Safari Web Extensions: browser.webNavigation.getAllFrames by tabId return empty string url, when url is in blob protocol
Hello. Environment Safari version 18.1 (22B81). Problem In my Safari Web Extension i need to determine the url of the active tab. I do it this way: const onError = (error) => { console.error(error); }; const getFrameUrl = async (frames) => { console.info(frames) }; const getAllFrames = (frames) => { browser.webNavigation.getAllFrames({ tabId: frames[0].id }).then(getFrameUrl, onError); }; browser.tabs.onUpdated.addListener(() => { browser.tabs.query({ currentWindow: true, active: true }).then(getAllFrames, onError); }); The problem is that if the tab url is a link in the blob protocol, then the result function browser.webNavigation.getAllFrames({ tabId: tabs[0].id }) is as follows: {frameId: 0, parentFrameId: -1, url: "", errorOccurred: false} In Safari version 17 the correct URL value was returned: {frameId: 0, parentFrameId: -1, url: "blob://<some id>", errorOccurred: false} How can I fix the problem? Environment Safari version 18.1 (22B81).
