The Twitter Firefox plugin

The Twitter plugin for Firefox has three main features:
  1. Address field:
    • Type a user name (such as @2ality) in the address bar to go to the corresponding Twitter page. There is no completion help, you have to type a complete name and hit return before you see anything.
    • Type a hash tag (such as #travel) to start a search.
  2. Search field: Twitter becomes one of the search engine options (in addition to Google etc.)
  3. App tab: If you add Twitter to Firefox as a permanent app tab, that tab lights up when new tweets arrive.
These features are useful, but I expected a bit more (e.g. live search for user names while you type). The best visual description is the welcome page that opens after installation. Installation does not require you to restart Firefox.
