### Issue description, userChrome.css/userContent.css 'settings' the issue occurs with and steps to reproduce the issue

Yes, with the latest release

### Screenshots showing the issue



### System information

- OS & OS version: Windows 8.1
- DPI/HiDPI/scaling value, if not 100% (e.g. 125%, 150%...): 100%
- Firefox version: Nightly 138.0a1 (2025-03-22)
- Firefox theme (e.g. default, build in light/dark, external theme + link): It can be seen on any color theme.

Start by reproducing the spacing difference in Firefox Nightly 138.0a1 with the CustomCSSforFx files installed, then compare the address-bar buttons with the screenshots. Inspect the CSS under the /chrome/ folder and the relevant userChrome.css settings; done means the button gaps are consistent without changing other address-bar behavior.
