In windows I can easily delete a FF bookmark. To do so I just click on Bookmarks button. Then a list of bookmarks appears and I just right click on the bookmark which I want to delete and once a menu come with delete option I just click on this. Thats all. But in Ubuntu I see bookmark deletion is not that easy. If I open a list of bookmark and then right click on the bookmark browser actually takes me to the link as I did a left click! To delete a bookmark I just click on Bookmarks>Show All Bookmarks>All bookmarks>Bookmarks menu and then finally right click on the bookmark I want to delete and then click one the newly appeared delete menu. This sucks time. What is the easiest way to do so? Or I guess my mouse buttons are not properly setup?
You are probably refering to using the bookmark menu from the "global menu".
I can confirm using the bookmar icon in the firefox toolbar, the bookmark sidebar and the bookmark manager works as you describe.
