should I delete the old version of firefox before installing a new version? If so, then how can I remove and how?

I have an older version of Firefox and adobe on a Sony VAIO. I get telling me to update the pop-ups and also frequent failures when I try to use the browser. I try to upgrade. I go through the process of downloading, then try step execution and get a message 'not allowed '. I checked and I have administrator privileges, and I have disabled the firewall security software, thinking that it does not block the installation, but nothing works. Nobody knows if the older software are the cause and should be removed until the last version can go. Also, if this problem is solved I will have the same problem with Adobe?

What version of Firefox is installed on the computer?

You can find the full version of the current version of the current Firefox (37.0.2) in all languages and all systems operating here:

If you have a very old version of Firefox, then you might consider uninstalling this version of clean up the existing registry keys (especial the uninstall key).

Be sure NOT to remove "personal data" when you uninstall Firefox, because that will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

Check the Firefox program folder and delete the Firefox program folder if there are still files left in it.

  • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.

Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.
