Get the makefile instructions to pull When creating a working directory and checking out the source tree and it doesn't really matter where you put it in a directory called mozilla in , but avoid paths that contain spaces. If your user name doesn't have space you can checkout the source to your home directorylike this:(This will create a mozilla directory in your root i.e C:\Users\YourName or whatever.If a directory called mozilla already exits, even if it's empty, it will cause an error.)

cvs -d mkdir mozilla cd mozilla hg clone http:pserver:anonymous@cvs-mirror//hg.mozilla.org:/cvsroot co mozilla-central/client.mk Checkout the source: cd ~/mozilla make -f client.mk checkout MOZ_CO_PROJECT=browsersrc

Another problem is that you may not be able to use your home directory because the path may have almost certainly has spaces. If that is the case, just put the mozilla directory in your root (ie. C:\mozilla) and put the .mozconfig file in that directory.

For instance, the build may have trouble finding the glib dependency. If this happens, try adding this to your path:
