When opening an online Java game Java tries to update the following registry key even though the process does not have permissions to do so and then crashes the browser.
Name = CurrentVersion

Mozilla Firefox as of the 126.96.36.199 release includes an application manifest which prevents registry virtualization on Vista which is how Java was able to successfully write to the registry previously.

The original problem is because plugin fails reading from HKLM\Software\mozilla.org\Mozilla\CurrentVersion on Vista and therefore it could not load.
This is due to new change in FF install engine in which a manifest is used to override virtualization by Vista. Therefore, when FF is installed on vista, it fails to write to HKLM\Software\mozilla.org\Mozilla\CurrentVersion location.
Plugin tries to read this registry to determine what plugin adapter lib to load and therefore the symptom is plugin fails to load on Vista for FF188.8.131.52 and later.
At least no one from deployment team was able to reproduce the crash scenario.
