When I look at your extensions list, Delicious Bookmarks is still there. Is that the one you are looking for, or the newer one here: https://delicious.com/tools

Attached is a screen shot from my previous macbook pro and one from the new one. The first image has the old delicious sidebar, and the second just has a side bar with the delicious page opening in it. ANd the firefox version is the same (31) So how do I get the old side bar with organized tags and all to work on my new laptop. It seems to have just gone and Ive tried different things to get it back. Essentially I want the whats in the first image with the sidebar on the left and tags etc.

Please help!

Sorry, Delicious Bookmarks 2.3.4 was removed from the Add-ons website by the developer a little over 4 months ago.

There is a list of mirror websites for that extension here: http://www.basurablogger.com/delicious-bookmarks/

But how come its still works on one computer and not on the other then? Image attached.

Thanks, I tried using the xpi file from the link, but it still shows the same delicious side bar. : ( But how come it stills works on one computer and not the other? Like this is still working.

Just a guess. Delicious Bookmarks 2.3.4 was installed on the old Mac, but you installed the new Firefox Social API Extension on the new retina Mac ??

The newer Firefox Social API Extension from here - https://delicious.com/tools - isn't the same extension as Delicious Bookmarks 2.3.4. It looks and works differently.

Ok. I tried installing the Delicious Bookmarks 2.3.4 xpi file on the new mac as well, but doesn't work. I guess its just gone then. : (

Thank you for the help though!
