I wanted a simple addon that lets me color-code tabs so i can easily distinguish between them. E.g. I have 5 tabs opened with 5 different issues in Azure Devops and want one i'm working on to be red and onother to be blue so when I switch beween applications and many other tabs I will always easily wind that one important tab. I don't want the whole browser tab bar to change color when i select the tab, I just want the small tab to be colored, without having to select it. This addon works but is completly useless for me.
