Ever since yesterday, when I try to access Google or Youtube or Google Images, sometimes the page won't load and it will say that secure connection failed and display the following message:
SSL_ERROR_RX_MALFORMED_SERVER_HELLO
It has only happened few times so far and whenever I hit F5 the page just loads normally, but I'm still concerned. I tried to look for solutions online but every topic was Windows specific. Is there something wrong?

Are you using Firefox? This appears to be a FF bug:
Be aware that this can also be caused by something getting in the way of your traffic, either good-natured things like intrusion prevention systems or bad things like malware.
Set security.tls.version.max = 3 in about:config
3 will use TLS 1.2
4 will use TLS 1.3
