does anyone know how to change the language of the GUI of Thunderbird 60? It comes up in my system's language but I would like to have it in English.

I used to use an add-on called Locale Switcher but that is not compatible with the new TB anymore. Any ideas?

I don't have Thunderbird 60, but I'd guess that you'd use the config editor. To get there, use Edit->Preferences->Advanced->General and click on the button for the config editor. If this is the first time you've done this, you'll get a pop-up asking you to confirm that you know what you're doing. Once you're in, search for locale and see if anything interesting shows up. HTH, HAND.

Yep, that's what it was. I searched for general.useragent.locale which was the name of the string before, couldn't find it. Then I found intl.locale.requested and set a value but it didn't work. Upon a second try, it finally worked. Must have misspelled it or so.

OK, figured it out.

Go to Preferences --> Advanced --> General --> Config Editor:

Set intl.locale.requested to your desired language. In my case that's en_US.UTF-8.

Then restart Thunderbird.
