Various parts of the Firefox UI look fuzzy. Not all of Firefox seems to affected: the menu for example looks extremely fuzzy, but the text of most webpages looks fine. After inspecting a screenshot, I've concluded that the problem is that Firefox disables ClearType sometimes. Please figure out what causes this and fix it so that ClearType is enabled everywhere.
(In case it matters, this computer uses Windows 10. The display resolution is 144 dots per inch. Firefox is the only program I regularly use that is affected. For example, in Notepad, Edge, Paint and qTox both the text and the menus look fine.)
