Bookmarks don’t work like this. You are suggesting that an attacker could identify your traffic on the TOR network because of the bookmarks you have on your browser. This simply isn’t possible.
Why?
Because bookmarks are stored locally. That information isn’t sent over the network when you visit sites. They don’t function like cookies. A bookmark is nothing but a link saved on your computer, by your browser application. Essentially it is exactly what you are trying to create, a way to open a saved link that is only stored on your file system. Just because a browser manages something, doesn’t mean every website you visit can see it. A browser is an application on your computer like any other. The only thing an attacker might be able to see is what it sends over the network.
TL;DR
You don’t need to do this. Bookmarks are safe.
