I have a Mac running OS X 10.9.5. Firefox began to hang on start up. After going through all the troubleshooting solutions suggested I attempted to delete and reinstall. Problem continues. When I checked the Trash basket after deleting Firefox the icon does not appear. The only software loaded around the time of Firefox beginning to hang was perhapss Skype. My laptop running OS X 10 10.10.2 is able to run Firefox fine. It is not enabled for Skype. Could there be issues with Skype?

Firefox and Skype are separate programs.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

Download Firefox Full Installer For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.

Look for, and rename any Mozilla and Firefox folders by adding .old to them.

Now run the full installer. If all goes well, remove the OLD folders when you are done.
