the Stumblng Tumblr’s answer to both questions was “yes”
well, via this, the Stumblng Tumblr got to this article from Macworld
by all means, read the article, but the Stumblng Tumblr’ll just explain what, after reading the article, he did finally to get his bookmarks into alphabetical order in the current Linux version of Firefox (2.0.0.14)
he went to Bookmarks > Organize Bookmarks… and got the Bookmarks Manager open; he then clicked on Bookmarks at the top of the left panel; having done that, he then switched to the right panel and selected a bookmark; having selected it, he then right-clicked on it and selected Sort By Name
after he did that, he closed the Bookmark Manager and found that, when he next opened his bookmarks, they were all in alphabetical order!
