Is it possible to give a custom name to a browser window on OS X? Is it possible to give a custom name to a browser window on OS X?

Perhaps by using a Window Manager that has this feature? If yes, which one has it?

The motivation for this question is : I have 100 browser tabs open, all on different topics. It would be great to cluster these 100 browser tabs into different browser windows, each having a meaningful name. 

For example : 


1st browser window for cat pictures named "cat pictures", having 10 tabs open about cats
2nd browser window for Haskell programming, having 10 tabs about Haskell open, named "Haskell"
3rd browser window for Buying a new meachanical keyboard, where I have 10 different tabs open about different keyboard review sites...
named "keyboard"


Any idea how to do this on OS X?
It is possible with this extension for Firefox:
