Hi x-lksk, thank you for the bug report. 🎀
I will try to reproduce it and see if I can do anything about it.
Until then, I guess, the only way is to try with another browser.
Using Linux, specifically an unusual version known as Puppy Linux, whose main thing is being so lightweight it can be run entirely from RAM, and thus does not always have certain things you'd expect to come pre-packaged with an operating system. Maybe it has something to do with how much memory it is trying to use at once? Or trying to save data to somewhere that simply does not exist on this computer?
