One of the main strength of firefox is it’s plugin eco-system. Though there are many alternatives to firefox, there are very less alternatives to the firefox plugins.
Following are the extensions or add-ons i use with firefox:
– Tabbed browsing. (Provides lots of tab control options)
– IE tab (Mainly to view sites which doesn’t show properly in firefox)
– Fox Clocks (To view the time of different timezones across the globe)
– Delicious Bookmarks (To integrate into my delicious account)
– TamilKey (To type in tamil)
