Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.

Good morning,

I'm reaching out to see if I can get some assistance with Firefox on of our network. I'm System Admin at Goodfellow AFB. I've tried searching this issues on the web and found similar issues but solutions that were recommend online have not worked for us. Yes I have uninstalled Firefox completely and installed it from scratch. I know it has something to do with autoconfig file but not sure what exactly I'm looking for. Thanks.

I am trying to reach an internal company website (www.gqma.drw), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust www.gqma.drw because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate ~~~

If i click on the error code, i get these details:

~~~ https://www.gqma.drw/

Peer's Certificate issuer is not recognised.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false

If i click 'View Certificate', i get a chain of three certificates:

  1. Subject common name = *.gqma.drw, issuer common name = SSDNS CA, subject key ID = BE:EC:EA:22:CD:4E:D6:2A:07:4F:7A:85:FA:89:52:67:77:43:B1:E1
  2. Subject common name = SSDNS CA, issuer common name = ISS Root CA, subject key ID = 8C:60:FD:78:C7:B3:FD:59:0B:73:99:E5:36:48:3F:53:A7:41:82:65
  3. Subject common name = ISS Root CA, issuer common name = SS Root CA, subject key ID = 80:DD:C6:A2:AC:82:4F:FE:8A:19:2E:AA:EA:F8:BF:61:48:DC:31:73

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the SSDNS CA and ISS Root CA certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

We have Firefox-ESR in use and we are using Applocker.

When we enable applocker dll Rule policys and start https://shaka-player-demo.appspot.com page clearkey addon crashes.

We have allowed widevinedrm.dll in applocker rule policys, and we have used Process Monitor to track which dll file / files are being "locked" but we cant seem to pinpoint it.

Where does Firefox-ESR run DRM content and which dll files are needed to run ?

What we know that it is caused by applocker DLL rule policys, when disabling it clearkey addon does not crash and drm content can be played.

Also Applocker eventlogs does not show anything related to this.

Hello

We use our own CA to secure some websites on the internal network. Until version 101.0, the SSL was working correctly. I have updated today to firefox 101 and all our internal websites started giving SSL_ERROR_BAD_CERT_DOMAIN. There are no issues with external CA issued certificates, so I'm assuming it is something related to the way we generate the certificates. Were there any changes done at version 101 which might reject certificates with a valid common name? Is there a way to disable it and revert to version 100 options?

Thank you

Every time Firefox is opened it gives an error message (see image).

I have tried:

  • Deleting and reinstalling.
  • Deleting Firefox folder in //users/xxxxxxx/Library/Application Support & //Library/Caches then uninstalling Firefox.
  • Both above using older Firefox versions.

This issue is happening on all of the Macs in our org. We have no custom configurations. The pkg is installed via FileWave device management. It occurs whether installed through FileWave or manually.

Thanks

Firefox starting extremely slow when custom homepage GPO applied

All our Firefox browsers (version 99.*, Windows 10 Pro or Enterprise) in the company need around 20 seconds to load a web page when first opened. All other browser functions work fluently from the beginning. Also the slowness only happens after opening and not during further use. Which Firefox is refusing to load I can open other tabs and e.g. do a Google search and then the "slowness timer" starts again (independently if the first tab is closed or stays open) and refuses to do anything on that tab. Once the slownedd period is over all tabs are loaded and no further problem occurs. This issue occurs only when the GPO "URL for Home Page" is applied. But this page is reachable and when Firefox is working it loads within milliseconds. For testing I created a new profile and on the first startup the problem already occurs. And all other startups too. When temporarily removing this one GPO entry it immediately works again fluently. It also doesn't matter what I set as home page (company internal website or some random web page); it is always slow once this setting is in place.
