Sometimes issues crop up, and we list them here with their solutions

FireFox recently changed automatic detection of touchscreens when they released v52.0. This affects the hover values because FireFox won't show the hover values if it thinks a touchscreen is being used. To make a long story short, changing this configuration value fixes the problems on systems where FireFox thinks a touchscreen is enabled:

• about:config
• Search “dom.w3c_touch_events.enabled”
• Modify value 2 → 0
