Any idea why the connector in Vivaldi (Chromium based) is limited compared to the one in Chromium itself? The three "Save to Zotero as..." options are not visible in Vivaldi while the main connector saves the item perfectly from Vivaldi to Zotero. (MacOS 10.12.6, Vivaldi 1.13, Zotero Connector 5.0.24.) The Connector's advanced tab for reporting errors shows this entry:
[JavaScript Error: "TypeError: Cannot read property 'substr' of null at Zotero.Proxy.toProxy (chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/proxy.js:787:21) at _showProxyContextMenuItems (chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/background.js:622:24) at _updateExtensionUI (chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/background.js:450:4) at Object.onTabActivated (chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/background.js:179:3) at chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/background.js:741:29 at "]

Thanks for looking into this.
