Hello.

You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode and select Disable all add-ons. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.

If you want support for one of your add-ons, you'll need to contact its author.

Do you mean shortcuts that you have created on the desktop or bookmarks?

Make sure that you not run Firefox in Private Browsing - Use Firefox without saving history mode. In Private Browsing mode some menu items are disabled (grayed) and some features like visited links and others are disabled and not working. You are in Private Browsing mode if you see "Tools > Stop Private Browsing". See Private Browsing - Use Firefox without saving history

You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History" To see all History settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history UnCheck: [[ ] "Automatically start Firefox in a private browsing session"

Solved the problem!!! Go into add-ons, click plugins on left, and disable "Silverlight plugin". A half second later, my icons returned
