1510127 - Difficult to get a quick overview of memory usages because of different units and decimals

Status: UNCONFIRMED

(Toolkit :: Performance Monitoring, defect)

Description

[Bruce]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

Open about:performance to get a quick overview of which tab/add-on is consuming more memory.


Actual results:

1. Some memory usages are in MB while others are in KB
2. Some are reported with a decimal, others aren't

This means that values that "look" longer aren't necessarily big. E.g. `778 KB` appears longer than `4 MB` but is actually smaller.


Expected results:

Both Windows Task Manager and Chrome's handle this a bit better, I think:
1. Windows Task Manager reports everything in MB, rounded off to the first decimal place
2. Chrome's Task Manager reports everything in KB, with no decimal places

Bug 1498187 will help here but will require sorting by memory column. I would prefer to retain the `Energy Impact` sorting but still get an overview of relative memory usages.
