Hi, I noticed the fontsize of the `mainline` Thunderbird 102.12.0 is quite different (very much too small) on KDE Plasma 5.27.5 since my upgrade to Debian Bookworm. Basically the machine is a default Debian Bookworm installation. Changing the `layout.css.devPixelsPerPx` value didn't result in the expected behavior. Interestingly `mainline` Firefox / GTK based / Qt based applications are not affected and the problem (too small fontsize) is only there for Thunderbird.

I managed to find a workaround setting ``` GDK_DPI_SCALE=1.2 GDK_SCALE=1 ``` only for thunderbird e.g. by invoking it via ``` GDK_DPI_SCALE=1.2 GDK_SCALE=1 thunderbird ``` in the `.desktop` file.

Did you try using the user interface font setting in the view menu before trying to hack setting in the user preferences file. Using the user interface is more likely to give you a lasting or workable result than hacking, although Linux can need more hacking that other operating systems because nothing is "standard" even between distributions.

Matt, thank you so much. You don't want to know how long I browsed through the `Settings` menu for that feature. That hint helped.
