Hello The 'new' Thunderbird installed itself on my PC yesterday BUT the list of messages has become hard to read as a result. I can't quite tell why this is - it might be the typeface has changed or the font size has decreased by default. The whole page seems less clear. This must be a universal change as I noticed it on my business account on a different PC as well. I tried to resolve it myself, I went into 'settings' and altered the typeface & size but couldn't see what I needed to do to 'save' my changes. Can you tell me please how to 'save' the changes I tried? OR How I can go back to the previous appearance? I'm sorry I can't show how it looked before to show a proper comparison or explain the difference in more detail but it IS different. Thank you for any advice you can offer.
