[Affected versions]:
- 62.0.3, 63.0b12, 64.0a1 (2018-10-08) 

[Affected platforms]:
- win 10x64, Ubuntu 16.04, macOS 10.13

[Steps to reproduce]:
1. Launch Firefox;
2. Access about:preferences#home
3. Click the dropdown for the Homepage and new windows option;
4. Click on Custom URLs...
5. Grab the browser and resize to shrink its width.

[Expected result]:
- content is properly displayed;
- not sure of the proper behavior, but probably the button width should remain the same to contain the text;

[Actual result]:
- the following buttons are changing width to adjust for resize but text is overflowing: [Use Current Pages], [Use Bookmark...]

[Regression range]:
- introduced with bug 1417155

[Additional notes]:
- attached screenshot with the issue;

This is caused by the buttons having -moz-box-flex (flex=1 attribute) and a defined min-width ( https://searchfox.org/mozilla-central/source/toolkit/themes/osx/global/button.css#12 , https://searchfox.org/mozilla-central/source/toolkit/themes/linux/global/button.css#16, https://searchfox.org/mozilla-central/source/toolkit/themes/windows/global/button.css#16 ), which in XUL means they can be resized as part of flex. There's a trivial fix for this, I'll just put up a patch.

While this may have regressed as part of bug 1417155, that's only because this stuff is now in its own column so there's less available width in the first place. I bet in locales with longer labels this would have been reproducible in the old layout, prior to bug 1417155.
