Ever since the new Greasemonkey 1.0 was released a few days ago, every site that has jQuery and where I use jQuery in my Greasemonkey script do not run my script properly. T
Had the same problem.
Since GM version 1.0 , all my scripts that @require jQuery, running on sites that also uses jQuery stopped working.
I know, I could try something like $ = unsafeWindow.$ , but that is not the point.
The point here is that they used to work, and now they wont.
Adding @grant GM_log fixed them.
