Well in Chrome you can't hook into the network layer to record/replay requests like I've done here (you could fake it by overriding the ServiceWorker, possibly, but this feels brittle and I'm not sure if it's possible either). I'm not familiar with Firefox extensions but I'm given to understand you likely could implement this project as a Firefox extension. Locking down Electron apps to be safe on the larger web is certainly one area where I think electron could do a lot better. I think my project has followed all of the recommendations and should be safe, but I agree with you that it feels like a bigger attack surface. I personally wanted it to support offline browsing of documentation sites, which are generally pretty "safe" from that perspective.
