[UPDATE: I made another post for Chrome extensions][UPDATE the second: The popup with tags button now has a scrollbar. (Thank you to the anon who provided the code in the google doc.)]This is a tutorial for adding a Pinboard sidebar and custom Pinboard buttons to Firefox. Hope it helps some people!
One thing I really liked about the old Delicious was the Firefox addon. I use sidebars a lot, and I love customized toolbars. I didn't really use the Delicious toolbar, but Firefox allows you to drag buttons that you like into other toolbars (in my case the amazing All-in-One Sidebar, see
http://firefox.exxile.net/aios/index.php).
Pinboard offers only a very basic browser addon (no real toolbar and no sidebar), plus the bookmarklets that you can drag and drop anywhere you like. However, when I first got my pinboard account (back when Yahoo announced they'd shut down Delicious) I spent some time fiddling with the Pinboard bookmarklets and made them into pretty buttons. I also made a button for a Pinboard sidebar.* Now that more people are leaving Delicious for Pinboard, I figured these might be useful for other users.
( Screenshots and instructions under the cut )* Well. It's the Pinboard mobile version opening in your Firefox sidebar. Not a replacement for the Delicious sidebar, but Maciej (the Pinboard owner) has said that he will not be implementing a real sidebar anytime soon because it would require too much coding. So this is the best you'll get.
