Hello,

I am managing Firefox for a very large organization. We have several extension that we deploy using registry keys and we don't allow users to install additional addons. However, since version 102.3 I noticed some extensions that are present on the machine as .xpi files, but should not install unless a specific application is also present, are also being activated. They are enabled in the add-on manager, the information is present in the "extensions.json" and "extension-preferences.json" files. This should not happen. Is there any way to prevent the activation of these files?

Thank you!

I try to disable the transition to fullscreen by following the steps. But after restart the Firefox ESR (waterfox), the rule don't apply. The rule:

/* Minimize fullscreen transition time */
#navigator-toolbox[fullscreenShouldAnimate] {
    transition: 0ms !important;
}

Hello,

I'm trying to deploy Firefox with several languages.

I followed the guide on [https://support.mozilla.org/en-US/kb/deploying-firefox-language-packs].

Everything work fine until I set up ExtensionSettings policy. This policy hide and block languages menu.

After scratching my head for a while, I finally figured out how to do it. I would to like to know if an easier way to whitelist all locales and dictionaries. I would like to only control the extensions.

I am using Firefox ESR 102.2.0 version which I updated yesterday. Now when I try to login to my account on "https://myaccount.hdfclife.com/login", the captcha is covered and I can not read it. See the attached file.

It was working fine in the previous esr release 102.1.0. I have tested it with a new profile and captcha is visible in 102.2.0 version.

My query is about the cause of this issue and how can I fix it. I have checked and found that this issue does not appear on other websites. If there is an issue with the profile it should be with other websites which is not the case.

Please help

There is a certificate for an internal website that FireFox is saying is not valid/secure and it makes you add an exception. However, if you use IE, Edge or Chrome it loads fine with the valid CA Certificate. I've cleared all data (cache/etc...) and it hasn't fixed it. Hopefully someone has a fix for this?

Getting "SEC_ERROR_UNKNOWN_ISSUER" for the certificate and its saying:

   Peer’s Certificate issuer is not recognized.
   HTTP Strict Transport Security: false
   HTTP Public Key Pinning: false

Hi,

I got an issue that bookmarks are saved in the library, but this doesn't reflect on the Bookmark toolbar.

I have already removed the entire profile, did a reinstall .. nothing seems to reset it. When I perform a backup, the entries are also in the backup json.

I hope somebody can help, this started happening recently it seems.

Thanks in advance!

Firefox for Enterprise -> Firefox

Hi,

Is there any possibility to provide funding to prioritize the resolution of certain defects in Firefox? We do not have the in-house knowledge to contribute the fixes ourselves but would be interested in providing funding to have them resolved faster. Is there any way to achieve that through Mozilla foundation or could please recommend some other solution?

Best regards Josef

As Chromium has been announcing, version 98 removed support for TLS 1.0/1.1. I know Mozilla has extended support for TLS 1.0/1.1 due to the Covid-19 pandemic. Other browsers did the same.

I’m curious if there is an official statement on a target end date for TLS 1.0/1.1 in Firefox Extended Support release. While the warnings show up, “Connection not secure. This page uses weak encryption”, can we expect Firefox ESR to stop this displaying websites using TLS 1.0/1.1?

What I’m hoping to avoid is a surprise. Thank you for your time, and I really do appreciate this community!

We realized that our Firefox ESR 91.4.1 (installed on couple of hundreds of PCs) tries to connect to the IP 34.107.221.82 which is marked as high risk. How is it possible? What exactly wants Firefox to do with this IP.

It is strange that connection to this IP goes directly and be blocked on our corporate firewall. Why does it go directly even if proxy is enabled and works. ?

Kind regards Vladimir

I just created a policies.json file in the appropriate distribution folder with ONE policiy, then restarted the browser, and now the browser shows: The browser is managed by your organisation. ("Der Browser wird durch Ihre Organisation verwaltet." in German.)

Now the question occured to me: Has this any effect on the changes I made before manually in the about:config section, or in the settings UI, other than the one change by the one policy I put in the policies.json?

Firefox 91.3.0esr (64-Bit)

Hello, I ve tried to block file:///c:/ in Firefox Quantum release 60.4.0esr(32-bit) by the above .json with no results. I ve also tried to block it in a newer release and it was fine (78.15.0esr (32-bit)). Is anything i can do to block it in this particular version i m using(60.4.0esr(32-bit))?

Thank you

Hello,

we have some trouble in our Enterprise Environment with tls 1.3 and 0rtt data. The integrated google search and other websites doesnt work as they should (Pages doesnt load and stay white).

So we want to turn of "security.tls.enable_0rtt_data" with Group Policy. But i cannot find a switch for this setting.

When i try to set security.tls.enable_0rtt_data with Preferences in GPO it doesnt work (old Preferences is empty) { "security.tls.enable_0rtt_data": { "Value": false, "Status": "locked" } }

With Preferences i am able to configure security.tls.hello_downgrade_check, but not security.tls.enable_0rtt_data

The only workaround would be to disable tls 1.3 completely and use tls 1.2. (security.tls.version.max = 3) Is there a solution for this?

Regards, Michael

Hello world,

This problem is sticking for a year now. We even switched to ESR thinking it will fixed the problem but to no avail. After a bunch of test, I've finally decided to post and ask for help. Tests have been done on macos 11.6 fresh vanilla install, no encryption (no filevault, I hate it), and Firefox 91.1.0esr (64 bits), but problem is the same since version 75 + (no problem seen on windows or linux) If I don't use Profiles Manager, at each launch of Firefox a new profile is created with no import from former profiles. If I do use Profiles Manager, I can keep on choosing my default profile, and no new ones are created, BUT new install is added to install.ini and profiles.ini. All tests have been done with the exact same firefox (i mean, application is the same and correctly installed in the /Applications of macos).

Here is the profiles.ini

[Install5A291CFD23D97DBF] Default=Profiles/ucaeqkrb.default-esr Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/ucaeqkrb.default-esr Default=1

[General] StartWithLastProfile=0 Version=1

[InstallF5B6C4E8673B7987] Default=Profiles/ucaeqkrb.default-esr Locked=1

[Install7F9608401B386673] Default=Profiles/ucaeqkrb.default-esr Locked=1

And the installs.ini

[5A291CFD23D97DBF] Default=Profiles/ucaeqkrb.default-esr Locked=1

[F5B6C4E8673B7987] Default=Profiles/ucaeqkrb.default-esr Locked=1

[7F9608401B386673] Default=Profiles/ucaeqkrb.default-esr Locked=1

As you can see each launch of Firefox created a new hash of installation (even if same it's always the same firefox version). As long as I choose my default profile in profiles manager, I can keep it. If I switch to default comportment, I will get a new profile at each launch (as it see en new install hash) and it will not import former profiles (even if it's from the same or an older version).

So I'm wandering, why Firefox keeps on adding a news install hash on each launch, and/or how can I prevent it from doing it.
