ProtonMail, StartMail... even OrionFeedback has just randomly refreshed for me while I was scrolling the page to the bottom 😄
The worst part is that it might refresh during the payment process or other sensitive operation (it actually happened for me during ProtonMail payment, and in the end payment went through but Proton did not upgrade because the page has been refreshed in the "bad luck" momen 😅).
Is some kind of a memory leak causing this? It makes the browser completely unreliable...
