Bug ID: 399529
Summary: Firefox doesn't use mscorefonts properly after KDE
Neon 18.04 upgrade
Product: neon
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal

simple example html file
SUMMARY
KDE Neon upgraded to 18.04 seems to have broken something with how Firefox uses
ttf-mscorefonts, and it will no longer use Arial, Times New Roman, etc. Instead
it defaults back to the Noto font family.
Note that this is NOT about mapping "sans-serif"->Arial as a default font. When
the font is explicitly set to Arial, with no fallbacks, it is not used.
I've attached a sample html file below, it just shows examples of
font-family:arial, etc.:
<p style="font-family: arial">This should be Arial</p>
STEPS TO REPRODUCE
1. With a fresh install of KDE Neon 18.04 (optional?)
2. Open the test file with Firefox.
3. right click the text -> inspect element. In the inspector at the bottom
right, choose 'computed' to see the font family is supposed to be Arial, etc.
Choose 'Fonts' to see that Firefox chose 'Noto Serif'
4. run 'sudo apt-get install ttf-mscorefonts-installer' and follow prompts to
install.
5. reboot and/or reopen firefox with the same file. Re-inspect the same element
and see the effective font.
OBSERVED RESULT
Font is still shown as the Noto family.
EXPECTED RESULT
Font should be Arial (or Verdana, Times New Roman, etc.)
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.1
Firefox Version: 62.0.3
KDE Neon user edition neon-useredition-20181004-1723-amd64.iso
ADDITIONAL INFORMATION
I performed the steps above with a fresh KDE Neon ISO in a VM, and again with
an Ubuntu 18.04.1 ISO. Installing mscorefonts works in Ubuntu, so it appears to
be something specific to KDE/KDE Neon.
