Is there a firefox extension that...
 

... can show me the size of the current page in kb? (HTML+pictures/flash)?

:question :question :question

yeah would be good to know

opera displays the kb loaded and the kb in total in the lower left corner..

Found one here:
http://mozilla.queze.net/

but I'd love to have it displayed in the status bar like this one, which unfortunately doesn't display only the html-size:

I guess it wouldn't be that hard to implement, as firefox has all the information ready in tools -> page information, but all split up...
