A recent pdf.js update: https://hg.mozilla.org/mozilla-central/rev/af98d67916ad removed the MPL 2 headers added in: https://hg.mozilla.org/mozilla-central/rev/74a06c56da4e Could this please be fixed? It might also be worth investigating why the update procedure for pdf.js does not seem to involve merging with the current code, but rather overwriting it... Gerv

Gerv, PDF Viewer component portion is licensed under Apache license v2 and .properties files are part of it. Shall those files be MPL2? > It might also be worth investigating why the update procedure for pdf.js does not seem to involve merging with the current code, but rather overwriting it... We are tracking this issue at https://github.com/mozilla/pdf.js/issues/2275

Yury: good point :-) If these files are part of pdf.js itself (and not part of Mozilla's integration of pdf.js) then yes, they need Apache headers instead. Gerv

These files are used in our web based viewer as well, so I think the apache header makes more sense. We'll fix upstream.

Fixed by bug 810107.
