I do this kind of thing all the time with the Lancelot launcher (I'm still rocking a KDE4/Plasma4 desktop); sadly it appears no one migrated that launcher to KF5.

Thank you for the reply. In fact, here is ~/.local/share/applications/chromium-browser.desktop that the application launcher currently uses:
Comment[en_IE]=Browse the World Wide Web
Comment=Browse the World Wide Web
Comment[en_US]=Browse the World Wide Web
I have also tried
Exec=CHROMIUM_USER_FLAGS="--disable-font-subpixel-positioning" chromium %u
which of course failed too.
One thing that works for now is putting
directly into /usr/bin/chromium (sorry, this is a cross-post from opensuse ml, so I forgot to specify that it's a shell script that, besides other work, appends all flags found in CHROMIUM_USER_FLAGS to vendor-specific (in this case opensuse) launch flags).
Even though it works, this solution is not scalable.
I am probably missing something crucial about .desktop files, application launcher or bash scripts.

Yep, AFAIK this flag is the only way. In fact, it's a bug abuse.

Unfortunately, not on my machine: chromium starts faster, loads page elements faster, has better plugin support (after FF killed XUL, developers neglect testing and porting their plugins for FF, which leads to all sorts of unusable plugins), does not have an annoying window resizing bug (when FF is in fullscreen and is closed, it reopens in fullscreen, but the content frame is rendered only on some small piece of the screen, which is fixed by manually toggling "restore" button). Furthermore, FF (and Thunderbird) developers do all sorts of mental gymnastics to not do something that users highly request, but what the developers feel like working on (see e.g. , and numerous other 10+yo bug reports), even if a feature is essential. Added to multiple recent "oopsies", I have serious trust issues with the direction FF is moving.
The only thing that chromium does slower is when pressing the "sandwich" button it takes bizarre ~5 seconds for the menu to appear.
