Firefox 4 lets you report when something makes you happy or sad. It's a very cute idea (although looking at the actual submissions can also make you quite sad). I wondered how long it would take until I had to use it, but here it is:
You couldn't store a bookmark without a name in previous Firefox versions, but you could delete it afterwards. After that you would only see the favicon of the bookmark on your toolbar, which saves LOTS of space.
However, someone must have thought that this was unwanted behaviour and decided to display the URL if there is no name. Messing up my toolbar
Yes, you can still use a simple space in the name field, but that still makes your icon 50% longer than it should be.
