Firefox Multi-Account Containers have definitely made my internet browsing, both business and personal, a very pleasant experience. Even my app cleaners agree because I don't clean hundreds of junk, privacy, and registry files.

I gave Firefox Multi-Account Containers a 5 star rating because it's UI is easy to use, very intuitive of the Developer's to include color-coded cards that I create specific to my needs. You can even use your password manager without a hitch while inside of the color coded tabs.

You are also able to right-click on a new or current tab to open a context menu; and, given the option to re-open your tab, select your specific folder, and the new tab is underlined with your color--let's you visually know what they are.
