Using Firefox on Win7(64) for a while, the taskbar-con-prewiew shows sometimes much more previews than open tabs.
It looks like the preview-funktion is not refreshening properly

Reproducible: Always

Steps to Reproduce:
1.use Firefox with many changing tabs (websites)
2.close sites, open new ones
3.check taskbar preview against open tabs

Ever confirmed: true
Are there any error messages or specific reliable steps to reproduce? I have seen this on occasion but have not managed to reliably reproduce it.

no error messages, just using latest version on a computer specified:
Firefox on Win7(64)
f.e. opening links from thunderbird-mailas
opening favorits

I don't know how to reproduce this issue, but my browser is currently in this state where I'm seeing previews of closed tabs. However, now I *cannot* close any tabs by clicking on their X buttons, or using Ctrl+W, or even middle clicking on them in the preview pane. Creating new tabs with Ctrl+T works, but I can't close them either. These two issues may be related since the latter has only happened after the former (Firefox 4 Beta 6 from rev 633e895d5e84).

Here's what shows up on my error console when my browser is in this state.
This looks a lot like bug 545077.
