1.4: you have to manually reload the first time

Friday, July 3rd, 2009

Based on newsgroup postings, users did not get the news that Firebug 1.4 requires a manual reload the first time you open it on a site. Ok, no I don’t know how they would know. So here it is:

In 1.4, when you open Firebug on a page it does not automatically reload the page. You have to do it manually.

In 1.3, the page was reloaded for you. We made this change because some users (ok it was Steve ;-), complained that the reload was not always necessary and sometimes wastes time. This is especially true for users who are primarily interested in HTML and CSS or for users who want to know just when the reload is triggered so they can watch how the page loads.

But why do we need to reload at all? Well to track net traffic, to track script loading, and to listen for console logging we have to add listeners on the page before the page load begins.   If Firebug is not active at the time of page load, none of this happens. So after you open Firebug you have to reload to get all the info. That was true in 1.3 and it still true in 1.4. The only change here is that 1.4 you have to do it manually.

By now my brain automatically hits reload when I open Firebug, since I always want all the info on all the panels

Firebug 1.5a7with Activate Same Origin

Wednesday, July 1st, 2009 has Firebug 1.5a7. This release has one new small feature for users who have sites that generate unique URLs: “Activate Same Origin”. When this option is on, all pages with the same “origin” as an active page will be active. So, for example, if you open Firebug on, then visiit or, Firebug will be open. (This is close to the same-origin policy used by the browser).

Also in this version are some important bug fixes:

  • Issue 1894: CSS-edit removes declaration if page with specific javascript.
  • Issue 1879: nsIStreamListener.onDataAvailable throws exception
  • Issue 882: console.log() reports wrong source file and line number

All of this will appear in Firebug 1.4.0, “soon”. Note that if you install 1.5 it should work well but updates will begin to diverge from 1.4 and at that point it will be, well, ‘alpha’ quality.


Please post followups to the newsgroup.
