This question was asked 2 years ago and answered successfully back then (Can I use TOR browser without using TOR network?), but the Tor Browser has changed since then and these old instructions are no longer fully sufficient for the current release of TB. The problem is that TB resets a few of these modified settings each time it starts so that you have to re-enter these settings over and over. It does work once you make these manual changes, but they are lost on re-start. Any solutions to make these settings permanent or otherwise achieve using the TB without the Tor network?
- Go to Tor Browser → Alt+T → Options → Scroll to the bottom and under "Network Proxy" select Settings → "No Proxy".
- Go to about:config in address bar → search for
network.proxy.socks_remote_dns→ set value to false (by double clicking) → search for
extensions.torlauncher.start_tor→ set value to false (by double clicking).
- Go to about:addons in address bar → disable Torbutton and TorLauncher by clicking on the Disable button.
Changes will persist during restarts.
Other options are: install Firefox and the addons HTTPS Everywhere and NoScript or uMatrix. Go to about:preferences#privacy in the address bar and under Cookies and Site Data select Keep until: Firefox is closed and Accept Cookies: Never.
