Also need help with this
I also need help now through Firefox need to setup a new WiFi network and password. I guess I need someone to help me with everything. This hacker destroyed everything. I had to buy a new laptop I have to set up ASAP my college courses started yesterday please I’m begging for help
That isn't something that can be of helped here. If you bought a new wifi there are instructions that come with it how to do the setup through which browser you use including firefox.
