Recently I've run into a strange problem logging into the MaplePrimes site.  I have two computers, both running Debian linux.  On one, I can login in using the FireFox browser.  On the other I cannot.  It accepts the password, but immediately reopens the window that prompts for a password.  If, however, I switch to the chrome browser on that machine, I can then login.  Any idea why Firefox (aka IceWeasel, on Debian) would have an issue?  Have I configured something strangely?...

The Standard GUI has an option (Tools -> Options -> General -> Browser) for configuring an installed web browser.  The GUI uses that for its own purposes (for example, clicking on an error message opens the browser at a related Maplesoft site).  Is it possible for the user to access the configured web browser from within Maple, using Maple code?

How can the ?DifferentialGeometry package be used to apply a vector (derivative) to a scalar?  I thought Hook might be used here, but I don't know that there is a way to express a scalar as a 0-form.  Consider

with(DifferentialGeometry):
DGsetup([x,y],E2):
Hook(D_x, x^2);
Error, (in DifferentialGeometry:-Hook) expected 2nd argument to be a differential form or bi-form. Received x^2

Occasionally I want to restrict a search of MaplePrimes to posts from a specific user.  Is that possible?

How do I insert a hyperlink with this new site?  The link icon on the toolbar is grayed-out.
