Right after I posted my previous comment I googled and found a solution for the folder view switching. There is an extension available that provides it now. It's called "Folder Pane View Switcher" and it works just fine. I provide a URL below but it's not needed if you use the thunderbird add-on manager to download and install it.

It is very disappointing to run a regular (bugfix) update with this result!!! Does anybody at the Ubuntu Team feel responsible? Thank you for your help.
