Comment 5 for bug 378265

They are not the same bug.
Uninstalling the extensions may not be enough since a lot of times removing them doesnt remove the .xpi. Please remova all and start a new profile. This is not a thunderbird issue but it is an extension issue.
I'm closng this bug at this time.

Please dont move bugs to in progress unless you are fixing it.
Also dont move bugs back to new or they are likely to get lost.
