Affected versions

  • 85.0a1(20201214091023)
  • 84.0 (20201211215739)
  • 83 (20201112153044)
  • 78.6.0esr (20201207224150)

Affected platforms

  • Windows 10x64
  • macOS 10.12
  • Ubuntu 20.04

Steps to reproduce

  1. Open Firefox with a new profile and resize it horizontally until the More tools button is displayed.
  2. Enable Sidebar.
  3. Visit about:profiles/ about support.

Expected result

  • Content is displayed as expected.

Actual result

  • Elements are out of the content box.

Regression range

  • The issue is reproducible with 43.0a1 (20150920030217) with and without the sidebar opened on about:support page so I think that this is not a regression.

Notes

  • Attached a screenshot.

Suggested Severity: S4

Has STR: --- → yes

I can reproduce this with the STR. Note that this is not only that the window is too narrow. The same width content space without the sidebar behaves differently: the "Refresh Nightly..." and other buttons do not overflow their container. Zooming out with control-minus fixes the layout once there is enough room.

Severity: -- → S4
Priority: -- → P5
Product: Toolkit → Firefox
