I don't think updating an application is really comparable to updating an operating system. The OS is vastly more complex.

Nevertheless, Firefox on Linux via package manager definitely requires a restart. Typically I know when Firefox has been updated because I get a window saying "your browser needs to restart".

The restart is not the problem, the time it takes is. (And that it prompts rather aggressively to reboot.)
