Ubiquity adds easy to use commands to Firefox. It’s dead simple to use: activate it with a keyboard shortcut (I use Ctrl-Space), then type in a command. The commands autocomplete, so you don’t even have to remember or type in the whole command. Some good ones:
weather <location>gives you the local weathertinyurl <URL>sends the URL to tinyurl and enters in the shortened URL at the current cursor location. (Great for Twitter!)twitter <message>broadcasts a message on twittertag <list of comma-separated tags>saves the current tab as a bookmark and assigns it the list of tagsemail <text> to <email address>starts a new email in Gmail with a link to the current web pageescape HTML entitiesreplaces all instances of greater than signs with > and all less than signs with < in the selected text–very useful for HTML-enabled forms where you want to discuss HTML tagstranslate <text> <from language> <to language>replaces the selected text in a website with a translation of that text into a new language.add to google calendar <event>adds an event to google calendar, e.g. “add to google calendar dinner with parents Friday at 5pm”listopens a list of all the commands Ubiquity accepts
Very spiffy.
