Same happening here, except system is XP SP3, fully updated.

Used Help > About Firefox to update Firefox (Australis) 28.0a1 this morning.

Message: 
The application has failed to start because pgort100.dll was not found. Reinstalling the application may fix the problem.

What I tried:
1 Uninstalled 12-09-2013 update to Firefox 28.0a1 leaving profile
2 Download and reinstalled 12-09-2013 full installer
3 Same problem.
4 Downloaded 12-08-2013 full installer, installed over the top of 12-09-2013
5 Started Firefox and 12-08-2013 update worked
6 Ran update (to 12-09-2013) using Help > About Firefox and same error message on startup of Firefox
7 Ran full installer of 12-08-2013 over the top of 12-09-2013 and restart worked.

Problem appears to be with something in 12-09-2013 update/installer for Firefox (Australis) 28.0a1.
