How Does the @grant Directive in Greasemonkey 1.0 Cause jQuery Conflicts with Websites?

jQuery Conflicts with Websites Using jQuery in Greasemonkey 1.0

Greasemonkey 1.0's introduction has brought forth an unexpected problem for users who rely on jQuery in their Greasemonkey scripts when interacting with websites that also employ jQuery. This issue stems from the implementation of the @grant directive.

The conflict arises due to the grant directive's functionality, which influences how jQuery is loaded and interacts within the script and the visited web page. Previously, Greasemonkey scripts primarily ran in a sandboxed environment, preventing potential conflicts. However, the @grant directive modifies this dynamic, allowing for potential collision with jQuery present on external websites.

To resolve this issue and restore the sandbox functionality, users can revert to the previous method of operation by including specific @grant values. By amending the script's metadata block with the following lines:

// @grant       GM_addStyle
// @grant       GM.getValue
// ==/UserScript==

This approach ensures that the sandbox is reinstated, enabling the script to function seamlessly without conflict, and preserving compatibility with other proficient extensions like Tampermonkey and Violentmonkey.
