After our first release was rejected, the second also, we were busy with other things. After New Year we started to work in it again and fixed the issued stopping the submission process.
We resubmitted again and hope for the best this time. We are on position 46.
Even we were using much stronger sanitizing rules, the Mozilla folks were not comfortable with this. Hence, we are applying their preferred way and on top ours.
We updated all libraries and ran into the problem that openpgp.js changed their API. Hence we are busy to adjust our code. This is not a tiny change and we improve our code while migrating to the new API.
