1406968 - update alert flashes on and off too fast to read

Status: RESOLVED WONTFIX

(Firefox :: General, defect, P5)

Description

[Patrick Hubenthal]

Attachment: FFUpdateNotice-170928.jpg

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053838

Steps to reproduce:

Launch Firefox while an update is available, with the main Update preference set to "Check for updates, but let you choose whether to install them." Then wait; in my experience the update alerts don't start appearing until my Firefox session has been open for quite a while. I haven't paid close attention to the timing but it seems like it can be as much as 24 hours.


Actual results:

Eventually I start seeing a small box that appears at the top of the screen and instantly disappears before I can read it, or even see what it is. I finally started making screen recordings, and by playing them back frame by frame I was able to see that the box is a Firefox update notice.

I notice it appearing in three situations: a) when I switch to another app, then switch back to Firefox, b) when I switch back and forth between multiple Firefox windows, and c) when I close a dialog in Firefox (e.g. Print).

I first noticed this when the FF 55 update was available (see https://support.mozilla.org/en-US/questions/1173537) and am seeing it again now that FF 56 is ready for me to download.

I'm attaching a screenshot of a frozen frame from one of my screen recordings.  In this particular instance the alert stayed onscreen for two whole frames, or about 0.03 seconds. That's unusual; normally it's onscreen for less than a single frame. The screenshot I attached to the Support Forum question linked above is more typical.

You may notice in the screenshot that I have a few add-ons installed, but I've also tested this with all add-ons disabled, and the alert is still just a blur.  I'm currently running FF 55.0.3 on macOS 10.12.6.


Expected results:

By the looks of the alert, I would assume it's supposed to stay onscreen until I dismiss it by clicking either "Not Now" or "Download Update."

Quick correction: I don't actually see the alert when I close the Print dialog, but I do see it when the "Enter name of file to save to" dialog opens for a download.

Hey Rob, is this a known issue?

It isn't a known issue but looking at the screenshot I noticed that the hamburger menu is missing and the doorhanger hangs off of the hamburger menu.

Reporter, how were you able to remove the hamburger menu?

This should be shown on the right side of the same toolbar as the one that contains the url bar

With the line

    #PanelUI-menu-button { display: none !important;}

in userChrome.css.

That is likely the cause. Try reproducing without that.

Will do, although it'll have to wait until FF57 becomes available for me to download – I've updated to 56 since posting my original report, so I'm no longer getting the update alert.

Thanks to the 56.0.2. update I didn't have to wait for FF 57, and I can now confirm that when the hamburger menu is not hidden, the update alert hangs off it until dismissed, as I assume it's intended to do. Thank you for figuring that out, Robert. I'm not sure how to resolve this bug appropriately so I'll leave that to you and Panos.

We're not going to handle the case where the hamburger menu has been hidden via userChrome.css so wontfixing
