Frequently Asked Questions


FoxClocks shows the wrong time. What can I do?

FoxClocks retrieves GMT/UTC from your Operating System. If this time is incorrect, FoxClocks will not work properly until you correct your system time/time zone settings (this may even involve updating your OS). You can check that your system is reporting GMT correctly by temporarily adding the ‘GMT/UTC” time from your Zone Picker. That time should agree with

Retrieving time… – according to this server, foxclocks.org

Note that your system may be incorrectly reporting GMT even if the system clock shows the correct local time.

If you’re still having problems, make sure that you are running the latest version of FoxClocks, and that your time zone database is up-to-date. If you’re still having problems, see this FAQ.

Why can’t I find my city or town in the Zone Picker?

The Zone Picker covers all the world’s time zones by country and region, and contains a large number of major cities, but not all.

For Google Chrome and Firefox Quantum you should be able to find your city or town using the Search Cities box. For If this doesn’t work, or you’re using Thunderbird or an older version of Firefox, browse the Zone Picker by country and region, rather than city. Remember that you can re-name the zone after you’ve added it.

Can FoxClocks synchronize my computer’s time with a remote server/atomic clock?

No – modifying the sytem time is a privileged operation best left to the operating system. All modern OSs have an automated mechanism for synchronizing their time with a remote computer using a sophisticated protocol called NTP.

How do I uninstall FoxClocks?

Follow the instructions here for Google Chrome, here for Firefox, and here for Thunderbird.

FoxClocks really has gone wrong. What can I do?

You have the latest version of FoxClocks, none of the above FAQs apply, and there’s still a problem. In this case, you should consider resetting all Foxclocks settings to their default values. To do this for Google Chrome and Firefox Quantum, simply uninstall and re-install the extension. For Thunderbird and older versions of Firefox, re-installing will NOT reset your settings. Instead:

  • Go to the special URL about:config
  • Enter ‘foxclocks’ (without quotes) in the Filter box towards the top of the window
  • Right-click on each bolded entry below the Filter box and select ‘Reset’
