The "World Clock Time" add-on allows you to create a browser tool bar pop-up that displays world clocks.
Simply choose as many clocks as you wish from the drop-down menu in the pop-up. Please keep in mind that at this time, there are a maximum of 34 options to select from. You can also set the daylight-saving value before adding any item (i.e. -1, 0, and +1). The toolbar popup may be dragged around; all changes will be automatically saved to memory. By default, 9 items are added to the toolbar popup; however, they can be removed at any moment by clicking on the cross sign next to each one (remove button at the top-right corner).
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
