The Firefox Multi-Account containers are great: https://addons.mozilla.org/en-US/firefox/addon/multi-account...

Multiple profiles within a single window, visually distinguished by tab highlight color.

It looks like this doesn't allow you to separate history, addons, bookmarks, or move your current tab to a container. I am sticking with google for now.

You can use about:profiles or the profile manager (https://support.mozilla.org/en-US/kb/profile-manager-create-...) to handle that. The UX isn't as polished, but for just a handful of uses (work, personal, etc.) it's easy enough to make shortcuts which call `firefox --new-instance --profile <profilename>`.

You can use multiple profiles with Firefox, the UX for doing so just isn't as fleshed out as Chromium.

Create a new profile by going to about:profiles, and thereafter when you start Firefox it should present you with an option to pick which profile to use.

Yep. I love containers.

You can launch Firefox with different profiles (including navigation history, Firefox account, extension, etc) in the same machine. It's a bit cumbersome since you need to select the profile as a launch option (firefox -p) or launch it from "about:profiles", but it works.

What stops you from launching Firefox with the profile manager twice (there's a flag for that), and selecting the two profiles? It takes a couple of seconds to select the profile.

That is a good work-around. Multiple devices, systems, users, locations, and other factors makes selecting the current profile a pain.

@mmphosis: you can always link different profiles to different Firefox account so they all get sync between devices.

firefox -p launches firefox into the profile manager. firefox -p work -new-instance launches your work profile. What are you missing?

Thanks, this seems to work. I found the no-remote option when looking around, but accidentally lauching private_dot_com (nsfw) a couple of times at work instead of my private profile ended my testing with this last time.

Yup,

    c:\apps\firefox\firefox.exe -no-remote -profile "C:\profiles\some-clean-profile"

was my was-to-go method for testing various configurations.

Knowing about

    %USERPROFILE%\AppData\Roaming\Mozilla\Firefox\profiles.ini

is also often helpful, eg. when you want to move certain profile folder.
