Mozilla Maintenance Service

What is Mozilla Maintenance Service?

Firefox now installs an optional service called the Mozilla Maintenance Service. This service allows Firefox to install updates without requiring you to click yes in the Windows User Account Control (UAC) dialog. Once Firefox has downloaded an update, the Mozilla Maintenance Service gets permission from Windows to allow the update to be applied without requiring you to click yes in the Windows User Account Control (UAC) dialog. Until that time, the service doesn't run so it doesn't use any computer resources. And once the update process begins, the service quits. Before this feature, when a user installs into the default Program Files directory, updates cannot be applied without us first prompting the user for elevated permissions with a User Account Control (UAC) dialog.

Now that this feature is implemented, Firefox uses a service to execute updates so that UAC prompts are not displayed. The service is run "on demand" and will remain stopped until it is needed. When the service is needed, it will be started again for the period of the update. If there are any problems updating through ...  Read more

My Rootkit scan says it is a harmful rootkit. Just wondering why this is.

Depending on the usage environment of the computer, you should remove it as it has some serious vulnerabilities which allow MalWare (which can even run off a website, without needing to be locally installed) to perform operations at the same permission level as the user. If you are using comprehensive Antivirus, Antispyware & Anti Malware detection (e.g. a typical "Internet Security Package") then it should pose no significant risk. If not, then I would advise against keeping it.
