Hallo lenny2
Bitte mal testen:
Code
(function() {
if (!window.gBrowser)
return;
function viewMedia(event) {
let where = BrowserUtils.whereToOpenLink(event, false, false);
let referrerInfo = gContextMenu.contentData.referrerInfo;
let systemPrincipal = Services.scriptSecurityManager.getSystemPrincipal();
if (gContextMenu.onCanvas) {
gContextMenu._canvasToBlobURL(gContextMenu.targetIdentifier).then(function(blobURL) {
openTrustedLinkIn(blobURL, where = "tab", {
referrerInfo,
triggeringPrincipal: systemPrincipal,
});
}, Cu.reportError);
} else {
urlSecurityCheck(
gContextMenu.mediaURL,
gContextMenu.principal,
Ci.nsIScriptSecurityManager.DISALLOW_SCRIPT
);
openTrustedLinkIn(gContextMenu.mediaURL, where = "tab", {
referrerInfo,
forceAllowDataURI: true,
triggeringPrincipal: gContextMenu.principal,
csp: gContextMenu.csp,
});
}
}
let item = document.getElementById('context-viewimage');
item.setAttribute('oncommand', '(' + viewMedia.toString() + ')(event);');
item.label = 'Grafik anzeigen';
})();
