I'm on a Mac with OS X Yosemite & Firefox keeps asking me to update to 39.0. I keep going thru the process but it keeps staying at 38.0.1. Is it not compatible?

Hello masterminds, try to download and install firefox, do the next steps:

1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html (full dmg package)

2. Trash the current Firefox application to do a clean install.

3. Install the version that you have downloaded.

Do not select to remove your personal data, your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks or other personal data.
