The horizontal scrollbar is hidden by this CSS rule: https://searchfox.org/mozilla-central/rev/3160ddc1f0ab55d230c595366662c62950e5c785/toolkit/components/aboutperformance/content/aboutPerformance.xhtml#62

I did this in bug 1502951 where I couldn't come up with a perfect fix. I explained in bug 1502951 comment 16.

Mass closing about:performance bugs as about:performance has been removed in bug 1836191 in favor of about:processes which displays more accurate data. If this bug still applies to about:processes, feel free to reopen and change the summary.
