[solution may no longer be the case, read comment]
runtime.onInstalled
is not triggered if you disable/enable your extension.
My solution is to always add menu items and swallow errors:
'use strict';
{
let seqId = 0;
const createMenuLinkEntry = (title, tab2url) => {
const id = (++seqId).toString();
chrome.contextMenus.create({
id: id,
title: title,
contexts: ['browser_action'],
}, () => {
const err = chrome.runtime.lastError;
if(err) {
console.warn('Context menu error ignored:', err);
}
});
};
createMenuLinkEntry('Go to Google', (tab) => 'https://google.com');
createMenuLinkEntry('Go to GitHub', (tab) => 'https://github.com');
} // namespace
