1195918 - Frame Load Interrupted error when we ask user to open external app

Status: RESOLVED FIXED

(Firefox for iOS :: General, defect)

Steps to reproduce:

* Log in to twitter
* In the banner that they show, click the 'Install' button to get redirected to the app store

Notice that we ask the user to open the app store link. I think that is good. But, the original page also changes to a 'Frame load interrupted' error page. That is not good.

Ignore the "Frame load interrupted" error that is triggered when we cancel a request to open an external application and hand it over to `UIApplication.openURL()`.

The result will be that we switch to the external app, for example the app store, while keeping the original web page in the tab instead of replacing it with an error page.
