Pale Moon forum

In the lastest versions I notice an aesthetic issue with the adress bar: it has a double border. It doesn't affect the functionality, but I find it very annoying.
In 27.4 there wasn't this issue, there was only one border.

Awaiting for a fix, do somebody knows if is there some workaround using Stilysh? (eg. #urlbar css, but I cannot find an exaustive DOM of the urlbar...)

Issue present still to 27.9.3. There was NOT PM but Australium theme. Problem fixed with last theme update, there is not double border anymore
