Change Web Browser DPI

If you’re a noob like me who wants more to be displayed on a screen, and find the stock web browser needs a DPI increase, you can achieve this by entering about:config into the address bar, accept the warning, search for layout.css.devPixelsPerPx and change it to a smaller value - I went to 2.25 (it was originally 3) - and finally swipe to accept the change.

Info thanks to: Firefox/Tweaks - ArchWiki

I also changed stock UI DPI using this method: UI-Themer missing from OpenRepos - #63 by deprecated - I reduced it to 1.5

For reference, my device is an XZ2
