Firefox for Enterprise Support Forum

I am installing Firefox via microsoft endpoint, and deploying multi account containers with the OMA-URI policy for extensions. (this blog page is super helpful! https://securitygeneralist.blogspot.com/2019/08/auto-installing-extensions-on-firefox.html )

The extension by default has containers for Personal, Work, Banking, Shopping.

Is there a way to automatically remove that default container list as part of the install?

Even better, is there a way to create a different default containers list through Endpoint?

Thanks

We have around 1000 Firefox installations on our government organization, all installed via the Firefox MSI installer. Unfortunately, we came late to realize that the Firefox ESR would be a much more suitable product, compared to the normal Firefox branch.

Now, some years ago we would simply mass uninstall the normal Firefox and mass install the (latest) ESR version and all would be well. Problem is that we have to keep existing profiles (including passwords/bookmarks etc), something that is not supported in the latest Firefox builds.

Can anyone offer some advice/"hacks" to accomplish this? Note that whatever we'll do, we'll have to do it automatically, we lack the man-power to do this manually on a system by system basis...

Thanks in advance for any information provided.

Has anything changed in Mozilla Maintenance Service in regards to security required for the logged on user in order for Mozilla updates to be installed? We do not allow our users local admin rights, but instead they have an application where they can request admin rights when needed, and with the release of Firefox 89, we are seeing peoples Mozilla products disappear. In the logs it looks like an update is being made, and once the old version has been deleted, the new version fails to install.
