Missing arrow buttons for scrolling in Thunderbird and Firefox

I am currently running Ubuntu 15.04. I previously had Thunderbird and Firefox installed on Ubuntu 12.04 and everything was fine then. With the newer version, however, scrolling is very erratic and the arrow buttons have been removed. This is extremely annoying because it is impossible to scroll through the list of messages without skipping too far. Why has no one come up with a solution for this yet? This has been an ongoing problem for a lot of users for several years now. Is it possible to reverse this "upgrade" and go back to where the arrow buttons actually worked?

Does the same thing happen in safe mode (Help/Restart with Add-ons Disabled)?

I've had a few controls missing from Thunderbird for some time. I learned from various comments that this was likely to be due to an older version of gtk3. In my case, I was without some checkboxes and radio buttons in menus and submenus.

I was stumped because no-where could I find any guidance on how a user could upgrade or even influence the precise version of gtk3 in use.

In setting up a new Linux computer, I was faced with warnings that certain desktop themes wouldn't appear properly because particular libraries were missing. So I went looking for fixes for this and in doing so I came across some themes that mentioned gtk3. I installed one of these (Clearlooks Phênix) and my missing tools came back.

This is MX Linux 16.1 with the Mate desktop environment, and I appreciate that Ubuntu is something different, but I hope these comments might help you and others.
