1300856 - Reorganize about:performance so that it's clear which toggles belong to which displays

Status: RESOLVED WONTFIX

(Toolkit :: Performance Monitoring, defect)

Description

[Mike Conley (:mconley) (:⚙️)]

+++ This bug was initially created as a clone of Bug #1300850 +++

With dom.ipc.processCount > 1, and several tabs open, visit about:performance. Notice the table showing the memory usage of each content process and the parent process. This table was added in bug 1255843.

There are some checkboxes in about:performance. Namely, "Display only the latest 10s" and "Refresh automatically".

Neither of those checkboxes apply to the memory table, but the separation is definitely not clear. We should either make those checkboxes also apply to the memory table, or make them more visually distinct from the table so that it's clear that they don't involve one another.

about:performance is being redesigned; mass closing the bugs related to parts of the current about:performance page that we are not keeping.

Our goals with the redesign are to reduce the overhead caused by having the page opened, increase the reliability of the displayed information, and make the offered information actionable for most users. The back-end work is being tracked in bug 1419681.
