Lately Firefox has become unbearably slow. I checked my Verizon connection. Their test showed I have good network response. I get these long TLS handshake messages. I tried refreshing Firefox. I lost my adblock then reinstalled it. It seems to be working but I no longer see the icon showing how many ads are blocked. I thought I might try customizing it but when I go into Settings-Add-ons I can't even find it. By the way I can't find what release I'm on either but it should be the latest.
