v28.1.0: Taskbar preview fix breaks taskbar icons in W7 Aero Basic

Unread postby LigH1L » Sun, 23 Sep 2018, 14:44

In the release notes you also mentioned:

  • Fixed tab previews in the Windows taskbar (if enabled).

Interesting, since this version the favicons displayed in each tab are not displayed in the taskbar list anymore if I do not use Aero Glass with Aero Peak, but only Aero Basic designs in Windows 7 SP1.

Here a sample of my taskbar preview list, using two windows with several tabs each.

I remember that I reported just the same issue before to the Mozilla Firefox bug tracker, where it got fixed...

Not even a confirmation yet?

Anything in the browser console/error console?

I started Pale Moon in Safe Mode to avoid add-ons interfering.

Browser Console:

Code: Select all

Several more warnings in the Error Console, but AFAICS only CSS warnings.

Do you log Windows API errors at all? I doubt they would appear here.

BTW, the tabs contain all favicons. Only the taskbar list doesn't. Just like the linked old Firefox bug reports.

The Firefox bug existed because someone forgot to rename a calling site when refactoring. That refactoring is not present in our tree and as a result that bug isn't, either.

Running Win7 Home Premium (64bit) I can confirm the blank favicons in PM 28.1.0, (they are present in Fx 62.0.2).

I can also confirm that on Win10 Home (1803) the thumbnails that just showed a loading throbber prior to PM 28.1.0 now show thumbnail images as expected.

Created Issue #809 (UXP) to track this regression.

Of course not, since that GitHub issue is still open.

What is it with people and this release expecting things to have somehow magically resolved themselves?

:cry: I don't expect magic from humans. It was just feedback; no demand, no blame. At most a patient reminder. But maybe I have a talent for making myself misunderstood for the worst.

Take the time you need. I will stop my feedback until it's done. :silent:
