So I tried to download the latest version of the Mozilla Firefox software and installed but the problem still exists. This time I am not getting any runtime error, but there is nothing happening behind. So the only solution for this kind of problem is a clean installation.

Solution : 

  1. You need to remove the current Firefox browser installation from your computer.
  2. Download the fresh and latest version of Firefox from Firefox website

http://www.mozilla.org 

  1. Once you have downloaded the software, install it in the computer.
  2. You may get some error likeFirefox folder is corrupted,  Mozilla shortcut is missing. So still we have some issues even after reinstalling the new version of Firefox.
  3. So now I reinstalled the software and while installing the software, I changed theinstallation path to D: drive 
  4. To Install the Firefox software in D: Drive then you must choose Setup Type as “Custom”  and press Next.

mozilla setup

  1. When you make the installation path to D Drive, you won’t get any issues now and the Firefox browser open without any problem.
  2. Finally, we solved the issue of  “could not find the Mozilla Runtime” Error.

Finally mozila browser is back

    My home pc received the “could not find the mozilla runtime” when I double-clicked the icon earlier today. A few hours later I noticed that all the icons that were on the desktop had vanished, leaving me with nothing to access the computer. It’s currently running on Windows 7. Is there anyway to resolve this issue?

    Thank you Suresh as I was panicky when I suddenly encountered this problem. I uninstalled and reinstalled with no problem. Thank you for documenting the solution. I was not even prompted for a custom installation. Everything seems to work fine. Again thank you.

  5. If I uninstall Firefox I cannot access the web to reinstall it. How can I resolve this?

  6. Thank you for this post. It works and my old bookmarks are also restored.
