firebug slows gmail

It appears that Gmail started warning Firebug users last month that “Firebug is known to make Gmail slow unless it is configured correctly.” Gmail offers a solution that you can improve the performance: disable Firebug*. Very clever, very clever. :)

I disable Firebug most of the time and only enable it when I am using it - because, well, it slows things down.

*There’s an alternate solution that works for Windows and Linux, but not Macs.
