Actually I just checked and realized that it doesn't read bookmarks from specific sites. Does that mean it has something to do with cookies? I can re-save those pages but I will just duplicate them at my bookmarks folders.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

When the star is checking the Bookmarks Manager, it should be checking all entries in the folder. It could be the web page bookmark was removed. Or the wed address was changed. I am not aware of entries to the bookmarks being blocked, unless you have something blocking changes.

Thank you very much for your help!

You can check for problems with the places.sqlite database file in the Firefox profile folder to be sure.
