Problems with functionality

Video, music, or games are not playing

Try checking the Adobe Flash Player plugins, or disabling Turbo mode or browser extensions.

Check the Adobe Flash Player plugin

More often than not, problems with playing videos on sites is due to errors in the Adobe Flash Player plugin used for videos. It is possible that the browser is using several Flash player plugins and one of them is conflicting. Check the plugins used:

  1. In the SmartBox, enter the address browser://plugins.
  2. Press Enter.
  3. In the right part of the Plug-ins window, click Details.
  4. Expand the page and find the section with the header Adobe Flash Player.
  5. If there are several Shockwave Flash plug-ins in this section:
    • Disable the first plug-in and restart the browser.
    • If the error with video persists, enable the first plug-in again and disable the next one.
    • Restart the browser and check for errors.
    • Repeat these steps until you find the plug-in that's causing the error.
Note. For example, in the Adobe Flash Player section, click the first Disable link and restart the browser. If the error persists, turn the first plug-in back on in the same section and disable the next one. Restart the browser and check whether Flash is played. Follow these steps until you find the conflicting plug-in.

For more information, see the section Plug-ins.

The browser doesn't support NPAPI and Unity

The newest versions of the browser no longer support the NPAPI plugin that was previously embedded in the browser and used for Unity Web Player, since this technology is outdated now. Note that Unity has announced that they are ending support for their plugin.

Install the new secure version of Adobe Flash Player with PPAPI support.
