Firefox GPO to add certificate exception

Hello. I know how to define a server certificate exception to avoid browser warnings in case of certificate issue with a website (see attachment). However, I'd like to apply that exception for all users with access to my machine using a GPO (for user or local machine). This is also a requirement in my work where many users run Firefox from a server and the face browser warnings all the time (related to self-signed certificates) so it would be great to apply an exception for all users through a GPO specifying the self-signed certificate warning we want Firefox to ignore. Thanks.

Force-Pinning Extension doesn't Appear to Work (GPO in Microsoft AD)

I am having the same issue as this other user here: https://www.reddit.com/r/sysadmin/comments/17wvuwh/help_pinning_extension_in_firefox_with_gpo/

Preliminaries -- Initially (before trying to force-pin), I had these GPOs enabled:

Extensions to Install -> https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

Prevent extensions from being disabled or removed ->

(Those GPOs above all work.)

What I'm trying to do: Force-pin Bitwarden.

I believe I've followed the documentation correctly (except for not including a "*" case): https://mozilla.github.io/policy-templates/#extensionsettings

I've enabled this GPO with this value:

Extension Management ->

{

 "{446900e4-71c2-419f-a6a7-df9c091e268b}": {
   "default_area": "navbar"
 }

}

After running various "GPUpdate"s and whatnot, the option to uncheck "Pin to toolbar" is still available to click.

I've verified in "about:policies#active" that the JSON item appears next to "ExtensionSettings" and that there are no errors listed in the "Errors" tab.

I've also verified that it appears in the correct location in the Registry.

Since another user had the same issue (Reddit link above), I figured it'd be a good idea to check in with y'all to see if we are missing something.

Thanks for your help!

Firewall changes required after updating to Firefox v132

After updating to v132 I have noticed a significant increase in the load times for some websites that our users connect to. Using v131.0.3 I usually see < 1 second load times for the two websites I am monitoring but after upgrading to v132 it is consistently taking 18-19 seconds for the same page. I have tried uninstalling v132 and reverting to v131 and it immediately goes back to the much faster load times. I have also tried installing various v133 releases and I see the same performance issue as for v132.

The environment I am working in is behind a network firewall with relatively restrictive internet access and I am wondering whether there are sites that Firefox is trying to connect to for the new anti-tracking or suspicious activity features (or anything else) that are being blocked and are therefore causing timeouts and retries that are bumping the total load time up.

Can anyone think of anything else I could check or change?

Firefox version

   128.2.0esr (64-bit)

Operating system

   Windows 10/Windows11 23H2 Septembre patch

Hello everyone,


maybe you can tell me/explain what the problem could be.

In our company we had Firefox version 115.14.0esr (64-bit) and then we updated to 128.2.0esr (64-bit).

Since version 128.2 ESR we have experienced problems in Firefox when trying to access DNN+ pages (with login). https://www.dnn.de/sport/regional/dresdner-sc-denkt-ueber-uebernahme-der-margon-arena-nach-C3IC74MZ6FE43AKGCZJSKUXA3I.html

In Firefox the content is cut off, in Edge it is displayed normally.

With Edge and Firefox 115.14.0esr the page is displayed normally. No AdBlock installed.

In developer mode I see the errors in the versions, so it shouldn't be that.

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://gum.criteo.com/sid/json?origi...AAAAAAAA&gdpr=1. (Reason: CORS request failed). Status code: (null).

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://id5-sync.com/api/config/prebid. (Reason: CORS request failed). Status code: (null).

Any ideas? Thank you very much! :)
