Still perfect in FF 4, with minor assistance Rated 5 out of 5 stars

QP's simplicity is its greatest asset. With help from the FIREFOX 4 UI FIXER extension the QP icon can be moved to the toolbar and does not require the add-on bar to be visible. Until QP natively supports this it's a great workaround.

For basic proxy on/off needs this cannot be beat. Thanks!
