I've been using Firefox Sync for some time and am generally quite happy with it, but there is one annoyance: when I delete a bookmark on one computer, the bookmark is still present on other computers, even after fully syncing. The deleted bookmarks get moved to the end of the folder they were in prior to deletion. As background about my use case: I have a bookmark folder where I add articles, blog posts etc. that I plan to read later. When I have read them I delete the bookmarks. But if I read an article on my work machine, say, and delete the bookmark, the bookmark will not go away on my home machine. Is there anything I can do to make deletions on one synced machine reliably propagate to all synced machines?
