Bolding UI text is literally the best feature I've experienced in years (and I had to userChrome.css it into existence); If you have a 4k screen or use most themes you can barely read text and icons on the UI with ease. I don't know how this option does not exist as an accessibility option out-of-the-box. These UI accessibility features should be easily set in the Settings instead of hacking about:config and chrome/userChrome.css
You have no idea how good this looks and how easy it is to read the UI with bold text - especially on large glorious gorgeous 4k displays:
PS: Thanks for the work you do, Firefox is great!
