Of course, there are thousands of add-ons developed for Firefox. But among these plugins, there is a plugin called ColorfulTabs , which I love and which makes the browser look stylish. What is the benefit? If you say so, it is of no use. It just makes every tab you open in your browser appear colored, so it makes your browser a kind of colorful. Thinking that there may be those who want to use it, I wanted to share the plugin. Anyway, the plugin link is below. You can install it by clicking the link and downloading the add-on.
