some websites text bars(login) are black in DA and DTPO

I am having a problem with many of the webistes that I go to, especially google(but many others). The login bars and search menus are black. I cannot see what I am typing. Is anyone else experiencing this problem? Any suggestions for how to troubleshoot this?

That’s unfortunately a glitch introduced by Mac OS X 10.7.4 and affecting especially applications still supporting Mac OS X 10.5.x and PowerPC. However, the next releases should fix this issue.

In the meantime one workaround might be to use a custom stylesheet, see Preferences > Web.
