Bugzilla

I see the following in the console:
```
console.error: (new ReferenceError("WebAssembly is not defined", "resource://gre/actors/TranslationsParent.sys.mjs", 2710))
```

Further I can find the construct `return WebAssembly.validate(` in the ml/content/Utils.sys.mjs.

Better way will be adding of the following in detect Wasm feature functions (which is fixes the refresh button):

```

I don't know the reason why JavaScript exception in the translation code affects chrome's buttons.
