I decided I would be brave and download Minefield (the latest “trunk build” from Firefox) and try it out. I have been reading several reviews about how fast it is, and wanted to see for myself.
I was not, however, able to use it at all. First, my current setup. I am running OS X 10.5 on a 17″ MBP with 4GB RAM. (I have the older mobo however, and the system only actually uses 3GB.) I also have Parallels 3.0 installed with a Windows XP VM (this is important) and two Linux VMs (a Gentoo server and an Ubuntu desktop).
When attempting to start Minefield on OS X (Parallels not running), as Minefield starts Parallels attempts to start an installer on Win XP. The VM cannot be shut down until Minefield is shut down and the only way to do that is via Force Quit. Otherwise the installer continues to attempt to run on Win XP in Parallels. I did not download the Windows installer, nor did I wish to, however, there is something that is triggering a “Firefox Installer” on Win XP whenever Minefield attempts to open on OS X.
Needless to say, while Minefield will not start until it has finished “installing” on XP, and since it is trying (I guess) to install the OS X version on XP, I end up with a hung Minefield and an endless loop of Windows error messages (“The application Firefox Installer has performed and illegal operation etc etc”) followed by the “Firefox Installer” on Windows dying and respawning. Maybe I’ll try again in a week or two, since these are trunk builds and fixes and updates are coming in pretty regularly at this point.
