NOTES:

Before that, when I was messing with tabs, I got:

JavaScript error: , line 0: uncaught exception: [Exception... "Component
returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)
[nsIJSCID.createInstance]"  nsresult: "0x80570015
(NS_ERROR_XPC_CI_RETURNED_FAILURE)"  location: "JS frame ::
chrome://global/content/bindings/tabbrowser.xml :: get_fastFind :: line 1569" 
data: no]

Perhaps this is relevant...

bz, is this by chance related to the --enable-extensions=all bug you filed
around this same time?  Can you still reproduce if you don't build TAF?

[Boris Zbarsky [:bzbarsky]]

Yeah, without TAF this bug seems to not be around....
