Multi-Account Containers is a major feature I can't sing the praises for enough. I use it all the time, both to isolate stuff to break cookie tracking, and to enable me to log into things with two different accounts without opening a separate browser, which happens more often than I'd have thought.


There's a few pain points with containers; whenever I'm browsing in a container tab, I wish CMD-T opened a new container tab, not my default tab. I haven't been able to find a setting for this :/

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

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.

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,

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.

Not exactly what you're looking for, but Temporary Containers (no longer maintained, fwiw) at least will open every new tab in a new temporary container that will be wiped after a configurable amount of time after closing.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

You don't need containers for this: https://total-cookie-protection-test.netlify.app/


When I was doing IT support for ~50 SMBs I was using multi account containers + temporary locations ALL THE TIME to log into customer accounts in various places, now I don't really have the usecase but the addons are still there for the rare occasion.


I love that feature, my only complaint is that it's an atrocious, confusing UX that has never synced correctly for me, which integrates ads for FFX VPN, and has been forgotten when it really needs to be added to the core browser.
