version 编辑

"version": "0.1"

Version of the extension, formatted as numbers and ASCII characters separated by dots. For the details of the version format, see the Version format page. 

You can inspect the add-ons linter code to see how extension versions for Firefox are validated.

Note that the syntax defined for Chrome's version is more restrictive than that used by Firefox:

• values for version that are valid for Chrome will always be valid for Firefox
• values for version that are valid for Firefox may not be valid for Chrome

To obtain your extension version in your JavaScript code, use:

console.log(browser.runtime.getManifest().version);

Example

If the manifest contains:

"version": "0.1"

To obtain your extension version in your JavaScript code, use:

console.log(browser.runtime.getManifest().version);
// expected output: "0.1"
