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

In some situations, the Onewire temperature sensor does not give values when over 70 degrees celsius. To solve this, edit /config/onewire.ini and add the line: presence_pulse_delay=50 Under the [general] section. Save and reboot, and it should work. The default presence pulse delay is 35 uS.
