Restart/-load all active extensions in Firefox?

Question

Firefox's extensions leak memory and, with time, consume more and more CPU. This can be reset by disabling/enabling them. Is there a way to cycle all active extensions enabled status, without being forced to do it manually for each of them?

Here is a very crude JavaScript solution:

function clickToggleButtons() {
  // Static XPath to count the number of nodes
  var staticXPath = '/html/body/div/div[2]/div/addon-list/section[1]/addon-card/div/div/div/div/moz-toggle';

  // Evaluate the static XPath expression to get a node list
  var staticXPathResult = document.evaluate(staticXPath, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);

  // Count the number of nodes
  var numberOfNodes = staticXPathResult.snapshotLength;

  // Variable XPath to loop through nodes
  var baseXPath = '/html/body/div/div[2]/div/addon-list/section[1]/addon-card[%d]/div/div/div/div/moz-toggle';

  // Loop through each toggle button
  for (var i = 1; i <= numberOfNodes; i++) {
    // Construct the XPath for the current toggle button
    var currentXPath = baseXPath.replace('%d', i);

    // Select the toggle button using the constructed XPath
    var button = document.evaluate(currentXPath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;

    // Click the toggle button
    button.click();

    // Wait for 3 seconds before clicking it again
    setTimeout(function(currentButton) {
      return function() {
        currentButton.click();
      };
    }(button), 10000);
  }
}

// Call the function to start the process
clickToggleButtons();

Improvements are welcome!

Just open the web inspector, click Console, paste it and press enter. If you have a lot of extensions, it might take some time to reactivate them. It is not super stable so take note of all active extensions before running it, in case it fails to reactivate some of them so you can do it manually.
