Browser Support • Re: [SOLVED] Protonmail overloading Pale Moon and the system

IIRC hardware acceleration is disabled by default in the Linux version of Pale Moon, so it's not surprising that you just found out it's turned off. I think you should still report it to Proton though; I don't think it should be normal for a webmail to use up a lot of resources for (I presume) rendering. What GPU is your system using?
