Firefox extensions

Tried a bunch of Firefox extensions. FlashGot's build gallery feature is cool, once I figured out how to get it to work. It would be nice if it could work on all links on the page. It gets confused by HTML entities, e.g., %20 for space. Thumbs is nice in the unusual case that every linked HTML page has a picture on it. Down Them All was usable. All-in-one gestures is nice when I remember to use the gestures. Clusty works correctly in the canonical example of "saturn" (but is useful as a website). Linky is cool, as is GoogleBar's "reverse link" search. Coralize this link extension is great.
