Hi,

I deployed the last Firefox ESR update and I just found about this new feature : https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu

So files are now downloaded and users are no longer prompted for what to do. My question is can we change this to "Ask whether to open or save files" using policies.json?

Kind regards,

McB

I have a need to use regular browser (not kiosk), but disable the "open downloads folder" once a file has been downloaded. This is opening a file manager (thunar or alike) which then allows the user to browse the filesystem and open a terminal emulator from /usr/bin.

Using the policies, I am able to prompt for downloads, or select a download location, however I have been unable to completely stop the user from opening the download folder which opens a file browser.

Is there any way I can select policies or profile options for disabling the option for opening download folder?

From my point of view, the setting " What should Firefox do with other files?" has been added in the current ESR version.

"What should Firefox do with other files?" ("Wie soll Firefox mit anderen Dateien verfahren?") . "Save files" ("Dateien speichern") . "Ask whether to open or save files" ("Fragen, ob Dateien geöffnet oder gespeichert werden sollen")


How can I control/change this setting using mozilla.cfg?


By the way:

// What should Firefox do with other files? - Wie soll Firefox mit anderen Dateien verfahren? lockPref("applications-ask-before-handling", false);

// What should Firefox do with other files? - Wie soll Firefox mit anderen Dateien verfahren? lockPref("applications-ask-before-handling", true);

works detectably via about:config but does not change the setting for "What should Firefox do with other files?".

Hi, Background: a few months ago I had to redeploy the CA for a network I manage. I was able to do so and publish the new intermediate CA's cert via Active Directory. Since then, I've updated certs on webhosts with certs from the new CA. Whenever a user uses FF (version 91.12.0) to browse to a site with the newly signed cert, I get an error stating "sec_error_ocsp_old". I've been able to temporarily advise users to disable OCSP Validation in FF security settings, but I'd REALLY like to fix this.

Other browsers (Edge, Chrome, Opera) all load the sites without issue.

Using this the below article, I double checked the time settings on the CA, Webserver, and clients: https://support.mozilla.org/en-US/kb/troubleshoot-time-errors-secure-websites

All the machines/VMs in question show the same time source, time, time zone, and sync interval.

I'm at a loss for what is happening. Any help would be greatly appreciated.

Note: I need my website to fit into browser properly at 100%(default) zoom itself for the purpose of automation because changing zoom level via selenium automation to press ctrl and minus 3 times causes unexpected behavior like even though value is filled in a textbox, it doesn't get sent in the API request payload.

Hi,

I've been tasked to make some changes to the way users deal with logins and passwords in the office. So, in short, one of the issues is this: is there ANY way to disable (I'd say "hide" is more accurate) the about:logins page on Firefox?

  • pref.privacy.disable_button.view_passwords (with a lock pref) in autoconfig only disables the "View saved logins" button in Settings.

As for policies:

  • a few policies for blocking about: pages do exist - BlockAboutAddons/Config/Profiles/Support, but can't find one, say, "BlockAboutLogins" or something like that.
  • PasswordManagerEnabled set to false disables the password manager completely, including about:logins, password autofill is disabled as well - not what I need.
  • WebsiteFilter, as expected, doesn't treat about: as a protocol, so it can't be done there either.


Any help is appreciated. Thanks in advance!

I am deploying Mozilla Firefox using Intune. The application is deployed no problem but there is always the error in Intune portal. I was told that Mozilla Firefox has custom return codes to indicate post-installation behavior. That is why though the application itself is installed and works properly on the device, Intune portal does not know the status of the installation and gives the error. This error causes a lot of issues to the further application management. Dose any one knows what those codes are? Or maybe can point into the correct direction on how to get them. Thank you.

Hi, I need to deploy the Firefox ESR version to 10 different languages using language packs, but I see from this documentation that one of the criteria to use Background auto-update is to don't use language packs.

app.update.langpack.enabled must be false, or otherwise there must be no langpacks installed. Background tasks cannot update addons such as langpacks, because they are installed into a profile, and langpacks that are not precisely matched with the version of Firefox that is installed can cause YSOD failures (see bug 1647443), so background updating in the presence of langpacks is too risky.

Is this documentation still valid for branch 102 or now is possible to use it? If not, will it be possible in a future release to use auto-update with language packs?

Thanks

When using Firefox in my enterprise environment the Internet path goes through HTTPS decryption, which works fine with Firefox once the enterprise root CA cert is installed. But, I've gotten reports of problems with updates.

Hello,

Applying Preferences & Extension Management GPO's will bug certain GUI settings. The three examples I have are HTTPS-Only Mode & Forms and Autofill within about:preferences, and Enable USB Devices within about:debugging.

When HTTPS-Only Mode is set to "Don't Enable HTTPS-Only Mode" and locked via Preferences GPO, Users can continue to toggle between the settings. Forms and Autofill settings will not populate within about:preferences if address and credit card formfill values are false and locked via Preferences GPO. However, when the same GPO is deployed from Active Directory, Forms and Autofill settings will populate with address available for User toggle. Key, the values within about:config reflect what is set via GPO, and do not change among toggle or User intervention.

When locking down Enable USB Devices within about:debugging by blocking the extension install via Extension Management GPO, Users can continue to toggle the button after the policy applied. Although, just as previously mentioned, the extension does not get installed and seems the policy intervenes.

My questions being, are these simply GUI bugs since the values respect group policy? Are there other methods to lock down these settings?

I understand this is quite a bit of information and appreciate your help and time!

Preferences JSON - { "extensions.formautofill.creditCards.available": {

   "Value": false,

I am an administrator at a university and we use Blackboard and Zoom as a couple of the tools at our university. We install Firefox on all of our PCs across campus. After a recent update, when our instructors try to launch Zoom using the integration setup in Blackboard, the meeting fails to launch. We have found that disabling Enhanced Protection fixes this issue. Is there a way to add this exception to an install file that can be sent across many PCs on our campus? We have hundreds of PCs and going from one to another to install this exception would not be practical.

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.
