      I suppose this is the difference between "normal upgrade" and 
"smart upgrade" in Synaptic. 'smart' means it is allowed to install new 
packages to satisfy dependencies, like "dist-upgrade".


     When you click upgrade-all in Synaptic, it will use the method you 
have selected as default (normal-upgrade, in my case), but if you 
explicitely ask to upgrade a package, then it performs a smart-upgrade 
but only to satisfy the dependencies of this very selected package.


     I would be afraid to run a dist-upgrade on the whole distro every 
month or so.


     Concerning your example, I retained Iceweasel for severall months 
because the only thing I expected from FF-ESR was more bloat. I 
eventually let it "upgrade"  to FF-ESR after a few months because it 
seemed to get into trouble.
