See also bug 543494.

Bug 605741 is fixed in Aurora (Firefox 10), maybe it helps.
You can download and test Aurora here:

Yes, you are right.
In safe mode, nothing has changed. Here is video of the problem: chmelik.com.ua/702239.avi
When saving data (on video) one of the cores loaded on 100%.

If a problem disappears when running in safe mode it's likely a problem with an add-on. You may try to track it down by disabling all add-ons and the enable them one by one until you find the culprit.

This video was recorded with disabling all add-ons. I think it not them.
IMHO this bug associated with component "textarea".. early (before ff4) this component had "fixed" size, but from ff4 it sizeble (such as Chrome)
