Re: Ubuntu Updater: What Are All These Updates For? Which Ones Should I Install?
Bug fixes and security patches, mostly. If you have any PPAs added to your system, you'll also get updates from them which may include new features. Also, on Ubuntu you typically get new versions of your web browser(s) too, which may also contain new features.

How do I know which ones I ought to allow to be installed?
A program such as Firefox is not just one single self-contained entity. There are other support libraries, also packaged up, that constitute part of Firefox. They might not even have the word "firefox" in their name (for instance, "xulrunner" is a package associated with Firefox). Some will be obviously part of another program ("firefox-global-menu-support"). If you get a new version of Firefox, you also get new versions of the other packages automatically. Don't worry if you don't recognise the names, they are packages that are already installed and already serve a function on your system. The system is just offering to install the newer versions.
I don't see any explanation of what they are included with the notice. I don't recognize any of the updates from their titles.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
