After uninstalling 0.9.4m removing the directory and installing 0.9.5 (126.96.36.199.5.2001101120) or build 0.9trunk2001101606 the browser gives and error and doesn't start. The trunk build gives "Error launching browser window: no XBL binding for browser" 0.9.5 build gives "Error creating browser instance" Mail also doesn't display any controls.
I tried a new nightly today, and the problem still is there. After the install I get this error message: Cannot find entrypoint of procedure ?ToNewCString@nsString@@QBEPADXZ in xpcom.dll (translated from dutch) When I try to restart the browser after the install I get the previous reported error message ( no XBL bindings for browser) and yes I installed in a fresh directory after an uninstall of the old version.
The profile from mozilla 0.9.4 was causing this. Starting the profile manager mozilla -profilemanager and creating a new default profile fixed the problem. Might be something that a next build might automagically do if something goes wrong.
