While I use Firefox 1.5 on Windows as my default browser, on Mac OS X, Firefox just feels unfinished compared to Apple’s Safari. In Windows world, Firefox has leaped frogged the current IE in terms of features, (with stability being reasonable for a third party browser) which makes Firefox a no-brainer choice. However Apple’s Safari is a new browser and while it may not have actual extensions, it still has quite a feature list and it is comparable if not faster than Firefox.
The more annoying problems with the 1.5 release are web site issues. Forms which do not work at all on Firefox work just fine on Safari. I should be fair and say that I have had some issues with Safari along the same lines, but Firefox 1.1 had no such issues. Firefox’s own developers admit that the OS X version of 1.5 was less than stellar:
Firefox 1.5 was a major milestone on all platforms, but it was not quite what it could have been on Mac OS X. We just didn’t have the resources to test for and fix bugs fast enough when release time rolled around. However, not delaying the release was a decision that I was happy with because it was the right thing to do, even if it meant less-than-great Mac OS X support. Firefox 1.5 was still a major upgrade in terms of Mac OS X support, and nothing to be ashamed of.
The problem was that expectations were quite high for 1.5 and on the OS X platform, the expectations did end up being a bit too high. This leaves most OS X users waiting for 1.5.1, or even the 2.0 version, at a time when the Mac world is in drastic change with Intel processor changes. To make matters worse or better depending on what your opinion is, Microsoft has dropped IE for OS X completely. This leaves only Safari and Firefox (and of course Mozilla).
While 1.5 seemed to take forever to be released, Firefox as a whole is moving to more updated releases and stability is still a main focus for the developers. Eventually Firefox will be more competitive on OS X, and perhaps Safari will start changing as well to keep up with some of the ideas the Firefox developers are integrating into their modern browser.
