about:settings seems to be inconsistant as to how files are handled according to type
In about:preferences, in the ⚙ General tab, Firefox is set to handle the content of type "Zip archive" with the action "Use Archive Manager (default)".
To the question of what Firefox should do with other files, the set answer is "Ask whether to open or save files".
When I click on a link to a zip archive, said application indeed launches, no question asked, which is what I expect. However, the zip file is also saved in ~/Downloads which is, of course, where the files go when the corresponding action is set to "Save file".
In a similar vein, MP3 files are supposed to launch VLC but play in Firefox (which is also fine, just not what's set in about:preferences). M3U files do lauch VLC as set but are saved in ~/Downloads. PDF files are opened in Firefox, as the settings say they should.
Those inconsistancies seem to have started only a couple of weeks ago.
The nuisance is indeed moderate but still somewhat disconcerting.
The operating system is Debian 11, the desktop environment is XFCE4. The version of Firefox is 102.7.0esr (64-bit).
Is there something I misunderstood ? Some settings that I overlook ? A page in TFM that I didn't read ? Or is this random behavior something that comes with the territory ?

Try making this preference in about:config true : browser.download.start_downloads_in_tmp_dir That restores the previous situation where files you want to open but not download are placed in your temp directory.

Note that support for browser.download.start_downloads_in_tmp_dir got added with Firefox 102, so this should work for you.
Terry's and cor-el's replies do restore the expected behaviour. Nevertheless, MP3s still open in Firefox instead of launching in VLC as set.
Again, not a big deal, it's just that the back-office and the UI do not agree.
It does seem to be a mess. You could try "Always ask" instead of specifying an application.
You can set this pref to false on the about:config page to prevent Firefox from playing media files you open in a tab via the HTML5 media player.
- about:config => media.play-stand-alone = false
