Looking for SeaMonkey extensions

I had a couple of very useful extensions for the 1.X versions of SeaMonkey. The developers haven't released any 2.X compatible versions and I haven't found any equivalent to them. The 2 that I most want to duplicate are diggler .7 and dictionary search 0.9.3

Diggler added a very useful drop down menu to the address bar which I'd very much like to have again. Screenshot of menu. The last 2 items "find page in archive.org" and "find page in Google cache" were very handy.

The dictionary search extension allowed me to add 4 custom dictionary or search entries to the context menu. Here's a screenshot of its configuration in the preferences menu.
Does anyone know of extensions that duplicate these for the 2.X versions of SeaMonkey?
