How's that for a beefy Firefox status bar...
- GreaseMonkey fixes up, styles and rewrites web pages
- Piggy Bank collects semantic data from visited pages on demand
- Beagle stores a searchable index of all pages visited, and shows which of those pages link to the current page
- Feed Your Reader autodetects linked feeds and sends them to a feedreader
- Adblock, not surprisingly, blocks adverts.
