Scripts not working when using a reverse proxy

[mialeto]

Hi!

Thx for your scripts. I would really like to use them, but am unable.
According to the instructions, all that is needed to make the scripts work, is adapt the @match value to the address used by stash.
However when I activate the greasemonkey script stash only shows the spinning wheel and the Firefox console gives an "Error: Permission denied to access object".

Any ideas? Thx in advance
