Is the upper left-most pixel of firefox broken?

Hi there,

I have many tabs open, so eventually I have to scroll through the tab bar by clicking on the arrow buttons to the left or right. My favorite move is the triple-click to get to the very beginning of the tabs.

However, since recently (update to v. 55?) the top-leftmost pixel is "dead" in this regard, it is just not clickable. So pushing the mouse courser into this corner and click or double-/triple-click won't work anymore. I always have to slightly re-position the mouse to do so.

Is it just me, or do others have this issue, too? Can it be fixed somehow settings-wise, or is it a bug?

So I updated Firefox to 55.0.3 and created a screenshot of the issue with the MS problem recorder (psr.exe; sorry, low quality). I took 3 pictures:

1. mouse pointer exactly in the corner 2. mouse moved slightly downwards 3. mouse moved slightly to the right (from the corner)

Although I can't show the result (missing scroll) in a screenshot, the problem is visible in terms of the color (darkness) of the corner area. With slight movement of the mouse the area gets darker and, thus, indicates itself to be clickable.

You can actually see that the first click did not move the tab bar (psr records on click) as in the second pic it still has the same position.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Yep, still there.

Don't you have it?
