Some questions about RAM, BT and Firefox
I just don't know what else I can do. I compared Chromium and Firefox in html5test.com, got same result. All browsers says they doesn't support H.265. I turned off HW acceleration, nothing changes. I installed ffmpeg-libs and other codecs from Fedora wiki. Nothing changes. Videos are same vp9 in browsers. I spent all day googling but nothing helpful.

What are the actual security implications of port forwarding?
Detectify once made an offer of making free scans which I took them up on. There are plenty of free Content Security Policy (CSP) and other vulnerability checkers around such as Observatory or Pentest. Shields UP!! will identify which ports you have open.
