API to check whether an URL is assigned

[stoically]

Hi,

@shvchk asked if it would be possible to support your Add-on in combination with mine here: stoically/temporary-containers#15

For that to work properly I'd need an API to ask your Add-on whether a specific URL is assigned. Here's how Multi-Account Containers is doing it: mozilla/multi-account-containers#1130 (comment)

Would you be up to implement something like that or accept Pull requests implementing it?

Best regards

I am heppy for you to create a PR.

Before I start working on this it would be good to know in what way you would want to see it implemented. It would require adding runtime.onMessageExternal - now the question is, who should be able to get an answer? The options I see are:

• Adding the management permission and checking for contextualIdentities permission
• Adding a whitelist that has to be manually maintained
• Just answering whoever asks

I think it best to lock it down to specific id and manually maintaining it. The way I see it is that this extentions won't change much from what it is now.

Just wanted to thank @stoically and @kintesh for working on this and container stuff in general. You guys are awesome! 🤘

@kintesh Would you mind releasing a new version? Currently I can't use containerise because of this.
BTW: Thanks for your extension, it is really the last missing piece to get a smooth container experience.
