The homepage for the scowl package says at http://wordlist.aspell.net/

SCOWL (...) is a database of information on English words (...) The database primary contains information on (...) (basic) part-of-speech and (...)

And at http://wordlist.aspell.net/agid-readme/

A typical entry will look like
WORD V: WORDed, WORed 2, WORD {EXPL} | WORDing, WORing 2 | WORDs
<pos> is V for verb, N for noun, or A or adjective or adverb.

This is exactly what I'm looking for. However, the mentioned file infl.txt doesn't seem to be part of the package? And doesn't seem to be part of any other package?

Which package does contain this file and/or is there any other package which contains a file with similar contents? (Doesn't matter which package, scowl is only the first one, I found.)

The Software Updater update-manager pops up and shows security updates for Firefox, for example. Naturally, I will click on "Install Now" to continue.

However, what happens if I still have Firefox running when I do this? Will it still update Firefox? Will the update be skipped and just pop up next time, again? Will the update force Firefox to close and maybe crash? Will it only partially update the software and possibly break my Firefox installation?

In the "Software & Updates" preferences, there is an option to automatically download and install security updates:

It seems like this is a very reasonable option. I won't have to bother with updates for two weeks and everything will be done automatically in the background. However, I wonder if it is safe, too? What if I logout or reboot at a wrong time during the installation, because I don't even know there is an installation running?

There are many instructions on how to enable autologin on various Ubuntu-based distros. However, I couldn't find a solution explicitly for Lubuntu 16.04 LTS with LightDM.
