> 3. Firefox also has completely separate profiles, in addition to container tabs. The UI isn't as polished as in Chrome, but it works: https://support.mozilla.org/en-US/kb/profile-manager-create-...

Chrome allows users to simultaneously run multiple profile instances, each with it own profile. Firefox didn't seem to support that.

https://addons.mozilla.org/en-US/firefox/addon/multi-account... (or a similar addon) might bring me back to using Firefox.

With Chrome, one set up a profile shortcut to a given profile, and then all tabs/windows within the instance corresponded to the same profile. This meant hitting Ctrl+T to open new tabs, rather than having to click and dig through a menu to pick the right profile.

I'd like the containers addon to support easy shortcuts. Maybe on hitting ctrl+t, one can then press 1-5 (or some other selector) to determine which profile the new tab opens in. Alternatively, more safely and less confusingly, just having windows sticky to a specific profile, so all new tabs predictably open into the same profile.

Firefox does support multiple isolated instances, just without a prominent UI. You can use the Profile Manager (https://support.mozilla.org/en-US/kb/profile-manager-create-...) or command-line flags to launch and manage separate profiles.

The UX around multi-account containers is still being worked on, but the contextualIdentities WebExtension API (https://developer.mozilla.org/en-US/Add-ons/WebExtensions/AP...) allows add-ons to interact with containers, so a third party developer could create exactly the experience you've requested.
