1. Firefox Multi-Account Containers

Firefox Multi-Account Containers is an addon that allows you to keep parts of your online life separated into color-coded tabs that preserve your privacy. Cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously. Firefox Containers requires no restart after installation, so you can use it right away. Upon installing the addon, you will notice its icon on the top right corner of the browser. Click on this and you should get a drop-down menu as shown below:

Once you are done setting up the various containers, right click on the “New Tab +” button and select the another container to open.

You can now login to another account on the same website, like Google, Facebook, Twitter etc. Here are more details and benefits on using Firefox containers.

2. Private Window

If you don’t mind dealing with another application window, you can open a Private window in Firefox and login to another account of the same website. To open a Private window, press Ctrl + Shift + P or go to “Menu -> New Private Window”. This will open a new private session and you can use it like the standard browser. There is no limit to the number of Private window you can open, so if you need to login to more than one account, you can open multiple Private window.

Conclusion

Firefox Containers is great for multitasking and managing multiple accounts in the most straightforward way possible. It also protects your privacy as each container is shielded from your standard session. It may take some getting used to at first, but the functionality you get is worth the effort. If you want a fast way to see all your accounts in one go, this add-on will do the job.
