Allow all this window

Instead, just Allow Scripts Globally (dangerous) and stay off the porn and warez sites while you're looking for a site. If any of your flight info sites have been hacked with a zero-day exploit, then it's game-over anyhow. Personally, whenever I want to Allow Scripts Globally (dangerous), I restart Firefox in Sandboxie and delete the sandbox before starting a new session.
