You may be able to reenable Firebug by setting the preferences: - Go to the about:config (type in url bar) - Find xpinstall.signatures.required (set to false) - Find browser.tabs.remote.autostart (set all to false: browser.tabs.remote.autostart.1 and browser.tabs.remote.autostart.2) I'm using Firefox for development, and both Firebug and Firefox development tools, for different purposes (Firebug for DOM and CSS manipulation, which is superior, and Firefox Tools for Console and NET panel, which are cleaner).
