Without a doubt, Greasemonkey has become my favourite Firefox extension. I’ve got lots of scripts loaded up. Here are some that everyone should find useful —
- Gmail Tweaks adds persistent searches to Gmail. Really cool.
- del.icio.us Auto-Complete makes posting stuff to del.icio.us easier. And it works with the ‘experimental’ interface too.
- Lickr is Flickr! without the Flash interface. I’m loving it!
- Google Butler is Mark Pilgrim’s script to ‘enhance’ Google searches. It does a lot of things. Check it out before installing.
- BoingBoing Butler does the same for Boing Boing.
- And you can finally fix Slashdot’s colour schemes. Really good on the eyes.
That should get you started. Look at the huge repository to find more scripts.
