Firefox for Enterprise Isithangami Sokwesekwa

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!

Hello,

Firefox 102.6.0esr (x64) Firefox 108.2.0 (x64)

after implementing the bookmarks (JSON) setting by GPO policy, it turns out that an entry for Bookmarks is created in the registry and not ManagedBookmarks, which causes bookmarks not to appear in the bookmarks bar. When I manually rename a registry entry from Bookmarks to ManagedBookmarks, the bookmarks appear properly. Please let me know if I'm doing something wrong or if there really is a problem reported by me.

Yours sincerely Bart

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.

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.

<enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": "Blocked by your administrator.",
   "installation_mode": "blocked",

Environment:

• Version: 102.3.0esr
• Build ID: 20220912135840
• OS: Windows_NT 10.0 19044

Issue: I had Firefox window 1 opened in virtual desktop 1, then I switched to virtual desktop 2 and open Firefox window 2 there. After using window 2 for some time, I switched back to virtual desktop 1 and found Firefox window 1 was gone. I checked `about:support` page but found no crash report there. I don't know what's going wrong.

Hello, Qualys is detecting Vulnerabilites on our Firefox ESR 91.12 Versions which were patched by MFSA2022-29.

It is showing Vulnerabilities because MFSA2022-30 lists CVE's for ESR 102.X and we are on 91.12.

Is there anywhere I can go to get a list of all Vulnerabilities on 91.X to show our Security team, I believe CVE-2022-36314 and CVE-2022-2505 are not present in 91.12 because they are not listed in https://www.mozilla.org/en-US/security/advisories/mfsa2022-29/ but need evidence

Thank You,

Hello,

As the title mentions, applying a block to all extensions via "*" by utilizing Extension Management GPO will block about:debugging.

Is there a way to simultaneously have all extensions blocked and about:debugging available?

Here's the JSON - { "*": { "installation_mode": "blocked" } }

Appreciate your time and help, - Dom

Hi,

We've GPOs in place for Edge and Chrome that set said browsers on all our Windows endpoints to open downloaded ICA files in Citrix Workspace.

I've imported the firefox.admx and mozilla.admx file along with assocaited .adml files, checked Github, checked through the GPO settings yet cannot figure out how to do the same with Firefox.

Is there a Mozila Firefox for Windows GPO ADMX setting I can use to control the "Firefox>Settings>General>Files and Applications>Applications" section to add "Content type: ica | Action: Use Citrix Workspace"?

Thanking you....

Hello! As you may know, FireFox does not use the Windows Certificate Store by default. Therefore I have to change the "security.enterprise-roots.enabled" in the preferences on each workstation. I have searched and found ways to enforce this change by GPE , but I wonder if there is a way to change firefox preferences, especially the one I've mentioned, via Registry Editor.
