When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

For information: OS: EndeavourOS with Linux 5.15.94 DE: Xfce 4.18 with Xfwm 4.18 Version: Latest, Firefox 110, installed from Arch Linux repository

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

Hi,

first of all thank you all in the community for your amazing work on Firefox!


I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905


Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

  • The file extension and file type are absolutely mp4.
  • There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

Hello,

After installing Firefox (103.0.2) on a clean install of Manjaro (21.3.7) Gnome (42.4), I started noticing that mouse hover effects such as highlighted tabs, UI of a video-player appearing etc. are delayed after my PC exits hibernation (I am not sure if that is the only cause and if that really IS the cause). Weirdly enough the select menu I used to answer the "Which topic best describes your question?" question to create this post experiences no delay in highlighting the hovered element. Relaunching Firefox fixes this issue temporarily.

To be clear this is no performance issue since everything except mouse hover related interactions are fluid.

Thanks for helping out

Weird (indirect?) scroll via touch pad

Machine information: OS: Manjaro Linux x86_64 Host: 80TG Lenovo V110-15IAP Kernel: 5.19.1-3-MANJARO DE: Plasma 5.24.6 Xorg WM: KWin CPU: Intel Celeron N3350 (2) @ 2.400GHz GPU: Intel HD Graphics 500 Firefox: 103.0.2 (x64)

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

  1. Download Firefox and another application with direct input (Opera or Telegram for example)
  2. Scroll Firefox
  3. Scroll another application

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?
