Folks help! How do I turn off or modify this brand new High Contrast bold font in Thunderbird 78.4 that just automatically updated? Especially the left preview nav window but basically all of it? The font and contrast and boldness hurt my eyes so bad I can't look at Thunderbird for very long and am getting nauseous. Seriously. Never had software do this to me before on my Mac. Have tried choosing different 'themes' under preferences but each one is as annoying as the next. Have tried changing the font and the font size but that isn't getting rid of the new boldness or the contrast. Even tried restarting THunderbird twice (but no I haven't tried re-booting my MacBookPro, no) Help! Have been a Thunderbird user and donor for prob 15 yrs now, and this is the most extreme makeover of the UI yet, seems like an awfullot of unneeded changes shoved on us. Why couldn't these things be options and features that are manually turned on and selected at each upgrade by the user instead of a wholesale change across the platform?
