[Greasemonkey] Any method to transfer infromation between two pages

[esquifit]

Back at home :)
I've just checked 3 and it certainly works in FF from a GM script.  I
think it is simpler than 2, and avoid the slight overkill of 1 when
persistance of data is not required.  For instance, the following GM
script

---------------------------------------------
// ==UserScript==
// @name           Test passing data around via window.name
// @namespace      http://many.and.many/a/year/ago
// @description    Test passing data around via window.name
// @include        *
// ==/UserScript==

alert(unsafeWindow.name);
unsafeWindow.name = document.domain;
---------------------------------------------

will display the domain of the page that was previously loaded into
the current window/tab, but it will do so by reading a variable in the
current context.

This works in current versions of IE, I do not have FF here at work to see whether this also hols for Mozilla and GM.  The article is unfortunately in German, but even if you can't read it you'll be nevertheless able to follow the examples.  Another thing you'll have to take into account is that only letters, numbers and "_" are allowed for  window.name, so some ad-hoc escaping might be necessary (also illustrated in the article below).  The authors says that no apparent limit exists as to the size of the data that can be passed around, although it recommends no more that 1K.
