Here is what I am trying:
1) Load
getfirebug.com
2) Enable all Firebug panels
3) Select the Script panel
4) Reload the page.
The page doesn't freeze.
Perhaps it's related a specific page. What page should I use?
Does "Firebug menu -> Options -> Reset All Firebug Options" help?
Does creating new Firefox profile help?

(please backup your old profile so, we can compare if this solves the
problem)
