There's no flag for Ukraine for whatever reason

Error update time zone database!

I gave this Addon a 4 out of 5, why? Because it hasn't been updated for over 4 years as of this Review. I still think the overall idea of it is superior, but im pretty sure it can be further developed for new features, and optimazation.

очень удобно смотреть время, когда ты часто в дороге

Firefox is the best browser, i like it so much

For Paris France, the clock does not take into account summer time, so it is one hour off.

Useful as this extension is, I find that it integrates poorly with the layout of most websites no matter which screen location you choose. It also interferes with the loading of some websites, seemingly at random, including the student access websites for my college, and many artist's storenvy shops sites, and seems to have no easily accessible bug reporting.

Works great!
