Firefox Firebug Addon only grey Window

[Luca Koch]

Hello all!

I use the Firefox Add-On Firebug. Over years it works without any problems but today I start it and the whole window was just grey (Screenshot).
Can you please help me? Need it to work.

In another thread somebody wrote that this is caused by the extension Webpage Snapshot - Snapilicious.com 3.15. Do you also have that extension installed?
I already have added a workaround for that in Firebug and contacted the authors of that extension.
