After upgrading to OSX 10.4 (Tiger) I found that Firefox crashed each time I tried to load it. I checked this with Firefox 1.0.3 and 1.0.2 but both had the same problem. Out of curiosity I downloaded Camino and that had the same problem.

With a bit of digging on the OSX support forums I found half the solution and with a little bit of checking finally got it fixed.

The problem is caused by the Java Embedding Plugin, which I had installed some time ago and forgotten about. The version on my system was not compatible with OSX, though the new version is. To get around this I deleted the following directories and everything worked.

/Library/Internet Plugins/MRJplugin.plugin
/Library/Internet Plugins/JavaEmbeddingPlugin.bundle
~/Library/Internet Plugins/MRJplugin.plugin
~/Library/Internet Plugins/JavaEmbeddingPlugin.bundle

For those of you who don’t know the ~ means my home directory, so /Users/jay/
