I use them in three ways: My most used bookmarks live on my bookmarks bar in Firefox with the text removed, so they are just icons of the favicon.gif from the server, screenshot example here[1]. The lesser used ones live in the "Folders" folder under a tree style arrangement. The third method is via the "ReadLater" folder which contains links I didn't have time to fully read right away, and acts as a sort of manual version of Pocket or similar apps.
