828684 - Using mouse wheel to scroll tab bar causes window to resize

Status: RESOLVED INVALID

(Firefox :: Tabbed Browser, defect)

Description

[Eric Shepherd [:sheppy]]

Starting within the last couple of builds of Firefox nightly, using the mouse wheel to scroll through the tab bar has, after a few moments of scrolling, caused the window to resize. If I'm scrolling to the right (that is, wheel moving down), the window maximizes to fill the screen. Scrolling the other way shrinks the window down to a small box on my screen.

This is really awkward!

I was unable to reproduce this issue on the 2013-01-09 Nightly build. I have tried several times with 100+ opened tabs.
Can you please add more details like any installed add-ons or the number of tabs used?

Could you please verify if this is reproducing in safe mode?

Huh. I just tried something and discovered this is happening in other apps too if I work the mouse wheel while pointing at the title bar. Some Mac utility I use must have added a "feature" on me recently. I will hunt it down and kill it with extreme prejudice.

(I only really use the mouse wheel to scroll the tab bar; normally I'm a scroll bar user for actual scrolling).

Sorry for the bogus report.

FWIW - the culprit was HyperDock.
