Isn't this considered a bug?  I don't think it happened with previous versions.  Can someone please address it?  Thanks.

This also happens to me.  I just got a new revision to firefox a few days ago, and it hasn't happened since then.  When it happens, I wait, but get the same message again.  I have solved the problem by using another browser, usually chrome, and then when I close chrome, firefox will work normally.

This happens to me on average once a day. 3.5 does not fix this issue.

Just received update this week for Firefox/3.5.4 GTB5 (.NET CLR 3.5.30729).  I'm now having the same error message.  All computers in my office use Windows XP.  Having problem on all computers since last update.  Any fixes yet?

Reporter, please retest with Firefox 3.6.12 or later in a fresh profile (http://support.mozilla.com/kb/Managing+profiles). Also update your plugins (flash, adobe reader, java, quicktime, silverlight, etc.) Go to the developer's website and download the latest version from there. If you no longer see this issue, please close this bug as RESOLVED, WORKSFORME. If you do see the bug, please post a comment.
