Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

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

Windows: C:\Program Files C:\Program Files (x86)

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

Perhaps you have both 62.0.3 and a 56.0 Release installed on Windows.

Perhaps your useragent was modified https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox

Or you have something that reverts your desktop to an earlier state to when you had a Firefox 56.0 version.

Also your Flash appears to be a old Flash Player 27.0 version when the current Flash Player version is 31.0.0.122

It is possible that you have both 32-bit and 64-bit Firefox versions installed.

The user agent in the System Details list shows a 32-bit Firefox 56 version.

• Mozilla/5.0 (Windows NT 6.1; WOW64; rv:56.0) Gecko/20100101 Firefox/56.0

It is possible that you also have a recent 64-bit Firefox 62 version installed, so check that.

• (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
• (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

You can find the full version of the current Firefox release (62.0.3) in all languages and all operating systems here:

• https://www.mozilla.org/en-US/firefox/62.0.3/releasenotes/

Thanks for the help guys! Instead of just updating I completely uninstalled the previous version of firefox which was version 56 and reinstalled the latest version. It seems to be staying now. Thanks!
