1519108 - Closed tabs will not disappear immediately from about:performance list

Status: RESOLVED WONTFIX

(Toolkit :: Performance Monitoring, defect)

Description

[Vlad Lucaci, Thunderbird QA (:vlucaci)]

Attachment: Process not synced .gif

Affected versions

• 66.0a1 (2019-01-10)
• 65.0b9 (64-bit)

Affected platforms

• Windows 10 x64
• maOS 10.13
• Ubuntu 16.04 x64

Steps to reproduce

1. Launch FF.
2. Open multiple pages such as (BBC, CNN, reddit, twtitter etc.)
3. Open about:performance
4. Close one of the open tabs from the tab carousel.

Expected result

• Closing one of the tabs from the tab carousel should also close the tab process from about:performance list.

Actual result

• Closing one of the tabs from the tab carousel does not close the tab from about:performance immediately.(only after ~10 seconds if not interacted with)

Regression range

• Not a regression

Additional notes

• As a normal user, when I close a tab from the tab carousel, I would also expect that it will disappear from about:performance list as well.
  Keeping that in mind, I will attempt to click the X for the tab in the about:performance list multiple times to remove it from the list, but only end up with it stuck in the section for another 10 seconds from each click.

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.
