I’m not sure what causes this semi-regular bug in Firefox but it’s driving me crazy. Basically every so often Firefox not longer visually responds to mouse or keyboard actions in the main window. If I change tabs, I can see the page name switch at the top of the window, but nothing seems to be happening in the main space. I have to quit the browser and start again… several times per day at least.
I tend to keep Google Reader, GMail and a few others going at all times, but have seen it with just GR open as well. Anyone else get this?
