Comment 2 for bug 172419

I have been plagued with this bug as well. Firefox grayed out almost constantly when I opened new windows. At first I thought is was caused by Flash but disabling flash didn't solve it. After disabling all Firefox add-ons I noticed that Firefox worked without any flaws. I discovered that as long as I do NOT enable the Google bar add-on Firefox is stable again. The add-ons I have enabled are Flash, Webdeveloper, Addblock and Ubufox.
I am not sure if this is actually a bug in the Google add-on or that there is some other bug floating around that just happens to be 'activated' on my system when I have enabled the Google bar add-on but I can reproduce the problem any time I enable the Google bar add-on.
