New in Greasemonkey 4.0 (Nov 3, 2017)

  • Greasemonkey has been a Firefox extension for well over a decade, with version 0.3.5 dating from 2005. We've grown and changed a lot over that time. With the upcoming Firefox 57 release, we need to change even more. Mozilla is completely replacing the extension system in Firefox, to align with the budding Browser Extension standard, based on/shared with Google Chrome.

New in Greasemonkey 2.0 (Jun 18, 2014)

  • Backwards incompatible changes:
  • For stability, reliability, and security the privileged sandbox has been updated to match the new changes to unsafeWindow for the Add-on SDK. In order to write values to unsafeWindow you will need to use the new methods cloneInto(), exportFunction(), and/or createObjectIn().
  • The @grant none mode is now the default, and grants will no longer be implied when not explicitly provided. See the post Sandbox API Changes in Greasemonkey 2.0 for more detail.
  • If your script already specifies @grant none, these changes will not affect you. If your script does not interact with unsafeWindow, these changes will not affect you.
  • Otherwise, these changes will break some scripts. These scripts will need to be updated to work correctly again. We don't take breaking changes lightly. It's been just under two years since version 1.0 when we last introduced major changes, and it these particular changes are both important and valuable in the long run.
  • Enhancements:
  • Greasemonkey will only use explicit @grant metadata, it will no longer sniff for implicitly used APIs. (This change takes effect at install time. Currently installed scripts will continue to function as normal until they are updated/edited/reinstalled.)
  • GM_addStyle() now returns the created element.
  • Update checks will attempt to read a .meta.js file for scripts installed from any site on the internet.
  • Remove all references to the now defunct userscripts.org website.
  • Privileged scripts' event listeners will run, even when content JavaScript is disabled.
  • Turn on Firefox Sync support by default.
  • GM_xmlhttpRequest() can set the resposeType parameter on the request.
  • Fixed bugs:
  • A rare NS_ERROR_MALFORMED_URI error when running certain scripts has been resolved.
  • Fixed a bug when parsing @match rules which could destroy configuration state.
  • A bug fix for the @match metadata, to correctly match bare domain names.
  • The database where persistent values are stored correctly vacuums its unused space.
  • A relative @require URL will now work correctly.
  • The options window will flex to fit on small (or large) screens.
  • Greasemonkey's integration with Firefox Sync should no longer cause unnecessary prompts when a master password is set.

If you are opted out of automatically installing updates, there should be an "Updates" tab in the Add-ons Manager where you can review and optionally install them.
  • Bug fixes:
  • Fix updates (see enhancement above). Especially: a bug that installed updates far too often, when they should not have been. (#1646, #1647)
  • Fix an obscure case which could cause Firefox to crash in Ubuntu Linux. (#1632)

New in Greasemonkey 1.3 (Sep 28, 2012)

  • Enhancements:
  • The "Show Script Source" button in the install dialog is enabled as soon as the script source is downloaded. (#1640)
  • Use new style non-modal popup notifications where old toast style notifications were used. (#1563)

New in Greasemonkey 1.1 (Sep 10, 2012)

  • Enhancements:
  • Compatibility with upcoming Firefox changes.
  • Bug fixes:
  • Fix a Firefox crash caused by a bad greasemonkey-script: URL (i.e. passing the empty string, or a nonexistent resource name to GM_getResourceUrl().) (#1623)
  • Re-fixed the setTimeout + alert issue; it popped up again in the grant none case. (Note: Firefox 16 fixes this for real. This just applies the same old workaround.) (#1620)
  • Fixed the character encoding of the es-CL translation. (#1616)
  • Fixed the display of the "Enabled" check mark in the monkey menu. (#1611)
  • Fixed the "Show Script Source" button for some scripts. (#1609)

New in Greasemonkey 1.0 (Aug 24, 2012)

  • Enhancements:
  • New metadata, @grant, specifies which special APIs a user script will
  • have access to. Specifying "@grant none" means no special API access, and
  • thus no security restrictions.
  • The metadata @unwrap has been removed, as being unwrapped is now the default.
  • The wrapper will still be applied to scripts that have a "return" statement outside of any function, but this may be removed in the future, so make sure your scripts don't do this.
  • Require at least Firefox 14.0 (no more Firefox 3 compatibility).
  • Scripts that "@run-at document-start" have a valid document object to modify, E.G. for adding tags; but still before any part of the document is loaded.
  • GM_xmlhttpRequest() accepts a "timeout" option.
  • GM_getResourceURL() works with a special protocol handler. (This is more
  • efficient/faster than the data: URI encoding used previously.
  • The standard Firefox web developer console works for "console.log()" et al.
  • Error reporting is much more consistent and obvious than in the past.
  • Bug fixes:
  • Scripts with missing or broken "==UserScript==" metadata will work.
  • The "alert()" workaround is not applied for Firefox versions that do not exhibit this bug.
  • When downloading a script not encoded in UTF-8, display an error message to the user (rather than failing silently).
  • The "show script" button in the install dialog is disabled until the download of
  • the script file is complete.

  • Enhancements:
  • Script updates install automatically. (#1442)
  • In 0.9.12 we added update checking. In 0.9.13 updates install automatically, but there's still some discussion over how to handle this best (#1455), so checking is still not enabled by default.
