Have you ever had a feeling that there is a missing option you would like to see in Firebug? Well, there is a chance it's there and you just didn't know about it.

In order to keep the UI simple (and we all know options are evil), some options/preferences doesn't have its own UI representation and are accessible only through well known about:config page in Firefox. Some of them really deserve being hidden, but I think there could be some you can find useful.

Since revealing these preferences from source code is quite tedious task, I did it for you and put together a list that summarizes those available in Firebug 1.5.

Note that one of the efforts of Firebug team is having a stronger sense of which features Firebug users actually use. In this particular case, it could reveal the fact that some hidden preferences are often changed and they could eventually made it into Firebug's UI (and vice versa). See more about Firebug user survey (so far still in academic phase). What do you think about this way of providing automated feedback? Could this help us to improve Firebug?

I have recently got several questions about how to understand the timing numbers provided by the Net panel in Firebug and so, I decided to write a quick summary explaining what everything is the Net panel actually measuring (in terms of time).

Just to note that there is already a post, I wrote a while ago, summarizing all other features of the Net panel using bunch of screen-shots.

This post is dedicated only to timings as it's being implemented in Firebug 1.5.3.

I have been recently working with Sergey Chernyshev, who is the author of ShowSlow, on a new support for uploading HTTP tracing data (collected by the Net panel in Firebug) to the ShowSlow server.

This neat feature simply allows to upload the data in HAR format to the server and share them with others online.

Note that similar thing (uploading and sharing of measured data) is also supported by YSlow and PageSpeed (also using ShowSlow).

Another good news is that ShowSlow is an open source (I love open source!) and so, if you want to keep your data private while having the advantage of simple sharing (and other nice ShowSlow fetures), you can download and install your own copy of ShowSlow server (and also avoid limited upload history on the public instance).

So, read more if you are interested.
