Does Pinboard have a Firefox extension (or plans for one)? I'd love to have an alternative to Delicious, but the smoothness of their Firefox integration is so good it not only keeps me using Delicious, it also keeps me using Firefox. Some reasons I like it so much: * Ctrl-D to bookmark, just like vanilla Firefox * Ctrl-D on an already-bookmarked page to edit tags / description for that page * Ctrl-B for an always-up-to-date bookmark pane, with FAYT by title or tag * "Open in tabs" for any tag (I use this daily for the webcomic update-checking ritual, and occasionally for actually useful things) * Awesome Bar integration by title or tag (bit flaky but great when it works) * Dropdowns for user-defined "favourite tags" in a menu bar (this plus a "todo" tag is almost as good, for me, as a natively supported "toread" feature)
