Hi, I have HP PRO BOOK 6461B. When I try the Mozilla browser downloading from my laptop. He shows me errors. You are not allowed for this browser. Anyone can explain or solve these errors. Thanks! Vickey Hat

I'm guessing his laptop uses Windows 10 ? and you are actually trying to install desktop Firefox web browser from say www.mozilla.org/firefox/all/ ?

This Hubs section you posted this thread in is about 3D virtual spaces and is not a web browser as you can see at https://hubs.mozilla.com/

Since you are likely referring to the web browser Mozilla Firefox or Firefox for short I am going to move thread to Firefox section.

Check the settings in your security software to see if there is a setting that may be blocking downloads. To diagnose whether Internet security software is causing problems, you can try temporarily disabling it, seeing if downloads work, and then re-enabling the software
