Google Chrome has quite quickly become my main browser for everyday use but when it comes to development I still have to slip back to Firefox.
This is starting to change a while back with Firebug releasing a "lite" version via bookmarklets (which is compaitble with IE6+, Opera, Safari and Chrome).
A bit more on Firebug Lite:
Firebug Lite is a pure Web based version of Firebug, built on a different code base than the Firefox version. In addition to Pedro's major improvements, he has also been evolving the code to bring it closer to the Firefox version. Eventually we hope to combine the Lite code with a new Firebug frontend for mobile and remote debugging based on a standard web debug protocol.https://chrome.google.com/extensions/detail/bmagokdooijbeehmkpknfglimnifench
