how do I delete a bookmark from macbook pro?

Sorry I think I have shown you Firefox on windows

on a Mac

Use the "Bookmarks" menu. The first item is "Show All Bookmarks" select this. The Library window pops up, click on Bookmarks Menu This should show all bookmark folders and bookmarks not in folders. Then highlight the bookmark you want to remove and hit the delete key

Depends on which browser are you using

see

click bookmarks, organize bookmarkss,bookmark menu,highlight the bookmark you want to get rid off, delete
