the Question is it. the overlap prevents me from easily accessing controls on the navigation bar. I don't understand this. I asked this earlier and got dumped because i changed all the files as requested and the problem hasn't gone away. I downloaded and installed Firefox 17 and it is still there! I also upgraded my operating system to mac OS 6.8 with no help at all. I can get you a copy of the start up reading from the console if you want. I've included a screen shot below..... wait. I just reverted to the default persona from a musical one - the problem disappeared. Why do I get this when I add personas? Let me try others.... That is the focus of the problem! The personas for some reason exclude some of the toolbars and "shove" the title bar down onto and superimpose it upon the navigation bar. That may not make sense, but that is what it looks like from this end. Curious, though, the drop down options are still in a strange configuration, a different typeface than they were before, which happened when the personas superimposed the title bar on the navigation toolbar. So, obviously I can't use the personas. Is there a way around this, please? there is obviously a conflict somewhere, bit I can't figure it as this is a new development ever since I tried to install a new glims version for Safari and this problem appeared after that. De-installing glims did not eliminate the problem so it obviously changed something in the Firefox configuration files. The guy at glims was mystified, too. Any suggestions? thanks.
