The intended method of using a non-default browser is well documented and the
OP did exactly the right thing. However, even if Opera is present, the 'right

Hello. This tracker is used to report bugs and file feature requests for
Python itself, not request help (mailing list such as
http://mail.python.org/pipermail/python-list/ are appropriate venues to ask for
for help). I’m changing your question to a bug report
