Compatibility with secure pages and adblocker extensions
The main reason why I decided to go with a different site for my wishlist was because the wish button didn't work on all sites. I suspect it was due to some scripting being blocked by one of my other extensions, but those extensions give me security and peace of mind while browsing, so they take higher priority than this site. If it isn't possible to ensure compatibility with those extensions, it might be better to go to a more primitive method of adding items, just through a menu on this site.
