Chances are you have more than 50 bookmarks. Mainstream users have a hard time finding what they saved on their bookmarks. Except for being synced on the cloud. We are still confined to the same bookmark experience we had 20 years ago.
In contrast I can only sort the apps on my phone on to one of several pages, and to find one I have to flick through them looking for a particular icon. I don't even get customized text descriptions, let alone subfolders, customized icons...
I primarily save bookmarks so that they come up at the top of my autofill list. Most of them are a couple of keystrokes away.
