I am having problems with google, website, and many others with 16.0.1 and mac os x 10.6.8. Google news does not display properly or work properly. Youtube is hosed too.

I'm not sure if this is the same issue... I created App Tabs in 16.0.1. Initially they worked, but then stopped during my same session. The tabs are still there, but they do not operate. I can still go to their referenced sites fine by opening a new tab and putting in the address. The non-functional app tabs persist when I close and re-open FF. They're just taking up space on my tab bar now. I can't even delete them (don't know how).

Thanks for your responses!

@bobsmithofd, I'm using FF16.0.1 on Mac OS 10.8.2. @Cairngorm, not sure, but I think my Panorama view may have worked at first when I initially opened the new version, but when I needed it, I couldn't get to it. Later, the visible tab group changed without my having done anything knowingly to cause it to change.

I ended up creating a new browser window, then experimentally dragging all of my tabs manually into the tab bar of the new window from the only visible tab bar of the old window. I then clicked the tab view button in the new window and it showed Panorama. In the old window, another group of tabs was in the tab bar, so I dragged those over, as well, creating a new group in the new window, which I named identically. I repeated this for a couple of hours until the old window disappeared. The new one works fine.

That doesn't work in my problem. When I start FF, the Windows "wait" icon spins inside the app tabs, but when they stop, the tabs are still completely inactive. And I can't drag them to another window; it's like the tabs become part of the frame for the window.

I have the same problem in Windows XP.

bhupendra, my problem turned out to be the Shockwave Flash 10 that was an add-on. After disabling it, I got returned access to the app tabs.

I was helped on this in another thread!
