This is a most excellent place for technology news and articles.
This is definitely not normal, Firefox never freezes for me. May be worth checking that out, especially your extensions.
Especially your security programs, like third-party antivirus or firewalls. They can install system-level plugins in your browsers, and sometimes those don't work well. Windows defender and the built in firewall are good enough and play nice with other programs.
