Hi again - I updated to 24.6 and the lettering on the tabs still doesn't retain its color when closing and re-opening Firefox. The domain colors are fine, the tabs always stay with black backgrounds for me with "." set as the domain. I've attached two screen shots: #1 shows my setting for the lettering on the tabs -- it's the yellow color for the lettering that is defaulting to black, but the setting still claims it's yellow when it's not. #2 shows my settings for the domain/background color which is working as I want it to and making all the backgrounds on my tabs black. I may very well be missing something so please let me know if so, thanks 🙂
