What is the best way to set up a command that will run when the firefox-addon is being uninstalled?

I recently developed a Firefox add-on using the Add-on SDK.

The functionality of my script in Firefox is irrelevant in this context. However, I am seeking guidance on how to implement a function that triggers upon uninstall and disabling.

Although I have reviewed this Code Samples article, this resource, this documentation, and this manual along with this helpful answer, I am still struggling to successfully execute the desired command during uninstallation.

Furthermore, it appears that the provided manual may be outdated based on the warnings I received when compiling using:

cfx xpi

To address these warnings, I replaced the usage of the Components Object with const {Cu} = require("chrome");. Despite making this adjustment and successfully compiling the code, I have yet to achieve the execution of a command during uninstallation.

Should I consolidate all the necessary code within the main.js file? Or do I require a separate uninstall file for triggering this function?

If possible, could you please provide a concrete example demonstrating how to approach this implementation effectively?

Answer №1

Within the file main.js, implement the exports.onUnload method.

Here is how you can structure it in main.js:

exports.onUnload = function(reason) {
    // This function is executed when the add-on is
    //     uninstalled
    //     disabled
    //     shutdown
    //     upgraded
    //     downgraded
};
