1378783 - Inconsistent size for buttons inside Preferences

Status: NEW

(Firefox :: Settings UI, defect, P5)

Description

[Bogdan Maris, Desktop QA]

Attachment: Fx54 Content buttons.png

[Affected versions]:
- Firefox 54.0.1
- Firefox 55 beta 6
- latest Nightly 56.0a1

[Affected platforms]:
- Ubuntu 16.04 32/64bit


[Steps to reproduce]:
1. Start Firefox
2. Go to about:preferences#privacy (for Nightly) / about:preferences#content (for Fx 55).

[Expected result]:
- All buttons (except for the those who contain longer strings) have the same length.

[Actual result]:
- Different buttons (even those that contain the same string) have different sizes.

[Regression range]:
- Quite sure this is not a recent regression (repro on 54 as well). Will search for a regression though asap.

[Additional notes]:
- Added two attachments showing that the button size is not consistent.
- Did not saw this in Mac or Windows.
