SUMMARY
When KDE window decorations are customised to appear on both ends of the
titlebar, Firefox 142 crashes on launch.
STEPS TO REPRODUCE
1. Go to settings -> colours and themes -> window decorations -> configure
titlebar buttons.
2. Ensure close, minimise, and maximise buttons appear on both ends (left and
right) of the titlebar. Save changes.
3. Attempt to launch Firefox 142.
OBSERVED RESULT
Firefox immediately crashes. Running in terminal produces an error:
/usr/include/c++/15/array:210: constexpr std::array<_Tp, _Nm>::value_type&
std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = HeaderBarButtonType;
long unsigned int _Nm = 3; reference = HeaderBarButtonType&; size_type = long
unsigned int]: Assertion '__n < this->size()' failed.
EXPECTED RESULT
Firefox launches normally
