Cannot switch tab by clicking top edge of monitor

[ndc]

Before 145.0 upgrade, when Firefox is maximized on the screen, I can click the top edge of the screen above a tab to switch to that tab. After 145.0 upgrade, clicking the top edge is not registered. I have to lower the mouse a few pixels to enter the clickable tab area. This is a reduction in usability because previously I can just slam the mouse cursor to the top and slide left or right a bit. I didn't have to aim the mouse too accurately to enter the clickable tab selector.

This is really annoying, almost every time I want to switch tabs. I really hope this changes!

I created an account just to give this feedback because it is that bad. Please expand the clickable area!

Looks like this issue is already reported in https://bugzilla.mozilla.org/show_bug.cgi?id=1993474

Is there a workaround to this? Like maybe a configurable flag in about:config? 

Otherwise, I hope this gets fixed soon. I'd hate to see this turn out to be a "feature" -- as this is how older Chrome/Edge browsers treat their tabs. Annoying indeed!

Hello

Is it this subject.

https://support.mozilla.org/en-US/forums/contributors/717454#post-89662
widget.windows.windowsappsdk.enabled to false make this go away?

1 - Go to Configuration Editor for Firefox https://support.mozilla.org/en-US/kb/about-config-editor-firefox
2 - Enter a search term widget.windows.windowsappsdk.enabled

To complement.
Apparently a similar discussion.

Hello,

I fully agree with original post; this is super annoying. I know this is fixable in config, but to be honest I don't see why anyone would want it any other way. Intuitively, when I want to go to a different tab, I just smash my cursor at the top of the screen, approximately where the tab is. Tabs are large, but very thin (vertically). So it makes sense to make the top edge clickable. I think it would be better to revert it.

EDIT: apparently this is a bug and not desired, therefore it will probably be fixed.

Another finding: the issue happens if the first monitor and the second monitor have different 'scale' (in Windows right click the background - Display Settings - Scale & Layout - Scale). My first monitor (the laptop screen) is scaled 125% while my second monitor is scaled 100%.

I tried to set both monitor to 100% and the issue went away. Resolution doesn't matter. I set the first monitor to 1080 and the second monitor to 1440, as long as both have the same scale, it was fine.

Just tested and this is my exact scenario... however I am on a desktop with 2 monitors

When I tried both 100% resolution scale the issue remained, but when I set them both to 125% the issue went away

Additionally when I set my normal resolution scale of 125% on the 1440p and 100% on the 1080p monitors the issue remains on the 1080p monitor while the 1440p w/ 125% scale the issue is gone.

Wenn Sie auf unserer Website feedbackmcdonald.de (oder anderswo) nicht durch Antippen des oberen Randes Ihres Monitors zwischen den Registerkarten wechseln oder diese anklicken können, lassen sich die häufigsten Ursachen in wenigen Sekunden beheben: Überprüfen Sie zunächst, ob Sie sich im Vollbildmodus befinden, und drücken Sie F11 (Windows) oder Strg+Befehl+F (Mac), um diesen zu verlassen, damit die Registerkartenleiste sichtbar und anklickbar bleibt. Stellen Sie zweitens sicher, dass Ihre Multi-Monitor-Konfiguration in den Anzeigeeinstellungen richtig ausgerichtet ist, indem Sie die Monitorfelder so verschieben, dass sie ihrer tatsächlichen physischen Anordnung entsprechen, da eine Fehlausrichtung häufig eine tote Zone am oberen Rand verursacht. Deaktivieren Sie drittens die Hardwarebeschleunigung in Ihrem Browser (Chrome/Edge: Einstellungen > System > „Hardwarebeschleunigung verwenden“ deaktivieren und dann neu starten), um alle GPU-bezogenen Störungen zu beheben. Probieren Sie diese drei Schritte der Reihe nach aus, und das Klicken am oberen Rand wird in praktisch allen Fällen wieder einwandfrei funktionieren
