A tabset is a collection (a set) of tabs.For example, when you check your holiday destinations and matching hotels, you can create a "holiday" tabset to keep track of your research.
An open tab is simply a tab which happens to be open in your browser's current window.You can access them either via the browser's tabs (of course), or in the left 'open tabs' drawer.
Spaces are a way to organize tabsets. You can create a space for your private stuff and another for work. Spaces can share tabsets, i.e. a tabset can appear in none, one, or many spaces.
