Can't install themes and extensions :(
Hi there!
My latest portable Thunderbird has a big problem. I cannot install any theme or extension. I use Windows XP Pro SP2, but it happens on all computers I have, even in Linux one, using the profile I use in windows. If I drag & drop, or click install and select xpi or jar file, the theme/extension window remains blank... what can be causing this?
Any idea?
Thanks for your time.
