The last time I used PaleMoon it had other issues (although there was
a fork of it that even worked with Windows XP).  With its new display
engine, Firefox has broken most of my old viewing habits.  By now I
got too tired of adapting.

That's why I prefer multiline tabs.  Hscrolling always has the
potential problem that one considers things scrolled off as things
that are not present.
