Bug https://bugzilla.mozilla.org/show_bug.cgi?id=521216 is still present in my system but the Bugzilla link (above) states that it was resolved.  So, I'm starting another one.  The example errors shown in this link .......[URL=http://img442.imageshack.us/i/fferror.gif/][IMG=http://a.imageshack.us/img442/8053/fferror.th.gif][/IMG][/URL]
were produced today but I first noticed them yesterday.  That Error Console image above actually had over 500 of those errors in it.

This is not a consistent error.  I can use Firefox for an hour then all of a sudden I'll notice the errors in the error console.  I've been attempting to monitor the situation but it seems to be erratic and when it starts it produces a huge number of those errors.

I spend a lot of time on the MozillaZine board and it's during that work that I've notice this happening ... but that is not to say that other browsing to other sites don't do it.



Reproducible: Sometimes




When I start seeing these errors going into the log then it's constant and if I stop Firefox and then restart it, some time goes by until it starts again.  And, in fact it has not happened while I'm typing all this out and switching around in an attempt to activate the issue.

The following is a sequence that I noticed yesterday.

- I was in the Support section of MozillaZine.
- Right-click a Topic and open in a new Tab
- Click on that Tab and start reviewing the post.
Moved arrow down to Win7 task bar (hovered over the bar-tabs down there), hovered over the Error Console window (it expanded) and noticed about 5-7 of those errors going into the Error Console window... proceeded to move the arrow back over to the Firefox tab/window and while that was starting to expand I saw another bunch of those errors go into the Error Console window... moved the arrow back and forth and each time I did that more of the errors would appear.
- Proceeded to post a reply to an OP's problem and then Previewed my post (which goes into a different and more option rich window (Smilies etc.) and then I move down to the Win7 task bar again, hovered over the Error Console window and notice now that hundreds of same errors were creating many,many pages of the same error and then finally stopped.  Why the mass number of errors for that Preview page... I don't know... perhaps due to the smilies being animated?  

Further testing performing the same routine continued to create those errors. 
I closed all FF tabs, cleared out the Error console and then closed/restarted FF and the above scenario did not start again until about 1/2 hours later.

The same errors hit the error file today.

This is my first Bug posting so I'm sure that I did something wrong so please feel free to fix my post or correct me on something posted wrong.
bug 521216 was about the 3.6 branch. this is about 4.0 + it is a dupe of bug 563337
