Yes, would be much more clear. Perhaps softwares usually don't need a pc restart as they don't need that their functions are shut down temporarily for being updated, for example a software that monitor or change Windows options, an antivirus, a driver or simply Windows updates can require a pc restart becauce they are still in use (including in background) for the correct system operation and of course can't be updated if they are still active. So, to update Firefox you just have to restart it, it will close and the update will be applied, then Firefox will open.
