Another Firefox hack: make your own sidebar

I love how Firefox lets you use any web page for your sidebar. Here
I've assembled a bunch of my favourite bookmarklets. Works great as a
Firefox sidebar.

Perhaps the coolest one is the text-to-speech bookmarklet (TTS) --
select some text, then click TTS.

Other interesting ones:
- Amazon - search Amazon for the selected text
- GoToSelectedURL - open the url given by the selected text
- HighlightRegexp - enter a regular expression to highlight
- Up - go to the parent folder of the current URL
- Top - go to the top-level domain of the current URL
- Wikipedia - search Wikipedia for the selected text
