Firemin Server is a small yet powerful tool for minimizing the impact multiple browser sessions has on a Windows Server’s resources. Specifically, it will minimize memory usage of multiple browser sessions on for example a terminal server. Consequently, you can allow your users to use Firefox without worrying about precious server memory being abused. Therefore this is especially useful on low memory servers.

Firemin Server has a small resource footprint and easy to use. That said, It is the only server grade program of its kind and we are swimming in unfamiliar waters. So, test it and let us know if you experience any issues or have some suggestions. Like Firemin, it was developed to optimize Firefox’s memory usage, but can be used to optimize the memory usage of any stubborn program.

Server Software

Firemin server is developed to run in a Windows Server environment. It does not optimize the core process of the selected program, instead, it cycles through all running processes and optimize each. Using this method ensures that each process regardless of the owner is optimized. However, this method is not sufficient for a desktop computer, this is why we recommend using Firemin Server for a Windows Server environment and Firemin for a desktop environment.
