Hi list,

Would it be possible to emulate what the 'backgroud' page does
in the context of a "normal" Firefox extension by using Web workers?

In detail, WebExtensions dictates that each extension has a background
thread which runs independently of its foreground counterpart, and that
they notify each other by sending messages.

Web workers are quite the same thing: independent threads which can
send/receive messages to/from their creators.

So it seems "natural" to have a Web worker active for the extension's
lifetime which behaves the same way a WebExtension's background script
does.

Which kind of problems may arise in implementing the WebExtension's
semantics in a traditional Firefox extension?

Is there any exmple to look at which already does that?

Thanks
Marcello
