[Optimoz] "getReferrer is not defined" error for several gestures

[Gonzalo HIGUERA DÍAZ]

Hello.

I have recently upgraded to Firefox 1.5 beta 1 under Windows XP SP2,
which has led me to install the latest Mouse Gestures extension. I
have found that several motions (duplicate tab/window, open in new
tab/window, ...) do not work. I get a popup screen telling me that
"getReferrer is not defined".

I erased my profile (correclty, I hope) and tried installing Mouse
Gestures again, to no avail. Does anybody suffer similar problems, or
has anyone got some advice?

Thank you.
