Re: Firebug reports JavaScript error in Facebook all.js JS API

[Sebastian Zartner]

Doesn't sound like this problem is related to Firebug. Do you still get the error when Firebug is disabled for your website? (Check the Firefox Error Console.)

[Sebastian Zartner]

According to the stackoverflow thread this is a test of all.js related to the JSON implementation of the browser. So it doesn't sound like it has something to do with Firebug.

@John:
Please deactivate Firebug and check if the error is still thrown. If yes, it's unrelated to Firebug. If not, please give a URL and steps to reproduce your problem.
