Separe is a Mozilla add-on that organizes tabs by introducing a new type of tab to help keep them tidy.
Another issue that arises with multiple tabs open is the default behavior of Firefox when opening a new tab or clicking a link to open a new tab. By default, these tabs are simply appended to the end of the list of tabs, leading to a cluttered and disorganized appearance.
This can become especially problematic when browsing multiple web pages and opening multiple links within each page. Instead of a cohesive and easy-to-navigate sequence of tabs, the result can be a confusing mess that makes it difficult to find the tab you need when you need it.
Overall, while Firefox does offer some useful tab management features, there are still some areas for improvement when it comes to keeping things organized and easy to navigate.
