I’m currently having some trouble compiling the IPFS browser extension, both for Firefox and Chromium. Whenever I run either `npm run dev-build firefox` or `npm run dev-build chromium` it gives this:

```auto
yarn install v1.22.10

and it just stays there forever, waiting for `ursa-optional`.  
Any help would be appreciated.
