I've been happily using Opera as my default browser at home for the last couple of years, but I find it's been really crashy on me lately.
So when I started up Firefox this evening, I checked the little box to make it my default browser instead.
However, I'm now finding that it's not integrating with Star Downloader properly (I'm using the Free Version), which is very annoying, given my MP3 harvesting binges of the last while.
*sigh*
Addendum (07 October 2004): Fixed the integration problem with Star Downloader -- turned out that some of my QuickTime settings had gotten changed somehow. Back to downloading mayhem.
