Containers are one of the best features Firefox has gained in recent years. They make managing multiple website accounts so much easier than trying to use multiple browsers or browser profiles. They are also useful for developers in lots of ways.

I don’t know why Mozilla doesn’t promote Containers more, they can’t even be used out of the box because they have to be enabled with an extension. It’s a far better feature than many of the other recent gimmicks like time limited colour schemes.

just in case someone is looking for that feature: it's a Firefox addon

omg i've left my 'work' stuff on edge because of this reason but i guess i'll migrate this to firefox too 🤯

You can also use that to separate spying websites. Eg. Any site with Facebook integration will think you are logged out, but when you go to facebook.com, it's open in a different container where you are in fact logged in, cuttin on Facebook spying on third party websites.

Oh that’s fantastic for AWS. I have a dozen chrome profiles for this type of behavior and it’s always sucked

Container Tabs sounds so useful, but fair warning to anyone else looking to check it out... I think it's kinda buggy. My sessions got all fucked up when I tried using it. I ended up removing it entirely and just going without.
