Starting today, I cannot get the Plugin Check page to load. It gets as far as "Checking with Mozilla on the status of your plugins...", and then hangs.

In the error console, I see: Error: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0" data: no]

Is this a known problem with the page, or do I have to wipe my profile yet again to get Firefox to work properly?

OK, via a process of elimination, the problem seems to be caused by Page Speed 1.9; I've disabled the add-on, restarted Firefox, and the plugin check page loads perfectly.

Now I just need to find a way to report the problem to Google.
