Who let the dogs out?!?!? If you hadn't seen the news yet, Firefox 3 (dogs = canidae, and so are foxes...) has been officially released. This is exciting news for all web warriors, regardless of operating system. While this fox doesn't quite match up to it's brethren, Safari and Opera in terms of CSS3 compatibility and general web rendering features, it is a huge leap forward for operating system performance and optimization. If you're a Mac user you may remember the 1.5 days, where you could go make a pot of coffee while Firefox was starting up. Firefox 2 was better, but still not where Mac users expect their applications to be. Some of us, for a time, used Camino but that's nothing more then a joke... Firefox 3 is a pleasant surprise for Mac folk, who will notice considerably improved load times and Aqua features we simply expect from real mac applications. I highly recommend downloading this new release if you haven't already.
Disclaimer: I still strongly support the adoption of Safari 3.1 and would still recommend it's use over above Firefox 3 due to it's early adoption of new web technologies and overall integration with the OS X world.
Finally, Safari 3.1! For a long time now I've been using a variety of hacks on my install of Safari to make it more usable. Most notably, plugins like Twicetab which offered the ability to double click in the tab bar and open a new tab, or Safari Stand which opened up a series of debug menu options. The new release of Safari now makes all those things unnecessary. Double clicking the tab bar works - just like you would expect it to, and a "Develop" menu bar is revealed by a simple checkbox in the Safari Preferences. This menu bar reveals access to the Web Inspector, Console and best of all new "Disable Caches" option - something every web develop has been patiently waiting (and hoping) for!
