I have written a bunch of utility functions in Javascript that I would like to 'somehow' be able to transparently/automatically plug into the web pages served by arbitrary sites (i.e., sites I do not control or have root access to).
I would like to know of at least 2 ways of achieving this. I have a vague idea that this could be done via a squid proxy server running locally on my (Fedora) workstation, but not sure. Because I'm on a Linux workstation, a simple, lightweight, commandline tool would also be welcome.
Greasemonkey enables you do specify scripts which are then automatically executed for specific web-sites.
