The Chinese font in Firefox Android always looks very strange, and makes readers very uncomfortable. Please see the screenshot below, especially the characters I highlighted -- I think all Chinese readers understand what I'm saying, and the characters 关 and 复 even has only 1/2 width of normal. Really weird. Some characters looks somewhat like Japanese font. From '''about:config''', I find the font's name is ROBOTO, which is a western character font designed by a Google staff, and doesn't cover Chinese character. So I have no idea where the font shown comes from. Firefox android seems to be the only browser that has such problem. In old versions, we can change the font with the Stylish addon, but there's no such addon in recent new version. As a Chinese user, I almost can't tolerate this problem anymore. In my opinion, the solution is very simple: just use the system font of Android, which is enough. Hope the developers take this problem into account.
