keep trying to install latest version of firefox, looks like it has installed but on checking find it hasn't (Mac)
On loading Firefox - advised to update to latest version 39, current one is 35.0.1. Downloads OK. Appears to install, move to Applications as instructed - replacing existing copy. Relauch and I find I am still using version 35.0.1. Running on Mac with OS X version 10.9.5

these are the instructions that i followed originally - they did not resolve the issue.
Something may be blocking the install.
Start your Computer in safe mode with networking.

Then run the installer.
I've called the big guys to help you. Good luck.
