Can you please try viewing your proxy settings (System Preferences > Network > Advanced > proxies) and then run Jaksta, which should then result in the Web Proxy (HTTP) and Secure Web Proxy (HTTPS) proxies being turned ON.
Then quit Jaksta and note whether the proxies turn OFF or if stay ON. They should become unticked automatically, but if they stay ON then there is a chance that is what's breaking Chrome (and likely your other browsers). Based on what you're describing this is not likely the case, but it's good to check and be sure.
In the Chrome settings there is only an option to use the computers proxy settings, and you cannot configure specific proxy settings in and for Chrome. This is to say that Chrome should be doing whatever the computer is doing.
It would be very odd if it is only affecting one Google account, or even if it is just the active Chrome window. It might be that there is some disconnect, lag or settings caching between Chrome and the system settings that is creating a conflict. This would be a new scenario that we have not encountered before, so it might be hard to troubleshoot.
Please let me know how you go.
