We are deploying Firefox ESR using Ivanti and have reached a point were were need to start cleaning up rogue installs of Firefox that we are not managing. Has anyone deployed ESR over a local install of Firefox. Does the end user end up with two version of Firefox install or does the ESR version write over the previously installed version? Does the end user lose their bookmarks and history? I'm just curious as too what others have experienced so I can notify my first test group on what they can expect.

The ESR will overwrite the existing version ( we use the same paths)

The main problem you'll run into is that we have downgrade protection that prevents you from using ESR 91 with a later profile.

You can override this by setting the environment variable MOZ_ALLOW_DOWNGRADE or launching Firefox the first time with --allow-downgrade
