Good day! I've been having really strange and frustrating issues with YouTube just on my Windows 10 Desktop Firefox. I log into YouTube and when I click on my profile at the top right corner it does not give me full options. I cannot switch accounts, log out or get any of the top options just the bottom few. I have to clear cache and cookies in order to switch accounts or log out on YouTube. I cannot subscribe to any channels even though I am logged in. When I click the log in button so I can subscribe, it gives me Error 405 on Google. I also cannot watch any streams. The video loads and stops after 1 second. I feel like I've tried everything, I checked my adobe flash. Redownloaded it and made sure it is always enabled. Opened firefox in Safe Mode. I disabled all add-ons and themes, cleared history and changed cache and cookies settings from strict to standard. I refreshed firefox, then reinstalled it, but still nothing. I logged into YouTube on Edge and it works perfectly fine there so I have no idea what the problem is. Any suggestions for what I can do? Thank you.
