[Pkg-mozext-maintainers] Bug#919557: webext-umatrix: garbled display of toolbar menu in Firefox 64.0-1

[Martin Steigerwald]

Package: webext-umatrix
Version: 1.3.14+dfsg-2
Severity: important

Dear Ximin,

I just installed webext-umatrix and found that its control panel does not
show up correctly in Firefox. I attach a screenshot.

Some chars are missing, as if a font could not be loaded. Also the matrix
of what is allowed and forbidden is not displayed at all for any webpage I
have tried. The bug looks similar to

webext-ublock-origin: Missing icons in the toolbar menu
https://bugs.debian.org/916431

where the issue was Firefox did not follow a relative symlink to the
necessary font file. Maybe something similar is the culprit here?

Thanks,
Martin
