error when converting some pages

[TomasEkeli]

getting an error that says global.crypto.subtle is undefined on some pages

e.g. http://distributedweb.care/posts/who-owns-the-stars/

Apparently some cryptographic functions are not available on insecure pages, e.g. those without HTTPS 🔒. I never encountered that.

I wrote a fix that avoids using those (here non essential) functions when not available. But Mozilla's extension signing times out, so I currently can't publish it 🙄

Alternative for now: use HTTPS (which the example page supports)

A couple attempts later, and the CI build works again. The update is in the DEV channel now.
