Hi, i think the main problem is that via java/javacript the browser can do direct connections, bypassing your proxy and only using your default gateway! You can see this bypassing with test sites like https://www.jondos.de/de/anontest .
That's why i am not using a default gateway on the PC i am using and usually you only need proxy and no default gateway (behind the Router with the firewall and proxy). For some situations like updating my homepage via ssh/rsync i'm using a default gateway but only for a short time (approx. 1 minute) and at that time i'm using no browser.
