I used the Amazon Assistant browser extension exclusively to add stuff from the web to my wish list for later. It was like a handy shopping bookmarks tool for me, though the rest of the extension's features sucked and were annoying. Unfortunately, Amazon Assistant was discontinued at the end of March and I can't use this function anymore.

So I go to my Amazon wish list on the web to manually add instead, but I can't find any sort of "Add" button for non-Amazon links. Am I blind or did they take it away? You can still add Amazon products to wish list from the Amazon product page, but I can't find a way to add links from elsewhere on the web.

I don't want to do any of this crap from mobile, so a web/desktop solution would be preferred. Any ideas?
