If you find yourself overwhelmed by the number of bookmarks you have, especially if you have a number of them that is too large for you to handle manually, it may be worthwhile to look into an automatic solution. You don't need to download anything, just install a simple browser extension that will show you all the bookmarks in an organized list which you can then delete or keep.

The problem is that most solutions only work for Android phones, and even then, they're often not that good. 

How does it work?

All you need to do is to install it, open a web browser and point it to

You will see that it has created a list of all the bookmarks in the browser and it will only display bookmarks with the text

This way you can view all the bookmarks you have and delete those you no longer need.
