Firefox doesn't load YouTube sidebar
Yesterday I completely formatted my computer and when I tried opening Firefox today, I got the "sec_error_unknown_issuer" error. This is not the first time that happens, last time I formatted my PC I also got the same problem, and I fixed it by disabling Enterprise Roots in about:config. But whenever I try opening YouTube, the website it's completely ruined, the sidebar (where my subscriptions and playlist are located) doesn't load and neither does the videos from the bottom. Last time this happened, I completely gave up and switched to other browser, some months later without touching anything, I opened Firefox again and somehow it was loading the sidebar. But this time I dont want to wait again, and I don't know if it will "fix" by itself. I tried opening Firefox in safe mode and everything, and had no success.

I think I solved it. Apparently, I had to disable the proxys on Youtube!

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

I had no success. I only use Windows Defender, so it's not an anti-virus problem. I disabled Hardware Acceleration already and it didn't worked. Youtube is completely broken, I can't watch videos or use any feature. Meanwhile when I test on Edge it does. It's a browser problem it seems
Can you try Windows in Safe Mode?
