error launching web app: "tinyproxy was unable to connect to the remote web server"

Close for FF 6.0.4 and GG 7.0.0

The pull request was merged.

After taking alook to the WIP patch 

This is not the right solution... Though it points to the reason behind the proxy mess we have with tinyproxy launching several apps.
BlinkWebView inherits from WebViewBase, and there's the API we can set a profile to. We need to create a profile that we'll keep alive for each app and that's the one we will set the proxy to.

I think you need to make the helper keep a map of app ids to WebViewProfile. Then, when the BlinkWebView is created, it should check if there is a profile available for that app id, and set it to the webview. Looks to me a good place would be WebPageView::init, before the call to Initialize(). The profile would be destroyed in the WebPageView destructor, after d is destroyed, and not before, as it could cause a crash.

This issue is actually the one described in https://lf-automotivelinux.atlassian.net/browse/SPEC-1870?focusedCommentId=19152&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel

The white screen instead of the tinyproxy error is probably due to not having fixed https://lf-automotivelinux.atlassian.net/browse/SPEC-1889 at the time of reporting the issue.
