Doesn't work. Either says there's a problem and asks to close and restart, or, on the rare occasion it does actually load, it hangs whenever I try to do anything within the plug-in. This has happened in both Firefox and Chrome, and on multiple systems.

On top of that, it's a bloated plug-in that tries to do way too much. It was nice when it just worked to add off-site things to my wishlist, but now it's slow and cumbersome to use.
