I have an existing collection of extensions on AMO, I can add and remove extensions from it and add my notes to the extensions, but if I try and edit the collection info (name, description and custom URL), it incorrectly errors, claiming I have invalid characters in the custom url. Even if I don't actually change anything when I hit "Edit", I can't save, I have to cancel out. I don't really care too much but probably someone should take a look at some point. There isn't a forum for the website specifically, so posting under FF desktop as that is browser I was using when this occurred (FF Win10 x86-64, Dev edition)
