1906208 - Process Manager: clicking x in tab does not close tab in 127.0.2

Status: RESOLVED INCOMPLETE

(Toolkit :: Performance Monitoring, defect)

Description

[mgryan]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:127.0) Gecko/20100101 Firefox/127.0

Steps to reproduce:

run Mazilla Firefox 127.0.2
Press SHIFT-CONTROL
In Process Manager tab at top of screen click on the 'x'

Actual results:

Tab does not close.

Expected results:

Tab should close.
Right click on the same tab, pull down to "close tab"
Tab does close correctly.
Underlying functionality works, GUI interface is broken.

Priority level: there is an easy work-around (the above), but if the user
doesn't think of it, he's stuck. He'll have to close Firefox.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I just tried reproducing in Nightly (129.0a1 (2024-07-03) (64 bits)) on Mac and couldn't reproduce. So either there's a step I didn't understand, or it doesn't reproduce for me.

When the problem occurs, is there any error reported in the browser console?

I am now unable to reproduce this bug in same version (127.0.2 for Windows).
I don't know what's changed--other than I just opened Firefox. I will try again after Firefox has been active for some time.

I didn't look at the Browser console when I initially observed the bug. I should have--sorry

I apologise, I seem to have made a mistake. I mistakenly closed the processes and not the tabs themselves when first testing. Re-tested both Firefox Nightly 130.a1 and Firefox 129.0b2 and I can confirm that the issue is not reproducible on my side either, as the tabs close without any problems whilst pressing Shift+CTRL/CMD. No errors in the browser console as well. Setting the status back to UNCOMFIRMED until further confirmation is received. I’m very sorry for the confusion.

Given comment 4 and comment 5, I'm going to resolve this as INCOMPLETE.

mgryan, if you see this again, we can reopen.
