The popup's document is reloaded each time it is opened, so it loses any state it had.
If you want to save data permanently (i.e. across Firefox restarts) use the storage API. The favourite-colour add-on gives you an example of this.
If you only need to save state across popup-openings, you could perhaps set the state in the background page using runtime.getBackgroundPage, doing something like this:
chrome.runtime.getBackgroundPage((page) => {
if (page.popupContent) {
document.querySelector("#content").value = page.popupContent;
}
});
function setState() {
console.log(document.querySelector("#content").value);
chrome.runtime.getBackgroundPage((page) => {
page.popupContent = document.querySelector("#content").value;
});
}
document.querySelector("#content").addEventListener("keyup", setState, false);
Note that you do need to have included a background script in your add-on for this to work. Also I'm not sure whether listening to keyup is the best idea, but it does seem to work.
