review Tor Browser environment variables (TOR_HIDE_UPDATE_CHECK_UI)

[Patrick]

Continuing the discussion from Disable TOR in TorBrowser 9:

@madaidan

@Patrick:

TOR_HIDE_UPDATE_CHECK_UI=1
TOR_NO_DISPLAY_NETWORK_SETTINGS=1
TOR_HIDE_BROWSER_LOGO=1
TOR_SKIP_CONTROLPORTTEST=1
TOR_SKIP_LAUNCH=1
TOR_TRANSPROXY=1

Only TOR_SKIP_LAUNCH=1 is needed to disable Tor. The rest aren’t really needed. TOR_HIDE_UPDATE_CHECK_UI=1 might be dangerous as it doesn’t alert the user of updates (I think) and TOR_TRANSPROXY=1 prevents the user from using any other proxy (e.g. if using a different socks port).

TOR_NO_DISPLAY_NETWORK_SETTINGS=1 might not do anything anymore as the onion button is gone.

remove 'export TOR_HIDE_UPDATE_CHECK_UI=1' for SecBrowser / i2pbrowser
