Scrollbars and up/down buttons
I've just upgraded from Thunderbird 52 on Windows to 91.6.1 on Linux. Everything works great - except the scrollbars.
The default scrollbars were quite narrow - I got that fixed by changing some of the scrollbar settings. But the most important functionality is still missing.
The first bit is the up/down arrows/buttons. I enabled the setting "widget.non-native-theme.gtk.scrollbar.allow-buttons", but that's not enough to make the buttons appear it seems.
The second bit is what happens when you click above or below the slider. On Windows/TB52 you would move one "page" up or down. On Linux/TB91 you move to the part of the list you click on. This would be fine, for a folder of 20-30 messages. But in folders with thousands of messages I really miss the functionality of old Thunderbird.
Is it possible to enable practical scrollbars in modern Thunderbird?
