Abrowser's buttons font color white is very hard to read

As described in my post in the forum:

Since a few updates I noticed that abrowser's default buttons font color was changed to white, making them very difficult to read with their gray background.

I noticed also that the close tap button for the active tap is also white so I think it may be related.

In my mentioned forum post I described a work around for now, but I'm hopping this would be fixed in future updates. Thank you.
