Greasemonkey

Greasemonkey is a Firefox extension allowing powerful user defined javascripts to be arbitrarily run on any page

Greasemonkey

Greasemonkey is a Firefox extension which allows the addition of "user scripts" to any web page. These scripts can alter the page's behaviour, add useful information, etc. A large number of scripts are available, and User Scripts lists even more.

Scripts

I've written/adapted a couple of Greasemonkey scripts (nothing too complicated):

Gmail Attachment Reminder
Attempts to remind you if it seems you meant to attach a file to a message but have forgotten to do so. New version (currently beta) compatable with the new Gmail interface (and should still work with the old version, though that's untested)
Gmail Attachment Reminder (Old Version)
Reminds you if it seems you meant to attach a file to a message but haven't. Originally based on this script but updated to support both send buttons, rich text, plain text, replies and forwards. Also checks the subject line. Thanks to Gina Trapani of Lifehacker it's now easy to change the word stem through the greasemonkey menu (for non-english checking for example). Separate multiple triggers with a pipe | Not compatable with the new Gmail interface
Ricorda Allegati per Gmail
Se trova la parola "alleg" nella mail ma non trova alcun allegato, chiede se si debba inserirne uno (naturalmente si avranno dei "falsi positivi" per parole come allegria, allegorico, ecc.). Originariamente basato su questo script (http://userscripts.org/scripts/show/2000), è stato poi aggiornato per includere il bottone di invio, controllare anche il testo formattato ("rich text"), il formato "solo testo", le risposte e le mail inoltrate. Controllare i commenti per sapere come aggiungere altre parola da controllare (si tratta di una semplice "regular expression"). (thanks to Cristiano Tagliabue for the translation)
Last.fm Add Searches
Adds links to search a number of sites for artist to last.fm. See the Options entry under Tools->User Script Commands to set which sites links are added for. It shouldn't be too difficult to work out how to add additional sites to the script.
MusicBrainz.org Searches
Similar to the last.fm searches, adds links to various search engines and torrent sites to MusicBrainz.org
Last.fm Add Torrent Links
No longer supported. Superseded by Last.fm Add Searches. Based on another script, this adds links to last.fm search for torrents on The Pirate Bay and Torrent Reactor. Unlike the original script is does so on all pages, not just the user profile ones. Now also links to Jabberwalker
MozillaZine Forums Mark all read Redirect to Index
The most unwieldy title in the world! When reading MozillaZine Forums, this will make clicking Mark all topics read redirect to the forums index, rather than the topic you've just been reading (which I find annoying)
Trainline Buy Tickets Autologin
See this blog post for something of an explanation
FlickrLeech Magnifier
Adapted from the Flickr Magnifier script, shows a larger version of the photo when hovering over a thumbnail on FlickrLeech
Add Totals To soccerbase Tables
The league tables on soccerbase.com show home and away stats separately. I often find I want to know total wins, draws etc. This script adds the appropriate columns, and also introduces a simple hover effect to highlight the row you're over
