FoxClocks has been updated

Please help support FoxClocks updates!

FoxClocks 5.1.3 for Chrome and Firefox (April 3rd, 2018)

This version of FoxClocks starts up faster, fixes a number of bugs, and adds support for Opera and Microsoft Edge (note that we haven’t released FoxClocks on these platforms yet). We’ve also updated the time zone database.

Internally FoxClocks now uses secure (https) URLs wherever possible – and, but not, which is used for search functionality, but doesn’t support secure communication. Bug fixes:

  • Fix clocks not being created in statusbar for some slow-loading web-pages
  • Pick up global time format change instantly, not waiting till next clock tick
  • Handle body element not existing when calculating where to put time zone details popup

We’ve also made some boring internal technical changes including switching the entire codebase to ES6/ES0215 (including hooks for modules as soon as there is full browser support). We’ve also removed support for legacy Mozilla extension settings.


Welcome to the new FoxClocks, nothing like the old FoxClocks!

This version took weeks of development – please consider donating by clicking the friendly yellow button above!

With Firefox Quantum, ‘legacy’ extensions such as the original FoxClocks no longer run, and new-style extensions are much more limited in their ability to modify the browser; they can’t, for example, create or add to a statusbar or toolbar. We’ve added a simulated FoxClocks statusbar, but are aware that it can occasionally interfere with web pages – you can close the statusbar on any page, or disable it entirely from the options.

Thanks for your understanding.
