[fr] Allow "Go back" to work in unique case

[ttbuddy]

Is it possible to make it work in this scenario:
Include pattern: chrome-extension://cjpalhdlnbpafiamejdnhcphjbkeiagm/document-blocked.html?details=*
Redirect to: javascript:window.history.back();
Pattern type: Wildcard

Good question. I don't think this is possible because AFAIK an extension cannot redirect a chrome-extension URL to another page or resource. (Well, technically, it should be possible in Firefox, but it would require the user to enable certain hidden preferences that would reduce their browser's security. I'm not sure if that flexibility is possible in Chromium-based browsers at all.)
