A couple of days ago I started geting the error msg -Permission denied for to <webpage> get property XPCComponents.classes. It happens with every webpage I visit. If I hit the x in the upper righthand corner I can then access the page. This doesn't have in IE. Any ideas how I could fix this and why it started happening?

Chosen solution

Try the Firefox SafeMode to see how it works there.
A troubleshooting mode, which disables most Add-ons.
(If you're not using it, switch to the Default Theme.)

  • You can open the Firefox 4.0+ SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
  • Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.

Don't select anything right now, just use "Continue in SafeMode."

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.

If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.

When you figure out what is causing that, please let us know. It might help other user's who have that problem.

If you look in the Error Console for that XPCComponents.classes error, there should be a Source file: chrome:// address which might give us information related to which extension is causing that message.

Firefox button > Web Developer -> Error Console or just use {Ctrl + Shft + J} from the keyboard

I think this is the information you asked for from the error console- chrome://browser/content/tabbrowser.xml

I know the add on was called openinfocard Identity Selector.


Thank you!!!!!!!!!!!
