> I also wish there were more keyboard shortcuts for opening links in specific containers, or re-opening a current tab in a different one.

fwiw, there are add-ons that allow you to do this - in one way or the other (Container Hotkeys https://addons.mozilla.org/en-US/firefox/addon/container-hot... for example).

but out of curiosity,

> I know you can set certain domains to always open in certain containers - fine for Facebook, when I occasionally have to use it - but annoying when I'm trying to do things in different (e.g.) Bluesky accounts.

on this one btw, the Containerise extension i talk about (if it wasn't clear) allows you to also map "portions" of the url in specific containers. so /u/0 in one /u/1 in another; ofc, this requires the service/website to distinguish the accounts via the url. i do this for github a lot (work repos in specific containers)

Very cool, thank you - I'll check out the hotkeys add-on!

The other extension won't work for me, mostly - for example, Bluesky doesn't give me different URLs depending on who I'm logged in as. (Which is the correct thing to do, but it does make my life slightly harder. :/)

edit: oh, nevermind. It looks like it adds a single hotkey to open a new tab in a single, specified container. I was at least hoping the hotkey would work by opening a new tab in the same container I'm in currently :/

Not having subdomains work for container assignments is a baffling design decision. It's a well-known issue and oft-requested feature that the devs seemingly have no plan to fix. It's incredibly frustrating.

> whenever I'm browsing in a container tab, I wish CMD-T opened a new container tab

Not exactly what you're looking for, but Temporary Containers (no longer maintained, fwiw) at least will open every new tab in a new temporary container that will be wiped after a configurable amount of time after closing.

Open a new tab for a certain container with Cmd-1 (or Cmd-Shift-1, I forgot) for the first container in your list, with 2 for the second, etc.
