Good app, have been using it for 2+ years now, but seems this latest one for the FF Quantum 57, the plugin has left back something from the previous version.
I am not able to define the timezone name like it used to work for the previous version. This is very important for my work as I need to see the time differences as per the different time zone names and this makes it handy and accurate to do the conversions.
Like If I say PST gap to CST, it is not possible to do that now until I do it manually using some other method.
Also, the DST updates were automatic that way earlier, which is lacking now.

In the previous version, adding 'z' used to work with custom format, but there is no option in this latest version. Even if it is there, it does not do that thing. It just displays UTC there.

Pls add it back as soon as possible. This will be great.

Thanks a ton
