Browser Support • Re: Why is Pale Moon so slow?

And strangely, after visiting some slow sites and closing the corresponding tab, PM stays slow and needs a File -> Restart...

That's the one thing me do nnot understand why this behaviour. It happens every time visting twitter/x. Only restart brings help, also this occurs with Basilisk. Dactyloidae not fully tested, while it seems to be a little better, only the heavy-js tab, like twitter/x, seems to slow down. Which may be no wonder, Dactyloidae has more instances open, what can bee seen in taskmanager.
