After many, many years of Firefox being my default browser, it's now become unusable. About 6 weeks ago, the BBC iPlayer radio stopped working correctly. Now the browser randomly goes partially or wholly black. Also, when I close the browser (with multiple tabs open), when reloaded, it displays a single page. Closing & reloading again brings up the "well this is embarrassing" screen with the tabs listed below. I tried the "refresh" thing - made no difference. What have you done to it? PS: Typing this in IE.
