If you revisit a site that you tried to bookmark, is the star yellow? If the star is yellow, the site has been bookmarked. Clicking on the star once saves the bookmark in the "Unsorted bookmarks" folder which is not visible in the bookmarks menu, clicking on the star a second time allows you to edit the bookmark so you can move it to the folder of your choice. See the [[bookmarks]] article for further details. If the site is not being bookmarked at all, see the [[bookmarks not saved]] article for details of how to resole this issue.
