Description (last modified by trev)


Nightly 51.0a1 (20160918030408)
Windows 10 Pro

How to reproduce

  1. Install/Update to the latest dev build

Observed behaviour

The ABP icon disappears from the navigation bar.

Expected behaviour

The icon should stay.


  • The drop down icon is still clickable
  • Also reproducible with Firefox 48.0.2


In #4409 we set a fixed width and height for the toolbar icon. Turned out, on Windows this toolbar icon has paddings in order to accommodate the dropdown arrow - the resulting content size gets too small because of that. Applying box-sizing: content-box to the element doesn't show any effect, probably because of XUL specifics.

  • Priority changed from Unknown to P1

  • Resolution set to fixed
  • Status changed from new to closed

I rolled back the change in question with - it seems that the fix only works on OS X and breaks things on Windows. Currently I don't see any approach that would work with both, the platform-specific Firefox themes are too different.
