Font in toolbar and folder list and message list suddenly tiny

When I opened Thunderbird on my Mac this morning, the fonts in the sidebar with folders, as well as the list of emails and the toolbar were suddenly super tiny. My global fonts had all shrunk! The font in the open message window was also smaller than usual, but at least I could zoom in on that, but nothing worked on the rest. I've had the Theme Font & Size Changer for Thunderbird for quite awhile and all was fine, but it will no longer work. Why would it suddenly change overnight? This was before I updated Thunderbird to the latest for Mac, version 52.5.2. After updating, it still did not work. I love several of the other add-ons so I'd love to be able to stay with Thunderbird for my mail client. Any suggestions?

Sounds like you are another one using Theme and Font changer add on. It seems to have developed a problem lately.
