bifulushi support, maintainability, longer term availbility in Firefox

It looks like containerize, that bifulushi is forked from is likely going unmaintained. Unfortunately bifulushi isn't a one for one substitute. That lead to a few questions about this project

• do you think that long term bifulushi could get to a stage where it could go back into Mozilla store - e.g. when sandboxing becomes available?
• if not, would it be possible to build two versions, one with the features relying on eval disabled so that it could be included in the store?

I note there haven't been that many PRs merged in the last couple of months. Is this project looking for people to help?
