Opening a website inside of a specific container?

[hf02]

I use two Discord accounts, and I would like to be able to use them in the same profile so I can keep my extension's settings the same across them.

I figured I could use this using containers, but I don't see a way to launch a website inside of a specific container. Is there a way to do this?

Containers with PWAs currently have some problems (#399) that I don't know how to fix, so unfortunately, I think this is currently not possible.

You will probably have to use multiple PWA profiles for now...

I found a decent workaround that's been working well for me, using the extensions Redirector and Multi-Account Containers.

What I did:

1. Come up with some URL that doesn't point to anything to serve as the start URL. For my main Discord account, I used https://discord-1.firefox-pwa.internal/.
2. Open that PWA. It should just be an error page, saying https://discord-1.firefox-pwa.internal/ failed to load.
3. Add that URL to Multi-Account Containers. So, when you navigate to https://discord-1.firefox-pwa.internal/, it automatically opens it inside of its container.
4. Use Redirector to redirect the https://discord-1.firefox-pwa.internal/ to the actual site URL, which in my case is https://discord.com/app.

So now, when I open the PWA, it launches in its specific container.
