Sharp cornered address bar edge outlines

[Jono Hewitt]

Firefox 76.0b2 Beta - MacOS - Dark theme
ShadowFox installed via the shadowfox_mac_x64 executable.

When selecting the address bar, the ShadowFox edge glows with a sharp cornered rectangle which overlaps with the rounded edge glow from default Firefox, leaving a dark corner in between the two outlines.

Same on Linux since the new Firefox (and new address bar) update.

If anyone has CSS fix or another workaround for this please share!

One alternative is deactivate the new address bar going to about:config and switching browser.urlbar.update1 to false.

Since Firefox 77 this solution does not work anymore.
There is an alternative solution for reduce the size of the bar here, but the problem with the edge outlines stills persist on this case: https://support.mozilla.org/sv/questions/1289355
