"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 ```

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

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.

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.

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.

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.

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 ?

Hello

I'm trying to sign into a Microsoft 365 email account but can't get beyond a screen saying "To use this site, you need to change your browser settings to enable DOM storage or cookies."

I've enabled DOM storage and cookies but no difference. I've cleared cookies and no help. I'm running Firefox 115.0.2 and Linux Mint.

Is part of the problem that I hate Microsoft and they know it?

Thanks

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?

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.)

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?

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help


Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

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

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"

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

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.
