Only DeltaH uses Builder. Does the bug also exist there?
The bug seems to be also present in deltah.
I downloaded xulrunner-1.9_1.9.0.19+nobinonly.orig.tar.gz at
http://archive.gnewsense.org/gnewsense/pool/main/x/xulrunner-1.9/. In
'mozilla' directory of this uncompressed file, I found:
$ grep * -e "pfs.mozilla" -r -n -i
toolkit/locales/en-US/chrome/global-region/region.properties:8:more_plugins_url=https://pfs.mozilla.org/plugins/
