This is a known issue that appears specific to using FireFox on WIndows XP. It has been reported to RightNow but has not been corrected. Don't know if RightNow or Mozilla did the change that broke this. I've been able to use Firefox on Windows XP by book marking the pages referenced by the "file tab" buttons at the top of this screen and using the bookmarks in place of the tabs.
Thanks as always, Phil.
I'm actually using Firefox on a Mac (10.8.2).
It seems Safari works OK so I'll just use that from now on. Must be a recent issue with all the updates to Firefox every few weeks.
I'll pass that info on to ModMan--the FileMaker Inc. manager in charge of this forum, Firefox in Windows 7 seems to work just fine.
I'm using Firefox 17.0 on Ubuntu 12.10 (Linux distribution)
And that bar is also not working for me.
