Details

[Affected versions]:
Firefox 65.0b4 (BuildId:20181211223337).
Firefox 66.0a1 (BuildId:20181212215507).

[Affected platforms]:
Windows 10 64bit
macOS 10.14
Ubuntu 16.04 64bit

[Steps to reproduce]:
1. Launch Firefox.
2. Access the about:performance page.
3. Resize the Firefox window.

[Expected result]:
A horizontal scrollbar is displayed. 

[Actual result]:
Resizing the Firefox window doesn't trigger a horizontal scrollbar and the users have to resize the Firefox window back in order to see the "hidden" about:performance information.

[Regression range]:
This is not a regression.
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.
