I love this add-on but, recently, I encounter a strange behavior: when I select a site I am subscribed to in a PocketTube folder, PocketTube shows me the "Videos" page of the channel which is then constantly refreshing/flashing (or jumping to the next page?) until it shows me a blank page (the last page?). When I click on the "Home" tab of the channel, this behavior stops. It seems to only happen on the "Videos" tab.

I use the latest version of Firefox on Windows 10.
This behavior disppears if I switch off PocketTube. Cheers

EDIT: thanks for your reply. Spot on, I must have disabled it by error. Thanks! I updated to 5 star!
