Getting "error on get FFWin32" at every start of FF4

more options

I upgraded to the new Firefox version 4. At every start of Firefox, there are three error messages that appear one after another in a small error dialog box.

1. "error on get FFWin32"

2. "the C++ xpcom not loaded."

3. "get this._commanager failed"

After I confirm the last one, FF4 opens without any further problems. Please fix.

Thank you Cww. In my case, the problem was solved by disabling the Add-on "FFLinkedNotes 1.0.0.0" (enables creating linked notes for firefox in OneNote).

I don't have the FFlinkednotes add-on, and I still have the the 3 messages on start up.

I am also getting the same 3 error messages when I am on a WEB site that wants to open a side window, for comments. I believe it's a 64 vs 32 bit problem. The comments window that I mentioned uses 32 bit. I hit OK on each of the 3 error messages and the window opens. The 32 bit support is there, but I have to go through the error messages to get to the window.

I was also able to resolve the problem by disabling the FFLinkedNotes extension. To the person who said they don't have this, please check under "extensions", as this is an extension, not a plugin.
