Using this add-on for years in Firfox and Thunderbird. It was most useful in thunderbird but unfortunately does not work there since firefox changed the plattform and foxclocks followed the changes. Now Thunderbird changed with version 68.+ to the new firefox add-on API. Hope it is possible to use FoxClock in the future again in thunderbird as well.

Es justo lo que buscaba. El panel está configurado para ocultarse, para aprovechar más la pantalla, y cuando estoy navegando me conviene saber la hora rápidamente

Very very awesome

Great Add-ons. Thanks.

Used for many years with no defects I can even recall.

Has been VERY helpful for international business meetings and social contacts as well!

Going to donate right now. HINT! ...

Exactly what I was looking for, simple yet useful.
