Torbutton WARN: no SOCKS credentials found for current document.

This warning appears in the log quite often. It might be benign and can probably be downgraded to INFO or DEBUG.

Torbutton WARN: no SOCKS credentials found for current document.

I can trigger this message setting app.update.log to true in about:config and opening the noscript settings.

found this also in legacy/trac#27828 (moved), legacy/trac#27221 (moved), legacy/trac#26579 (moved), legacy/trac#25946 (moved), legacy/trac#24654 (moved), legacy/trac#24263 (moved), legacy/trac#20195 (moved), legacy/trac#18138 (moved)
