What happens when the OS that is running the browser fails to update because /boot has run out of room for a new Linux kernel (this happened to me the other week)?
What happens when the browser update fails because the package database got corrupted?
What happens when a lock file stop the whole system updating because of a previous iffy update?
You are going to need to drop to a terminal and fix that issue or reinstall the whole OS.
Either way you are going to need to know something about how the machine works.
