I've been tasked with removing Firefox from all Windows workstations in our enterprise environment. Our users don't have local admin, so when they install Firefox, it is installed in the user's profile.

I've just installed Firefox 143.0.1 in my own user profile for testing purposes. However, when I attempt to uninstall, either from Control Panel or by running %localappdata%\Mozilla Firefox\uninstall\helper.exe manually, UAC prompts for elevation, even though I installed without elevating.

I've dug in a bit more, and I found this was an issue five years ago as well:

https://support.mozilla.org/en-US/questions/1286070

According to that post, the issue was resolved, but it seems to have come back.

Any help would be appreciated.

I have several users that are running Firefox 137. When attempting to update, they get the message that the organization has blocked updates. There is nothing I can see that we have done. Attempted to update registry and .json file. I cannot find where the block is coming from. Do I need to delete and reinstall?

I look after about 20 PCs. All Windows 10. All were running Firefox ESR ranging from 115 - 128. As I get time I update each to the latest 128.x. Using group policies I've disabled all update settings.

However, on two of the PCs, they have updated to v139.0.1. Both of the users swear they did not manually do any update. I can't figure out how they got downgraded to the retail channel.

So my question is, since 128 < 139 how can I get them back on to the ESR channel, without loosing history, bookmarks, passwords and saved logins? I gather FF's installer will detect 128 as an older version and throw an error?

ESR -> Retail to me is a downgrade. So is it possible then to upgrade back to 128.11.x?

Each PC is refreshed annually and the only backup of the profile folder I have is from the last refresh, which in most cases in 8-9 months old.

Is there any way to find out why the downgrade happened when group policy forbids it, and the user did not manually download and install the latest version?

When these downgrades happen they break things. For example, when one PC was downgraded to retail his outlook.com email no longer works. If he uses his laptop which is on 128.11.0 it works fine.

Dear Mozilla Firefox Team,

I hope this message finds you well.

We manage a network of workstations that frequently utilize the Mozilla Firefox browser. Recently, we have encountered a situation where many of our systems are showing vulnerabilities due to pending browser updates. The updates are being installed successfully; however, users often neglect to restart the browser, which is crucial for completing the update process and ensuring security.

To address this, we would like to inquire if there is an existing Group Policy that can be configured to automatically notify users when they need to restart their Firefox browser to apply the latest updates. Such a feature would greatly assist us in maintaining the security integrity of our workstations and ensuring that users are made aware of the importance of restarting their browsers when prompted.

If this functionality is not currently available, we would appreciate any insights on potential workarounds or future plans to incorporate such a feature.

Thank you for your attention to this matter. We look forward to your response.

Hi. On an Active Directory, we deploy Firefox (normal or ESR). It's OK. When we deactivate the link of the GPO, it's supposed to uninstall. But it doesn't (even if we delete the GPO, specifying to uninstall at once).

The gpresult command on each computer doesn't show the GPO anymore, but Firefox is still installed.

( FYI, we used to do that with FrontMotion Community Edition, and it was always working (instal and uninstal). We even just tried the "last" (but old) ESR edition present on the FrontMotion site (CEESR-102), and it works. But FM CE version has stopped being developped. )

So, any idea about why the official Mozilla Firefox version (normal or ESR) doesn't uninstall?

Thanks by advance.

We use Firefox ESR in our environment today, Is it possible to have a policy that would display "update required" message to end-users, or have it automatically update without users opening the browsers.

Debian 12 Linux on Dell laptop. Current "updated version" Firefox ESR 128.4.0esr (64bit) I received an update notice for Firefox ESR this morning. After running the Update, I lost the status bar. How can I get it back?

Le 05 novembre 2024 Bonjour, Je ne parviens pas à faire la mise à jour FireFox. J'utilise un MAC OS X version 10.9.5 Processeur 2,7GHz Intel Core 15 Mémoire 8 Go 1600 MH DDR3 MERCI de bien vouloir me répondre en Français. Bonne journée. Cordialement.

No matter which option I choose, I keep getting a message that tells me Firefox cannot be updated. The Oesr version wont update either. It tells me to update to 115.17 Oesr and when I click on update I keep getting this error.

Hi,

Looking to upgrade our org to ESR 128.2.0 due to compatibility issues - most notably, embedded PDFs not loading due to Promise.withResolvers() not being implemented on versions prior to 121.

Curious to know if there are any issues or concerns with upgrading manually/pushing this version out - would like to ensure we don't cause further issues in attempting to resolve one.
