After switching back to Firefox a few months ago, I started having a problem with itch.io: the dashboard graphs were only loading sometimes, and then half the time they looked squished. The reason remained a mystery until today.

Turns out the cause was the NoScript extension, that I've been using happily for many years in the past. New versions cause performance issues, and (as it turns out) weird bugs like this one.

If you're also experiencing weird stuff on itch.io while using Firefox, this might be the cause. Consider switching to uBlock Origin Lite.
