Hi, I want the users to be able to update Firefox themselves. right now it says "Update failed. download the latest version" but when I do that that doesn't work either. I already unblocked https://aus3.mozilla.org and ^.*mozilla.*$, but that doesn't work. From where do the updates come from? Can I get the update.xml myself? The web filter we use is Websense Triton. https://aus3.mozilla.org/update/3/Firefox/33.0.2/20141027150301/WINNT_x86-msvc/en-US/release/Windows_NT/update.xml this URL doesn't work.
