I just checked in new revisions of the back, forward, reload and stop icons for Mac Firefox by icon wizard Stephen Horlander. These new buttons attempt to address the critics of the previous set, and they share their shapes with the Windows Firefox theme. We went with a more colorful toolbar this time instead of making the nav icons all blue. This will probably be the final major change before Firefox 1.0 is released.

After the release of “Winstripe” into the wild there was a large and varied response. Ranging from mindless petulant rants and demands, to well thought out critiques. Lets just say there were more of the former than the latter. Even before it’s inclusion in Firefox I was personally less than thrilled about how it turned out. The idea, as you may have read, was to take the icons from Pinstripe and make them fit into a Windows environment. The theory was sound as the icon concepts used in Pinstripe were, I feel, fairly strong. Due to time constraints and my own admittedly limited familiarity with more recent incarnations of Windows I think they failed on this count. They do however work well enough and are a good deal better than most of the icons used by many Windows applications, in my biased opinion anyway : )
You might have read that Firefox is getting a new default theme. Here’s a first look. I’ll post more about the making of the theme in the next few days.
Edit: I appreciate all feedback, negative as well as positive, but please reserve final judgement until you have actually used the theme

New Name. New Look. New Icon. The program formerly known as Phoenix and Mozilla Firebird has just released version 0.8. This version is faster and more stable than before and has more neat features than you can shake a stick at. Check the release notes. It also features the Pinstripe theme as the new default look on Mac OS X. Download it here!
Note: The Firefox UI may appear broken if you are using a previous version of the Pinstripe theme. Go into your theme preferences, select “Firefox (default)”, then close and reopen the browser to make sure you are using the latest incarnation of the Pinstripe theme.
Here’s a Mozilla Firebird build for the Mac, home made and fresh out of the oven. This build has some nice bug fixes. Check it out! See this page if you’re interested in building Firebird yourself.
