The two main plugins I really like are Colorful Tabs which allows me to have different coloured tabs depending on the site I'm on .. makes the multitude of tabs I usually have open easy to navigate.

The other was Tab Mixed Plus which had some fantastic features not the least of which was being able to close the browser and restore my session when I reopened (which is native to both Chrome and Edge with a setting turned on) .. multiple lines of tabs with a set number of rows displayed at a time and some nice customizing features. I have them back now.
