Let me confirm pre-condition. Did you enable javascript.options.shared_memory feature flag? By default Firefox does not enable it due to security reason as I described in README.md.

Hi @rhysd, I am facing the very same issue. I have enabled the javascript.options.shared_memory feature as directed in the README. I've also tried this on a fresh profile and on new installations of Firefox on different machines. In all cases there is a black page. Additionally, Chrome/Chromium works fine for all machines.
I am fairly certain that this is not working at all in the latest versions of Firefox.
Since I am not particularly familiar with wasm, I am unable to determine the source of the problem myself; would it be possible for you to run some tests on Firefox yourself? Thanks.
Thanks for the confirmation. Currently I have few resource for new project, but I'll try this (hopefully) on this weekend.
@digg33 The "should be an object" error is related to Vim Vixen, not vim.wasm
