I installed Flash 3 times after checking plug ins on FF 30 Updated 10th May. plug Ins still say it's outdated. I have restarted both the browser and PC. Now FF is crashing and video's not playing properly.

First, remove the "Movable Firefox Button 1.4" add-on. It doesn't do anything as of Firefox 29 (not even alongside Classic Theme Restorer).

You have two versions of Shockwave Player ("Shockwave for Director") installed. You should perform a clean install. Note that you shouldn't install Shockwave Player unless you know for a fact that you need it.

  1. From the following page, save the uninstaller, the full installer for Netscape, and the full installer for Internet Explorer if you also need it in that browser.
  2. Exit all applications.
  3. Run the uninstaller.
  4. Restart your computer.
  5. Run the installer for Netscape.
  6. Run the installer for Internet Explorer if you downloaded it.

Perform a clean installation of Flash Player as follows.

  1. From the following page, save the uninstaller somewhere handy, like the desktop.
  2. From the following page, save the installer for other browsers. If you also use Flash Player in Internet Explorer, also save the ActiveX version.
  3. Exit all applications.
  4. Run the uninstaller.
  5. In Windows Explorer, try to open the following folders. If they still exist, delete them manually.
    • C:\Windows\system32\Macromed\Flash\
    • C:\Windows\SysWOW64\Macromed\Flash\
    • %AppData%\Adobe\Flash Player\
    • %AppData%\Macromedia\Flash Player\
  6. Restart your computer.
  7. Run the installer for other browsers.
  8. Run the ActiveX installer if you downloaded it.

There are other things that need your attention.

Your System Details list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts.

The user.js file is only present if you or other software has created this file and normally it wouldn't be there. You can check its content with a plain text editor (right-click: Open with) if you didn't create this file yourself.

The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

You can use this button to go to the currently used Firefox profile folder:
