Firefox problem with text hightlighting and scroll bar

[Soulaymane Lamrani]

Hi gecko,
There seem to have a problem with my installation of Firefox-54.0.1_1,1. The problems appear when I run Firefox. It appeared with the latest update. I can't see the highlighting effect when I highlight text. And there is also with the scroll that does not show. The problem appears each time I installed Firefox from the package. So I installed the firefox-esr (52.2.1) to test and the problem does not appear. (I installed all my programs from the packages with pkgng, if it helps)
