I upgraded to Firefox 5 today and since then the only script I use stopped working. I uninstalled it and tried to install it again, but when I click on "Install" in
userscripts.org, the page opens as text. I cannot install any script at all (I tried a few more after that just to be sure, that there's not a problem with this particular script I'm using).
(When I check the add-ons page, I see many java consoles and more than 1 java add-on, and I'm sure that wasn't like that before.)
