Hi Martin, symlinks is indeed the issue. Unfortunately and contrary to what was stated in that bug report, an absolute symlink doesn't work either.

For the time being you can work around the issue either by using firefox-esr instead of firefox (65) which is why I myself had not yet noticed this issue, it was working perfectly fine for me.

If you cannot run firefox-esr and must run firefox 65, you can also work around the issue by running:

$ sudo rm /usr/share/webext/umatrix/lib/punycode.js
$ sudo cp /usr/share/javascript/punycode/punycode.js /usr/share/webext/umatrix/lib/punycode.js

Since it works perfectly fine in firefox-esr I assume it's a regression and that the firefox Debian maintainer can hopefully get a fix out soon.
