Desktop and laptop with Win10 here. I use FireFox routinely while my hubby uses Chrome.
I sometimes use a service that has to run through a proxy server, but don't like the idea of internet banking details etc passing through their hands. It seemed obvious to configure IE/Edge to use the proxy, but found that Chrome "inherits" proxy settings from IE.
I downloaded Vivaldi browser and gave that a try, but it too caused Chrome to adopt the proxy server settings.
Is there a browser out there that uses truly independent settings, apart from FireFox, or am I being too paranoid in he first place?
As burn it says, the browsers aren't 'sharing' your proxy information with each other, but when you set one up to use a proxy, those settings are stored in windows network settings rather than in the browser itself since the browsers pass their traffic through Windows networking rather than straight out so that's where the information must be stored. Tor browser may well work, and I also believe there are third party programs that allow more specific proxy control so have a look around for those if tor doesn't work, or if you want to keep using chrome and ff. I remember one called Proxy Switchy! but I don't know whether it's still going.
