Well, I've found that I forgot to click the add button...
But now I have a new problem.
When I set the nation and the time zone and then click the add button, Is the city displayed below not be able to be modified?
though the time is correct but the city isn't the one I want to be showed.
Is it possible to make us be able to customize it?

Outstanding. Kudos.
One suggestion/request if I may:
There is an option to copy urls to clipboard,
why not an option to paste/open urls from clipboard?
(Surely, new line separated.)

I use it to create a pdf file from tabs. Its the best tool I found for that.

WOW! and again WOW!! This is an EXCELLENT extension! I like the feature which can "save Tab as PDF". This is so Awesome!! You did an EXCEPTIONAL job with this Addon Guys! Bravo!!! 👍 👏 ⭐⭐⭐⭐⭐

Excellent extension. It's very useful!

Very good extension ! But there is a little GUI bug: few days ago i think the extension was updated, and after that the icon is showing just the first 3 numbers of tabs. And yes, i have more than 999 tabs...

Many-in-one extension which does what it used to take several extensions, ..and does it remarkably well. Many thanks to the developer. Loads of useful tools.. Print PDF is as good as any other I have used; Copy URLs is pretty good; Multiple Timezone display on the icon ; Merge all windows ; Close duplicate tabs; Context menu...the list seems endless..!!

I was looking for a basic pdf converter function with no bells and whistles and FoxyTab elegantly fits the bill plus 1000% more easily accessible features with full freedom to customise. Their user support was pretty impressive too.

Всё классно!
