[GTALUG] Request for demo on Firefox's Web Developer capabilities

[William Park]

Hi all,

For network tracing of something that is initiated by browser, I
recently discovered Firefox's 
    Web Developer > Network
which is more immediate and convenient than Wireshark's 
    Analyze > TCP Follow.

But, I'm not a "web developer" and don't know what most other tabs mean
or where to use them.  So, I would like to see a quick demo or tutorial
of Firefox's Web Developer capabilities, say 20 minutes max.  If you can
cover other browser's debugging capabilities, that would be a bonus.
