Can't test/modify/change items with firebug

[Quidico Suave]

Im new with firebug (firebug lite for chrome). I "tested" some stuff earlier and now I can't anymore. Let me give you an exemple: I used to click on inspect and then change some stuff in the right box (width for example) just to see how it would look like. The changed were applied automaticaly and so I knew my code was ok and I could put it in my website. 

Now, if I change something, it doesnt apply, i cant see what the modification look like. What happened? What did I do wrong?

Did you test that on the same website? Do you see any errors in the console? Do you have a link, so this can be reproduced?

Yes I did test it on the same website. Now its worst: the console doesn't even appear anymore. www.cirquevirevolte.com is the website im working on right now. Im doing it with WordPress. When I go to my wordpress dashboard, the console appears (and its very annoying bc it keeps popping every page or click I do, but not on other websites)

Ok, looks like this problem was already described before.
I can see this error in the DevTools console:

Uncaught TypeError: Cannot call method 'push' of undefined   firebug-lite.js:30905

I didn't find an issue in our issue tracker with this error message, though there's probably already one describing the same thing.
Gal, maybe you can help out here.
