greasemonkey

I have a custom piece of Javascript which I would like to run on every web page from specific domains, or perhaps simply on every web page. (If you are wondering: it is not malicious. It allows to display formulas by using MathJax.) Is that possible? I tried including it in userContent.css, that of course did not work. A simple Greasemonkey script I tried did not insert it. Is it because of the security precautions? (Which would be very logical). Still, there should be a way to do it on the machine I physically control, by changing something in Mozilla chrome directory, shouldn't it? Anyway,

I'm using Greasemonkey and trying to add a rule in a specific domain. But it results in an error saying The operation is insecure . The code works fine on Chrome. The script runs on http://mydomain.com/test/test.php And the CSS file is http://cdn.mydomain.com/test/css/global.css My function: function css(selector, property, value) { for (var i=0; i<document.styleSheets.length;i++) { try { document.styleSheets[i].insertRule(selector+ ' {'+property+':'+value+'}', document.styleSheets[i].cssRules.length); } catch(err) { try // IE { document.styleSheets[i].addRule(selector, property+':'+value); }

I am using the following excellent userscript (for Chrome, Chrome's Tampermonkey and Firefox Greasemonkey). It's supposed to display movie ratings next to each IMDb movie link, but it stopped working properly. This is the complete script: // ==UserScript== // @name Add IMDb rating next to all IMDb links (+voter count) // @author Ali // @description Adds movie ratings and number of voters to any IMDb link. Modified version of http://userscripts.org/scripts/show/9174 // @include * // @version 2013-05-12 // @namespace http://userscripts.org/scripts/show/96884 // @grant GM_xmlhttpRequest //

I have a GreaseMonkey script that works on a site that uses frames as an integral part of its interface. This script leaks memory like a sieve, and I believe it is due to my use of addEventListener within one of the frames. Quite simply, I attach a variety of event listeners, then the frame reloads and I attach the event listeners, and then the frame reloads, around and around for hundreds or possibly thousands of iterations as you interact with various elements in this frame or others. By the end of it, Firefox has gone from ~300M of memory to as much as 2G (or crashes before it gets there).

I am trying to save a couple of images that are linked to by a webpage to offline storage. I'm using IndexedDB on Firefox and FileSystem API on Chrome. My code is actually an extension, so on Firefox I'm running on Greasemonkey, and on Chrome as a content script. I want this to be automated. I am running into problem when I retrieve the image file. I'm using example code from the article titled Storing images and files in IndexedDB , but I get an error: the images I'm trying to download are on a different subdomain and the XHR fails. XMLHttpRequest cannot load http://...uxgk.JPG. Origin http:/

I know Greasemonkey scripts are automatically wrapped in anonymous functions isolated in some way in order to prevent them conflicting with scripts in the page. Does the same happen with Chrome user-scripts? Yes, Greasemonkey scripts are normally wrapped in an anonymous function . And, Chrome userscripts apparently are too . But, more importantly, Greasemonkey scripts are usually 1 wrapped in an XPCNativeWrapper sandbox, while Google Chrome converts userscripts into extensions, and they operate in an arena that Google calls an "isolated world" 2 . So, you don't need to wrap your script code in

for some reason my Firefox4+GreaseMonkey Script loads jQuery twice. I copy'n'pasted the following snippet, the "test" alert shows twice. Regards var $; // Add jQuery (function(){ if (typeof unsafeWindow.jQuery == 'undefined') { var GM_Head = document.getElementsByTagName('head')[0] || document.documentElement, GM_JQ = document.createElement('script'); GM_JQ.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js'; GM_JQ.type = 'text/javascript'; GM_JQ.async = true; GM_Head.insertBefore(GM_JQ, GM_Head.firstChild); } GM_wait(); })(); // Check if jQuery's loaded function GM_wait() { if
