Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
- Added @noframes metadata imperative. (#1859
- Added a "New User Script" button into the Add-ons Manager. (#1972)
- Scripts will always execute (or not) based on their original URL, before any possible history.replaceState() changes by the content scripts. (#1970)
- Script @name and @description values can be localized for multiple languages. (#1963)
- User scripts will never execute with chrome privileges. (#1988)
- Improved Drag-and-Drop into the Add-ons Manager. (#1980)
- Correctly show all Unicode characters when selecting View Script Source. (#1940)
- Repair GM_xmlhttpRequest() for XML type responses. (#1937)
- Fix the position of tabs created with GM_openInTab(). (#1897)
- Do not falsely trigger the install dialog when e.g. editing a script via the GitHub web interface. (#1875)
- Fixed an error when pressing cancel in the install dialog. (#1862)
- GM_log() no longer truncate at NUL bytes. (#1061)
- 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.
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.
- 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.) (#1908)
- GM_addStyle() now returns the created element. (#1892)
- Update checks will attempt to read a .meta.js file for scripts installed from any site on the internet. (#1885)
- Remove all references to the now defunct userscripts.org website. (#1884)
- Turn on Firefox Sync support by default. (#1857)
- GM_xmlhttpRequest() can set the resposeType parameter on the request. (#1834)
- A rare NS_ERROR_MALFORMED_URI error when running certain scripts has been resolved. (#1930)
- Fixed a bug when parsing @match rules which could destroy configuration state. (#1912)
- A bug fix for the @match metadata, to correctly match bare domain names. (#1899)
- The database where persistent values are stored correctly vacuums its unused space. (#1879)
- A relative @require URL will now work correctly. (#1874)
- The options window will flex to fit on small (or large) screens. (#1871)
- Greasemonkey's integration with Firefox Sync should no longer cause unnecessary prompts when a master password is set. (#1852, #1870)
- Greasemonkey sends headers when making script update checks. (#1824)
- Allow correct installation of even scripts with invalid duplicate UTF-8 BOMs. (#1823)
- Certain script install/uninstall actions could cause Firefox to fail to open (Windows only). (#1833)
- All scripts installed from userscripts.org will use HTTPS by default, so that automatic updates will work. (#1800)
- All stored script values (GM_setValue) move from the (soon to be limited) Firefox global preferences store into a per-script database, so that this limit will not break scripts. (#1798)
- Log a more understandable error if GM_getResourceText is called with a nonexistent resource name. (#1796)
- User script installation will continue if the @icon is unavailable. (#1793)
- Firefox Sync support, to keep installed User Scripts the same on all your browsers. (#1573)
