User interface is too smalll to read
This concerns Thunderbird 78...but the Support Loop may not have routed this question to the proper place.
Someone...PLEASE...there has to be a (simple) way to increase the font size of user interface elements (e-mail subjects, folder titles, etc.). Some of us simply CANNOT read these at their current sizes...and increasing the size of every element in Windows isn't the answer. Theme and Font Size Changer used to do the job, but no more...

Use the config editor to set a new value for layout.css.devPixelsPerPx, Right click the entry and select Modify, and set it to 1.25, OK to close Options.
That is one point two five. Just in case you missed that tiny dot. Setting it to 125 would bring something huge and totally unworkable and very difficult to correct.
