incompatible with current Delicious Bookmarks (EDIT - proven to be Delicious' code mistake) Rated 5 out of 5 stars
I used to love this extension, but I've had to remove it since I started using Firefox 3, because Add Bookmarks Here 2 and the Delicious addon don't work together.
You get something like this when you try and bookmark with them both installed:
ASSERT: Invalid menuitem in the folders-menulist
The current alpha version of Daniel Lindkvist's version of this also has problems with Delicious and Firefox 3, but they are easier to deal with. Lindkvist's version simply bypasses calling Delicious altogether, which is annoying but not as bad as a big error message. And with Lindkvist's version installed you can still manually add delicious online bookmarks under the delicious pulldown menu.
I'd PREFER to use ABH2, but for now... I can't.
EDIT - The bug has been proven to be Delicious' fault. Good work by the author provoking that so quickly. I'm raising my rating back to 5 stars.
