Hi, I am developing the Click & Read web add-on for Chromium, Firefox and Safari. We use xcrun safari-web-extension-converter tool to generate the Safari add-on. The build on Xcode had no meaning errors/warnings, until we had to switch to a more up-to-date MacBook (required as deprecated Mac had no support for latest macOS and thus for Xcode compatibility !). So now I build my add-on on an Apple M1 MB Air on Sequoia 15.0 with latest Xcode, but I encounter an error ? or warning ? : NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed Unable to create bundle at URL ((null)): normalized URL null Unable to create bundle at URL ((null)): normalized URL null Unable to create bundle at URL ((null)): normalized URL null But it doesn't prevent the add-on build to complete as I am able to open it onto Safari. Then, when loading the add-on on a test web page, I get this error on safari console: Error: Invalid call to runtime.connect(). No runtime.onConnect listeners found. BTW, the same add-on Dist works as expected on Chrome or Firefox (on macOS). So it seems the runtime listener runtime.onConnect.addListener isn't initiated on Background script... Thanks for your feedback and help

Hi, I am developing the Click & Read web add-on for Chromium, Firefox and Safari. We use xcrun safari-web-extension-converter tool to generate the Safari add-on, with up-to-date MacBook MacOS, Xcode et Safari : Sequoia 15.3.2, Safari Version 18.3.1 (20620.2.4.11.6), XCode Version 16.0 (16A242d). We have updated our addon to Manifest v3, having the Background script as Server Worker "background": { "service_worker": "background.js", "type": "module" } self.addEventListener("activate", (event) => { console.info("Service Worker activated", event); event.waitUntil( self.registration.pushManager .subscribe({ userVisibleOnly: true, applicationServerKey: urlBase64ToUint8Array( process.env.VAPID_PUBLIC_KEY ), }) .then(async (subscription) => { console.info("[Service Worker] Extension is subscribed to push"); const { subscription: savedSubscription } = await getLocalStorageKeyData("subscription"); if (savedSubscription) fetchApi({ url: `${API_SERVER_URL}/subscription/remove/${savedSubscription.keys.auth}`, }); // Remove previous subscription from server on addon activate currentBrowser.storage.local.set({ subscription: subscription.toJSON(), }); // Save subscription in local storage currentBrowser.runtime.setUninstallURL( `${API_SERVER_URL}/subscription/remove/${ subscription.toJSON().keys.auth }` ); // Set uninstall URL to remove notification subscription on addon uninstall fetchApi({ url: `${API_SERVER_URL}/subscription`, reqInit: { body: JSON.stringify(subscription.toJSON()), method: "POST", headers: { "Content-Type": "application/json", }, }, }); }) .catch((error) => { console.error("Push subscribe error: ", error); }) // Subscribe to push notifications ); }); When trying to subscribe the addon instance to our Push server, we get this error : Push subscribe error: NotAllowedError: User denied push permission Our NodeJS backend is using the web-push librabry : https://github.com/web-push-libs/web-push) to save subscriptions and make notifications push. By looking for same errors on forums, the best hint I found is that it could be related to the testing is done on localhost (addon is built from XCode onto Safari, and Push server is running on localhost). Thanks for your help !

Hi, after upgrading MacOS (MB Air M1 Version 26.2 (25C56)) & Safari (Version 26.2 (21623.1.14.11.9)) to latest versions, we are experiencing a new bug occurring with our web extension (Click & Read) on local storage writing and getting this error : Invalid call to browser.storage.local.set(). Disk I/O error. This doesn't happen on other browsers (chromium, Firefox). export const setLocalStorage = async (value: object) => { try { await browser.storage.local.set(value); } catch (error) { console.error("[Click & Read] Error setting local storage", error); } };
