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.

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

In my firefox the file input is not functioning at all.

EX: I go to https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_type_file and try and use any of the file inputs there - they just do nothing.

Same with the file inputs on this support form page. None of them work for me.

System - ubuntu22.04, ff: 106.0.1 64bit

Idk why but sometimes firefox just doesn't prompt to generate secure password, I even have to download some extensions to generate secure password (Secure Password Generator) meaning more secure issues.

My guess is that you guys probably hardcoded something like {if "type: password" then prompt}, but it's still partly fault at developers too for bringing these huge chunks of javascript.

In screenshot there's element examaple in which i input password but no prompt whatsoever.

Previous versions of Firefox allowed scroll wheel button clicking to open links. I noticed that the latest version doesn't allow this. Ctrl + left click works as normal but not the scroll wheel clicking.

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

I am running Firefox on Mint Debian edition, I find the Youtube playback very low volume preset at about 1/4 of max, I try set it to the max but it returned the same after restart. I start FF in trouble shooting mode to disable theme and extension but didn't change thing, I remove and reinstall FF also did not help. I find something strange that, on the Help menu it said the updates disabled by system administrator but I did not do that, it is now on 116.0 64bits, any comment ?

I have several machines on my local network. I work on machine A, and run applications remotely using ssh -X on the other machines. Today I discovered that when I start Firefox on newly-upgraded machine B, it's actually starting the older version that's on machine A. This seems obviously wrong, and is certainly not what I want to happen. I want to run the newer Firefox that's on B, and have it display on A.

Longer details: A runs OpenSUSE Leap 15.0. B runs Leap 15.4. I start an xterm on B with the command " "ssh -X -l me B", and programs other than Firefox I run from that xterm display on A's monitors, as expected. However, when I try to run Firefox (by typing "firefox &" on the command line, what actually runs is the older version of Firefox that is on A, just as if I'd started it with the same command on one of A's terminals.

Is this a known behavior, and if so, is there a way to work around it? Or am I just doing something really stupid?

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

Selecting text on any page, there's no visual feedback of what is selected until mouse is released.

There's no feedback that selection starts when mouse button is pressed down, no visual feedback while moving the mouse with the button pressed and only upon releasing the button do I get to see the selection.

Selecting works fine in other browsers (chromium) and was working the other day before I did a fresh install of Ubuntu 22.04 (was using 20.04 before) wiping my previous Firefox. So this issue is on an almost vanilla Firefox version 104.0.2.

(Incidentally I can highlight that version number and only that version number in the about-box and I get continuous dynamic feedback of what part of the version number I highlight, but nowhere else in Firefox.)

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

A long time ago, I saw a list of open tabs in all windows, not just in one window, as it is now. (By the way, Google has added such a feature to Chrome. Clicking on the arrow allows us to see any open tab and navigate to it.) I am currently using Tab Manager to search for a tab. But the tab manager is not the best option because it is too slow to open and requires too many resources. Can I restore the old behavior to see tabs in all windows?

OS - Ubuntu22 Firefox - Default firefox on ubuntu22 (Mozilla Firefox 103.0.1)

Use case - 1. Custom profile folder (named prof1) contains pref.js and chrome folder with custom css file. 2. prof1 is created in -> "/customData/profiles/prof1" 3. The folder "/customData" has full rwx permissions and is owned by $USER (not by root)

Output -> 1. When launching firefox mentioning the profile -> "$ firefox --profile /customData/profiles/prof1"

The browser does not load, but there is an error box saying Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

Questions -> 1. Is it possible to load firefox profile from root directory ? 2. If custom profile folder is created in "/home", then it is launching and working perfectly. How is this possible when the permissions and owner is same as the one in "/customData"

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj

How to do

Since a recent update the spacing of words in Firefox's UI as well as on some websites seems to be wider than normal (instead of a singular space it seems as if each space is now a tab wide). Additionally the numbers have also suffered and are now not presented in a normal font anymore but instead seem bigger and grey instead of white or black. Both of these issues occurred at the same time and appear on the normal User Interface of Firefox (e.g. in the bookmarks or in Firefox's settings and preferences) as well as on some websites/search engines. However when copying the text and numbers from Firefox into a regular text editor everything seems normal and no appearance issues can be noticed. What I've already tried: I've restarted my system multiple times since the issue first occurred. I've removed all contents from /home/user/.mozilla/firefox. I've reinstalled Firefox. I've deleted my cache. I've changed my font preferences in Firefox back to Default(Roboto) after having used Inter before. None of my actions above have changed anything. However, when I log into a different user on my computer and open Firefox there everything seems to be normal, so it seems as if this is a user-specific problem.

Thanks in advance, Emma.

Hi,

I'm on an a pretty old Linux Xubuntu pc, but with the latest FireFox. In a profile I regularity use I unchecked the Title Bar checkbox in the Customize Toolbar screen, but then FF crashed and I can't get that profile opened again. I can still open other profiles (because I still use the old-fashioned profile manager and don't need to go into about:profiles), but when I open that particular profile, after some hangups, I only get FF in the taskbar, but no screen opens so I can't change the setting back again.

Is there a file in the profile folder I can edit or something like that to enable the Title Bar option again to see if that profile wants to open normally again?

In case that's not possible I can copy that particular profile into a new profile, but then I will undoubtedly also copy the title bar setting, which I don't want. So can I copy the profile except for the one file with that setting and use the file from the new profile instead? What file would that than be?

I hope someone can help me out. Thanks in advance for any help.

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?
