crash.

When installing Firefox, there is an option to import data from another browser. That feature is also available in the "Library -> Import and Backup -> Import data from Another Browser", and it imports things like Bookmarks and History from another browsers.

As the functionality already exists, is it possible to use that functionality in any way to import Bookmarks and History from a different profile in the same Firefox installation? I want to merge 2 different browsing history (like the old question https://support.mozilla.org/en-US/questions/928204), and looks like using the "Import data from Another Browser" could help if it's possible to use it with another Firefox profile/directory.

Since Firefox moved to Snap updates, two things have happened almost every day: Snap pops up to say Firefox has an update pending, and it wants to be closed and restarted; and tabs crash, and the only way to make them stop crashing is to restart Firefox or restart the OS.

I suspect the two problems are linked, and I really have to ask: do we have to have an update every 36 hours? Microsoft mostly gets by with one update cycle per week. I like to use software, not update it. I know it has to get updated regularly, but regularly shouldn't be the same as constantly.

Environment is: Firefox 106.0.5 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0 Ubuntu 22.04.1 LTS (64-bit) GNOME version 42.5 Wayland windowing system

How to remove duplicated entries in history only differenced by URI fragment

When navigating in some pages, specially in google docs, the browser's URI fragment (the part after the #) changes frequently for each page/header/slide, and all of them are stored in the history.

That behavior adds lots of entries in the history and also hinders the usage of the search functionality of the address bar (as all the duplicates are shown instead of shown only one and other pages). I want to keep one entry per document, at least in specific pages like gdocs where the "fragment" doesn't add any useful information and each document can have lots of them.

Is there any way to configure that behavior, to not save every fragment in the history?


To reproduce the above behavior (the same behavior happens in other pages, not only gdocs):

- Open any gdocs document with several headers, or a gdocs presentation with several pages. - Navigate all the document/presentation, and check the history. - Close the document/presentation tab/window. - In a new window/tab, use the address bar to search the document/presentation by the document name: several entries for the same document/presentation are shown (and if they are lots of them, no other different entries with same words are shown in the address bar). - Check also the history: several entries of the same document/presentation are shown (it could be hundreds for long documents, and thousands after seen few documents).

New Tab Override extensions also doesn't helps, because of restriction for extensions to use full javascript. It gives the error: Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).

So these days mozilla crop. actually totally blocked the ability for users to use their own files as their own new tab, and blocked for extensions to access local files or full-functional javascript on their own pages, which is not just ridiculous but malicious.

So how can i use my local file with full-functional javascript as new tab?

When Firefox is running and I lock the screen and unlock it again, the gui seems to be somehow broken. On the picture attached one can see a graphical issue (black frame) on the right side of the browser when resizing the window. When I try to make it smaller starting from the left, the window disappears inside the black frame on the right side. There are also issues regarding the mouse. It is not possible to see which part of the text is already selected when pressing and holding the left mouse button during text selection (no orange highlighting of the text). When I release the left button the text is selected.

This is the second PC with Ubuntu 22.04 where this happens. Both PCs were upgraded from Ubuntu 20.04, so maybe it has to do something with that.

FireFox: 107.0 (64 bit) Mozilla FireFox for Linux Mint OS: Linux Mint 21 Cinnamon

Issue: On this FireFox latest version, the download window cannot be resized to smaller than (roughly) 1/4 of entire screen. (screen-shot attached.)

Attempted: Mouse left-click grab of all corners & sides to drag window smaller - failed!

Note: Download window can be resized *bigger*, showing this window has now been coded with a very large minimum size that is almost 1/4 of full screen

- this was not the case in previous versions.

Micro-annoyances add up, people switch to Chrome (sorry to use the "C" word!)

Linux Since the last 'automatic' update, Firefox hangs when started, but doesn't show any GUI.

Many experiments later, I can report the following progress:

- I started firefox from the command-line, hoping to see some output (no luck there), and eliminating problems with the window manager launcher (XFCE) - Firefox launches, but in triplicate: 3 instances are running (of firefox, _not_ firefox-bin) - There is no console output. - Running inside gdb shows threads entering and exiting, no errors. On ^C, there's just a message about exiting the current thread. - If I kill two of the instances, the GUI appears, so it seems they are blocking each other - I wanted to trace the startup sequence, so I did `strace ./firefox 2> log` and behold, firefox started! This is why I am reporting this on the actual started firefox. - Which makes me suspect a 'race condition' - surely the strace is slowing things down, allowing one instance to create the GUI. Some code which is not lock-protected?

I'm afraid this could happen again in next session, which is why I report this first, before trying to restart FF.
