Thanks for an amazing library. I wanted to try out the pagemirror extension, to find out more about the library works, but after following the installation instructions, it doesn't work. The tab that opens up immediately closes. Reproduced on different machines.
What happens is that the port that's opened by this line:
var port = chrome.tabs.connect(tabId);
Is immediately disconnected for some reason, which in turn closes the tab.
Does anyone know why this happens and how to fix it?
