For a moment, I got excited for this. It did not turn up good, as the chrome extension I wanted to try is not working.

Try with the next release coming this weekend, a lot more web extension APIs will be supported on iOS.

Mozilla's already done the work to make Firefox (the full browser, not just a Safari wrapper) run on iOS multiple times.

It wouldn't be that much more work to package it up and release it for side loading.
