Gibt's inzwischen andere Parameter um Scripts einzubinden?
Du hast im Ordner chrome die Datei:
userChrome.js
eingefügt?
Ja, meine userChrome.js ...
Code
/*
* userChromeJS
*
* The file userChrome.js can be used to customize the functioning of Mozilla's
* user interface. Usage and syntax follow below; for useful code snippets see
* http://mozilla.zeniko.ch/userchrome.js.html.
*
* Examples:
* setTimeout(function() { document.title = "A new title for every window" }, 2000);
*
* if (location == "chrome://browser/content/browser.xul") {
* alert("Script loaded in main browser only");
* }
*
* // DOMi window
* if (location == "chrome://inspector/content/inspector.xul") {
* // Move Urlbar box to main toolbar
* var tb = document.getElementById('bxURLBar');
* var el = document.getElementById('mbrInspectorMain');
* if (tb && el) el.appendChild(tb, el.firstChild);
* }
*
* NOTE:
* userChromeJS includes an 'import' function to facilitate file management.
* An absolute path or relative path with Directory name property token can be
* used, as follows:
*
* // Single file (javascript .js or overlay .xul file)
* userChrome.import("Full file path");
* userChrome.import("Relative file path", "Token");
* // All .js and .xul files in a folder will be loaded.
* userChrome.import("Full file folder path");
* userChrome.import("Relative file folder path/name", "Token");
* userChrome.import("*", "Token");
*
* NOTE:
* Absolute windows files and folders must be have backslash escaped:
* "C:\\Program Files\\Mozilla\\scripts\\myscript.js"
*
* Examples:
* // Import script in [ProfileDir]/chrome/scripts/myscript.js
* userChrome.import("scripts/myscript.js", "UChrm");
* // Import script in [Profiles]/scripts/myscript.js (share same script in
* // multiple profiles
* userChrome.import("scripts/myscript.js", "DefProfRt");
* // All .js or .xul in profile chrome directory
* userChrome.import("*", "UChrm");
* // Import overlay
* userChrome.import("C:\\Program Files\\Mozilla\\scripts\\myOverlay.xul");
* // Import everything in Desktop folder /scripts
* userChrome.import("scripts", "Desk");
* // Perhaps the only thing you need in this file..
* if (location == "chrome://browser/content/browser.xul") {
* userChrome.import("scripts", "DefProfRt");
* }
*
* NOTE:
* For a full listing of directory tokens see the two links found here:
* https://developer.mozilla.org/en-US/Add-ons/Code_snippets/File_I_O#Getting_files_in_special_directories
* // What's the path for a token? This will print it in the console.
* userChrome.log(userChrome.getAbsoluteFile("Desk").path, "getAbsoluteFile:'Desk'");
*
* NOTE:
* userChromeJS includes a log function, invoked as follows:
* userChrome.log("string1"[, "string2"])
* Example:
* userChrome.log("hello world!", "myscript.js");
* Results in a console message:
* 2009-05-22 18:07:40 userChromeJS myscript.js: hello world!
*
* NOTE:
* The date format for the userChrome.log console logger may be user defined:
* Example:
* userChrome.dateFormat = "%Y-%m-%d %H:%M:%S";
*
* NOTE:
* The default charSet is "UTF-8"; for code using the 'import' or
* 'importFolder' functions to manage files, the charSet for subscript loader
* may be user defined, prior to calling the import or importFolder functions:
* Example:
* userChrome.charSet = "UTF-8";
*
* NOTE:
* Scripts are stored in a startup cache and loaded from it.
* After a change in userChrome.js you heve to restart Firefox with clearing
* this cache to make sure the changed file is read.
* By default this applies to imported .js files too. You can bypass the cache
* for these scripts with this statement BEFORE any import statement:
* userChrome.ignoreCache = true;
*
*/Den gibt es nicht mehr.
OK, Danke. Heisst, man braucht per about:config überhaupt nix für User-Scripte einstellen?
Danke einstweilen.
